About Me
I have been a Sion main since his rework. I have obtained over 800,000 Mastery Points on Sion across my accounts. In Season 6 I reached Diamond with a 68% winrate on Sion over 169 games. He has been my favorite champion in League since his rework.
Champion Spotlight Back to Top
Sion Intro Back to Top
Sion is THE most versatile tank is League of Legends. He is able to adapt to each game unlike no other tank. Many people even play Sion as an AD assassin or bruiser including Thebausffs and Tilterella both Challenger AD Sion mains and streamers. He is always going to be a great tank who can fill the role that is needed for his team. Sion is very easy to learn but also has the highest skill-cap of any tank in the game, making him a both a great champion for new players and for masters alike. I suggest you use this guide as a foundation to find your own way to play that works for you. Don't strictly follow everything in the guide, decide what works best for you and how you play best. There's no one "right" way to play or build this champion and you'll find that most high elo Sion players have drastically different play-styles and builds.
Sion Abilities Back to Top
P Glory in Death
Innate: After being killed, Sion will reanimate with rapidly decaying Health. His attacks become very rapid, gaining 100% Lifesteal and deals bonus damage equal to [+10% target's max]
All his abilities are replaced with Death Surge.png Death Surge, which grants a burst of Movement Speed.
Q Decimating Smash
Active: Sion charges up a heavy blow for up to 2 seconds. When released, he deals physical damage to enemies hit (60% damage to minions) based on how long Sion charges and briefly slows them.
If Sion charges for at least 1 second, enemies are knocked up and stunned for 1.25 to 2.25 seconds.
W Soul Furnace
Passive: Sion gains 4 maximum Health whenever he kills a unit (15 for champion kills, assists, large minions and large monsters).
Active: Sion shields himself for 6 seconds. After 3 seconds, while the shield holds, Sion can reactivate to deal magic damage to nearby enemies. Max 400 bonus damage against minions and monsters.
E Roar of the Slayer
Active: Sion fires a shockwave, dealing magic damage to the first enemy hit and knocking it back if it is not a champion (significantly increasing its range).
Target's hit by the shockwave or the knocked back unit take the same damage and are slowed for 2.5 seconds and have their Armor reduced by 20% for 4 seconds.
R Unstoppable Onslaught
Active: Sion charges in a direction for 8 seconds and can steer slowly towards the mouse cursor. While charging, Sion is immune to all Crowd Control. Reactivating will cancel Sion's charge early.
When Sion collides with an enemy champion or wall, he deals physical damage and knocks up enemies in a small area for 0.75 seconds. Enemies in a larger area take the same damage and are slowed for 3 seconds.

The damage increases and the stun duration increases to 1.75 seconds as Sion charges further.
Sion Eternals Back to Top
Eternals were added to the game in patch 10.5. They are a (paid) way to track achievements for a specific champion. Sion currently has 3 unique Eternals.
Smash'em Up
Tracks total enemies knocked up by Decimating Smash

Well Fed
Tracks bonus health gained from Sion's Soul Furnace passive

The Pain Train
Tracks the total number of enemies that you hit with Sion's maximum speed (950 movement speed) ult Unstoppable Onslaught
Sion Matchups Back to Top
View the Sion Matchups section under the "Tank Sion Top or Mid" build. Currently most matchups are focused on top and mid lane. Click "Show All" under the picture of Sion in the Threats & Synergies area to expand and see everything.

General Rule for Counters and Synergies

In general, Sion is countered by high mobility, %hp damage, hard CC/skillshots, and bruisers.

Every one of Sion's abilities are very telegraphed, making them very easy to dodge by champions with high mobility.

Sion is a health stacking tank, making %hp very effective against him.
Hard CC and skillshots are very effective against Sion because he has to charge up his Q, making him a vulnerable target.

Bruisers as a class in general are designed to do well against tanks, they do higher damage than tanks, usually have some form of %hp damage or armor shred, as well as having higher mobility at the cost of having less CC and defensive abilities than a tank.

Since Sion has very telegraphed but hard hitting abilities, he pairs very well with other champions that have easier to land/setup CC. Sion's ult and Q are much easier to land on targets that are already CC'd. Champions like Nautilus with a ton of CC make life as Sion much, much easier. Also, Sion is a great setup for other champions, such as Yasuo that need enemies to be CC'd for them, although Sion is not the best at this because his abilities are so telegraphed.
Sion Runes Back to Top

Resolve Tree

Grasp of the Undying is great on Sion. It does damage based on your max health, heals you, and gives you permanent health every time you proc it.
Demolish is another great rune for Sion. It also scales with your health allowing you to kill towers very fast as a tank! Shield Bash can be good on Sion as well for better trades in the top lane. If you want better trades in lane and massive shield damage late game take Shield Bash. If you think you can win your lane hard and hit the enemy tower for free often take Demolish.
Conditioning, Second Wind, and Bone Plating are all equally good on Sion and are completely situational. Conditioning is the best option outside of laning phase, if you are against an easy lane take it. Second Wind is good against poke lanes. Bone Plating is the based overall rune in this tier for trading, making it the best overall option in most situations. If you are unsure what to take in this tier just take Bone Plating.
Overgrowth is the best rune option in the bottom tier of the Resolve tree. It gives you permanent health when minions die near you. Sion is a health tank so this is always a great option on him. If you need help in the laning phase you can take Revitalize which will increase your shield strength. If the enemy has a ton of CC, think about taking Unflinching instead as it will help you deal with the CC.

Sorcery Tree

Arcane Comet Is a fantastic rune on Sion for the laning phase. Sion's Q Decimating Smash and his E Roar of the Slayer basically guarantee the comet to hit. This gives a Tank Champion like Sion insane poke in the laning phase, allowing him to deal with ranged matchups and easily beat them. If you go Arcane Comet start Doran's Ring and max his E Roar of the Slayer.
If you took Comet I'd recommend taking Manaflow Band as well, giving Sion the mana to be able to spam his e nonstop in the laning phase.
Transcendence should be taken next, giving Sion an easy 10% extra CDR.
Scorch is very good in this rune page. It increases Sion's poke damage by a lot.

Inspiration Tree

Glacial Augment is a good rune to take if your team needs more engage. It also makes Sion's Q Decimating Smash a lot easier to land. If you go Glacial Augment buy Righteous Glory second or third item allowing you to run very fast into the enemy team and slow them with the freezing rays from Glacial Augment.
Magical Footwear and Perfect Timing are both solid options to take next. Magical Footwear is good if you don't need to buy Ninja Tabi early. Perfect Timing is good if you think the enemies will dive you top lane. Keep in mind, both of these runes take a while to activate.
NERFED 9.16 Biscuit Delivery may not be viable to take every single game now. It should still work in difficult matchups but may not be ideal otherwise. If Inspiration is your secondary tree I would try taking Magical Footwear instead. If Inspiration is your primary tree I would still take Biscuit Delivery in most situations.
Cosmic Insight, Approach Velocity, and Time Warp Tonic are all good runes at the bottom of the Inspiration Tree. I prefer Approach Velocity, it gives you movement speed when you run towards enemies that you CC. This is great on Sion because if you land Roar of the Slayer you will be able to catch up to them and use Decimating Smash. This also makes for an amazing synergy with Glacial Augment and Sion's Passive Glory in Death allowing you to chase people way easier.
Sion Items Back to Top

Starting Items

For Sion's first purchase you can decide to go Corrupting Potion, Doran's Shield + Health Potion, or Doran's Ring + Health Potion x2.

Corrupting Potion is great in every scenario and works with any build. It provides amazing sustain and damage for the laning phase. If you are new to Sion I would always recommend starting Corrupting Potion. Use Corrupting Potion offensively to win trades.

Doran's Shield is a great start against poke and ranged champions. It will reduce their poke by a ton but also gives you no mana sustain so watch your mana when taking Doran's Shield.

Doran's Ring is a good start if you want to poke the enemy. This will increase your E Roar of the Slayer damage by a large amount and allow you to spam it much more. Buying Doran's Ring will force your Adaptive Force to give you AP instead of AD. Starting Doran's Ring will give Sion's E Roar of the Slayer +18 damage at level one and Sion's W Soul Furnace +13 damage at level one while also increasing Arcane Comet damage if you took it. This will increase your ability to poke by a large margin, making Doran's Ring a great start against ranged matchups that you want to poke down. Look to spam E Roar of the Slayer and if it lands charge your shield and channel Q.


Sion can go either Ninja Tabi or Mercury's Treads depending on each game. Look at the enemy team and your laner. If you are against a heavy AD team go Ninja Tabi, if you are against a heavy AP or heavy CC team go Mercury's Treads. In most cases you will probably end up buying boots early to counter your laner. If you're against a heavy auto-attacker like Tryndamere, you'll want to get Ninja Tabi very early to reduce the damage of his basic attacks.


Frozen Heart is REALLY good on Sion. Sion gains health from his W passive Soul Furnace so buying straight armor is extremely effective on him. This item also gives Mana, 20% CDR, and a unique passive that slows attack speed. This is THE best armor item for Sion against AD auto-attackers. Get this item first or second in most of your games if you are against AD auto-attackers.
Sunfire Cape is great on Sion as well. It has been changed in patch 10.4. It will now do bonus damage when you immobilize enemies (damaged based off max health). These changes should make Sunfire Cape very good on Sion and will allow him to do much more damage.
Righteous Glory works really well on Sion IF you take Glacial Augment. This is a great combo that allows Sion to engage very easily, even without his ult. IF you have Glacial Augment, buy Righteous Glory second or third depending on the enemy team.
Thornmail is a niche item that should be purchased against champions with high lifesteal. Thornmail will reduce their healing when they attack you making it very effecting against lifesteal champions and items. Only buy this item if you see the enemy has high lifesteal that might be hard to deal with. If you are laning against a champion with a lot of lifesteal, buy Bramble Vest early but don't upgrade to Thornmail until later in the game. Buy or finish Thornmail third, fourth, or as your last item.
Randuin's Omen is another niche item. It will reduce the damage you take from critical hits as well as having an active that will slow all enemies around you. Only buy this item if you are against multiple AD opponents with high amounts of critical chance.
Knight's Vow is typically a support item. This item can be purchased on top or mid Sion if your ADC needs more peel. If your team does not have a tank support and your ADC is fed I would consider buying this item and peeling for them.

Magic Resist

Abyssal Mask is a good first item on Sion against magic damage opponents. If you are going Arcane Comet and maxing Roar of the Slayer then this is a good purchase. It will help you sustain in the early game, as well as increasing the magic damage that enemies take from ALL sources while you are near them.
Spirit Visage is good as a pure magic resist item. Take this if your team has high healing OR if you plan on buying or already own Warmog's Armor. This is a good second or third item.
Adaptive Helm is a good but niche item. It is great against damage over time magic damage champions. Take this item against champions like Teemo, Rumble, Singed, Corki, Cassiopeia, etc.


Warmog's Armor is an amazing item on Sion. Sion is one of the few, if not the only champion that can buy Warmog's Armor second item and activate the passive Warmog's Heart which heals you a TON out of combat. Sion can buy this item so early because of his W passive Soul Furnace, allowing him to have 3000 health by his second item if he buys Warmog's Armor. This item is actually ridiculous on Sion, it allows him to take short skirmishes then walk out of combat for a few seconds and come back with full health. This is a very underrated item on Sion and should be taken as Sion's second item if possible. Warmog's Armor is currently the highest winrate item on Sion out of any item with a 60% winrate!

Magic Resist + Armor

Gargoyle Stoneplate gives armor and magic resist. This item makes Sion insanely tanky in teamfights. This can be a really good mid-late game item. I would take this item third item or later.
Zz'Rot Portal ITEM REMOVED FROM THE GAME AS OF PATCH 9.23..... RIP it was a fun item that was pretty good on Sion.
Locket of the Iron Solari is typically an item that supports buy. While it is typically a support item is can be a great purchase on Sion top or mid. If the enemy team has a lot of AOE damage and your teammates are getting bursted consider getting this item. ONLY buy this item if you do not have a tank support on your team who is going to buy it. If you are going to buy this item, get it very late in the game, usually 4th or 5th item.
Who to Watch Back to Top
There are some great Sion mains to watch to get better at Sion. Thebausffs is an EUW Sion one trick who is consistently in high Challenger by playing AD Sion and occasionally tank (bruiser) Sion. He is THE master of this champion. He streams on Twitch very consistently and has a Youtube channel. He just released a very in-depth Sion guide which I highly recommend you watch if you want to get better at Sion. Tilterella is also a great Sion main to watch. He has a Youtube channel with over 350k subscribers and most of his content is related to Sion. He also has a Twitch stream. He plays on the OCE server and has managed to get very high elo including Challenger in the past.
Tank Sion Top and Mid Back to Top

Tank Sion

Building tank on Sion is the most common and well-known way to play Sion. It is highly recommended for new players to try tank Sion first to learn the kit. Tank Sion is easy to learn but hard to master. I main tank Sion top, it is my favorite way to play him. Building tank on Sion insures that even if you have a hard time in lane you can still by useful by engaging or peeling for your carries.

Top Tank

I would recommend going top lane if you are going to go the traditional tank build on Sion. Going top lane on Sion allows you to have the best laning phase possible and fit your team comp.

Mid Tank

Sion mid is actually not bad. Many people have played it in the past, even Faker has played Sion mid! I would only recommend doing this if your top laner is a carry and your team absolutely needs a tank. Also insure your team has enough magic damage before locking in Sion mid. Going mid as Sion allows you to roam a lot more than you would as a top laner. Sion mid can absolutely destroy many mid matchups. Picking Sion into a Zed mid, for example is an easy way to make a Zed ragequit. Sion, unlike other tanks does really well against ranged matchups so you can do really well against many mid laners. Make sure you take Arcane Comet and buy Doran's Ring. Max E Roar of the Slayer and poke down the enemy laner. You will deal a lot of poke damage while being able to block the enemy poke with your W Soul Furnace. Look to build a large wave and crash it into the enemy tower then roam top or bot. Your ult is really good for roams.
AD Sion Top Back to Top

AD Sion

AD Sion is an incredibly fun and viable way to play Sion. Building lethality on Sion essentially turns him into an assassin. Sion's Q Decimating Smash has ridiculous AD scaling, allowing you to almost one shot enemies if you can get a full Q off. If your Q Decimating Smash doesn't kill them, they will be cc'd for a long time allowing you to use your other abilities to finish them off. While playing AD Sion you are going to want to camp in bushes a lot. Enemies CANNOT see when you are channeling your Q Decimating Smash from a bush UNLESS the bush is warded. This allows you to pull of some sneaky oneshots from bushes. Even when you die as AD Sion you will run down the enemies with your passive, possibly taking one or more enemies with you. I don't main AD Sion but I love to play it sometimes on my smurf, it is incredibly fun to play. Several Sion mains have managed to reach Challenger one tricking AD Sion.

Here is a great video by ****HuaP explaining why AD Sion works
Note: Some of the information is outdated
Support Sion Back to Top

Support Sion

Support Sion is probably Sion's second best role. While not many people play Support Sion, it can be quite good. Sion as a support is very aggressive, all of his abilities can potentially hit both enemy bot laners. Make use of the bot lane bushes to charge your Q Decimating Smash on the enemy both lane, they cannot see you charging it if the bush is not warded. He will not be as tanky as he would be top lane so you need to be more careful. Try to pair with an aggressive ADC and stomp the early game. Try to peel for your ADC lategame, don't ult too far away from the carries or they might die alone. If you secure an early lead use your lead to get vision in the enemy jungle and near dragon. You should not lose a single dragon early game if you win hard bot lane. Make sure dragon is always clear of wards and use wards in the enemy jungle to spot where the jungler is going. You can max either E Roar of the Slayer or Q Decimating Smash on Support Sion. Q Decimating Smash max is good if the enemy bot lane has low mobility and can easily get hit by Q. E Roar of the Slayer is good to max first against poke lanes and more mobile lanes. As Support Sion ALWAYS max W Soul Furnace second.

High Elo Support Sion Game

Here is an example of a high elo game as Support Sion. This gameplay is NOT ME. This is a good example of how you should play as Support Sion in the laning phase.
Jungle Sion *Buffed 9.16, 10.20* Back to Top

Jungle Sion

Sion jungle has been buffed in patches 9.16 and 10.20. His Q Decimating Smash no longer does reduced damage to monsters and its base damage has been increased in the 9.16 patch. In the 10.20 patch his Q now does 150% damage to monsters, this is HUGE for jungle Sion and also decent for lane Sion. Sion Q, fully charged could potentially outdamage a smite now! These changes could make Sion jungle viable again, improving his clear speed by a large amount. Sion's weaknesses in the jungle will still remain, he will still not clear as fast as many junglers and his pre-6 ganks are not ideal without Predator. Sion jungle does scale much better than top lane Sion though. Enchantment: Cinderhulk gives Sion a ridiculous amount of health in the late game. If the enemy does not have percent health damage you will feel unkillable.

Clear and Tips
Start Red buff with W start. Channel your W just before the buff spawns, take a couple hits then pop your shield for the damage. Kite the red buff by moving towards Raptors after each auto. Put a point in Q next and full charge a Q on the Raptors and press W at the same time, take some damage before popping your shield but don't let your shield get destroyed or your damage won't go off. Smite the large Raptor near the start of the fight with the Raptors. I like to go Krugs third as it will let you reach level 3 with only 3 camps and when they respawn they will give you more xp than other camps. Use the same method of full charging a Q and W at the same time for the Krugs. Kill the small one first then the big one. After Krugs you can decide to either go for Scuttle Crab or go straight to Blue buff. I usually go to Blue buff because Sion can't contest most junglers at Scuttle early on. If you go to blue, smite it and kill it. Go to Gromp then Wolves for a full clear. Recall unless you find a great opportunity for a gank. Buy boots for Predator and either upgrade your jungle item or get a Bami's Cinder. With Predator you will actually be able to gank now. Activate Predator right before you run into the enemy lane so they don't have much time to react. As Sion you should always be buying Control Wards and eventually get red trinket. Knowing that a bush is not warded is important for Sion to setup kills and/or ganks.
Bruiser Sion Top Back to Top

Bruiser Sion Top

Bruiser Sion is great in patch 10.5. Both Sunfire Cape and Titanic Hydra have been buffed. These item changes allow Sion to stack health and actually deal more damage with the more health he gets. I would argue that Bruiser Sion is better than full tank in patch 10.5. Bruiser Sion has some great item options, you can decide to build tankier or go more of a damage route. The two core items you should ALWAYS get on bruiser Sion are Sunfire Cape into Titanic Hydra. The rest of the items are up to you based on the situation. I listed a bunch of solid options in the builds section at the top of this guide. Ingenious Hunter in the Domination rune tree reduces the cooldown of Sunfire Cape AND Titanic Hydra as of 4/5/20 (Patch 10.7).
Smite Lane Sion Back to Top

Smite Lane Sion

Smite Sion can work in lane to stack a ridiculous amount of health. Enchantment: Cinderhulk increases your health by 15% which is crazy on Sion because his Soul Furnace passive gives him so much health already. Smite lane Sion is VERY vulnerable to ganks in because you have no flash with this build. You need to play safe, freeze the wave and try to farm up. You will scale very well into the late game with the 15% health increase from Enchantment: Cinderhulk. Avoid using this smite build against strong early game top laners and junglers. Also if the enemy team has % health damage like a Vayne you should not go with this build.
AP Sion Back to Top

AP Sion

AP Sion is admittedly kind of a troll build. It can be very fun to play in normals but I would not bring it into ranked unless you are able to consistently do well with it. Sion's AP scaling is not horrible but it's not quite up to par with other AP champions and he only has 2 abilities with ap scaling (his e and his w). If you want to change it up every once in a while with Sion I'd definitely try it as it's a very fun build. This build has some solid burst while still having the great utility and CC that Sion provides.
Tips and Tricks Back to Top
  • Sion's ult Unstoppable Onslaught can damage towers. You can use this to get a surprising amount of damage off (more if you are building AD). Keep in mind, you should not be ulting a tower unless you have minions near the enemy tower as allied minions lower the resistances of the tower by a significant amount. Your ult does more damage the further away you use it as well so consider walking back a bit before ulting a tower. The best use of this is when you are pushing for the end of the game. If you have minions on the enemy Nexus towers ult from just behind an enemy Inhibitor, aim for the middle in between the two towers. Instead of directly ramming into one tower cancel your ult in the center between the two towers. This will do damage to BOTH Nexus towers. This can easily do 700-800+ damage to both Nexus towers at the same time and much more if you are building AD.
  • Sion's passive Glory in Death can be used to "cheese" the enemy jungle camps level one. If you are on blue side you can go to the enemy raptors at level 1, make sure the area is clear. If the area is clear attack the raptors and get very low health, when you are about to die start running towards the red buff. When you die use your passive to steal the red buff, you WILL keep the red buff when you respawn, TP back to lane after you steal the buff. If you are on red side you can do the same thing but with the enemy blue buff. There are two ways of doing it on red side. You can get low on wolves then run over to blue buff and kill it with your passive. The other way to steal on red side is to attack the blue buff then attack the gromp, stand in between both to keep aggro. When you die kill blue buff with your passive then kill gromp with your passive. TP back to lane after with your blue buff!
  • Despite what many people think Sion is NOT a strong late game champion. Sion is strongest in the mid game. Use your mid game powerspike to make plays, you will be a lot stronger than most enemies at this point. The longer the game goes the harder it will get, their ADC and any Liandry's mage will shred you late game.
  • Another misconception is that Sion is an engage champion. While this is partially true, Sion is not a reliable engage and serves best as a followup to another ally's engage. Sion's abilities are much more useful when an ally is able to CC the enemies first. Sion, for this reason pairs really well with engage tanks such as Sejuani.
    If a Sejuani ults for example, you can follow with your ult into Q and CC multiple enemies for several seconds, this should be enough to win a teamfight. With the help of another tank you can CC lock enemies for their entire lifetime.
  • Take a moment every game to see what your team needs. Do you need to engage or peel? If you have a fed ADC and he is dying easily stick to him like glue. If your ADC gets really fed and you do not have a tank support on your team look to buy Knight's Vow and/or Locket of the Iron Solari.
  • Sion can "jump" over player-made terrain such as Azir R Emperor's Divide, Anivia W Crystallize, Trundle's E Pillar of Ice, Yorick's W Dark Procession, and Jarvan's R Cataclysm. To pull this off you have to use your ult as Sion Unstoppable Onslaught and run at the terrain. Right before you hit the terrain cancel your ult and you will jump over it. The interaction with Azir's wall is the buggiest and may only work sometimes. The best way to jump over Azir R is to hop over AS he casts his ult. Here's a great video by Vandiril showcasing this trick:
  • Sion's R Unstoppable Onslaught makes him immune to CC while active but does not break any existing CC. This means abilities such as Nasus' Wither will make your ult start a lot slower.
  • Use Sion R to block the CC of an incoming gank instead of flashing. An example would be if you are getting ganked by an Elise and if she lands her Cocoon you know you will die. Instead of flashing her Cocoon, ult for the CC immunity and run to safety. Don't do this if your ult could be block by terrain or enemy champions. It's more important to use your ult than flash here because your ult is a way shorter cooldown and is generally less valuable than flash.
  • Enemies CANNOT see Sion's Q Decimating Smash cast if Sion is hidden in a bush while charging. You can use this to great effect toplane by full charging Q's from the bushes while the enemy is trying to CS. If you do this enough, the enemy will be scared to walk near any bush without vision.
  • Sion can buffer his E Roar of the Slayer into flash. Press E then flash instead of flash then E. This is much faster than flashing then E'ing and can make the difference in getting a kill or not.
  • A simple way to surprise kill an enemy is to charge up your W Soul Furnace shield then E Roar of the Slayer + Flash and at the same time pop your W Soul Furnace and flick Q Decimating Smash for a surprising amount of burst damage. I have done this countless times to catch my opponent off guard. No one expects you to burst them like that. The best way to do this is when the enemy is low under tower and is overstaying for CS and XP. They will have very little time to react with this combo.
  • Sion's E Roar of the Slayer no longer does increased damage when throwing a minion at an enemy. It now will apply the armor reduction though as an AOE, all enemies hit by the minion you throw will have their armor reduced. Try to throw a minion and hit multiple enemies during or before a teamfight to reduce their armor. If you manage to hit a few and your allies are nearby look to ult.
  • Sion's ult Unstoppable Onslaught is very easy to land if you land your E Roar of the Slayer first. Like stated before, if you can throw a minion from far away and hit someone you can look to ult. This is one of the best times for you to use your ult.
  • Sion can ult through many areas that people may not know. An example of this is ulting from your base to Baron or Dragon. I would recommend going into the Practice Tool and practicing these ult paths. Many of these are very difficult to pull off and I would not recommend attempting them in a ranked game unless you are very comfortable. Here is another great video by Vandiril showing many of the paths you can take:
  • Sion's R Unstoppable Onslaught can essentially bounce off of many walls. You can use this to get some very unique angles on your ult. This is usually pretty inconsistent and you have to hit the right spots in the walls. Sometimes your ult will just end by hitting a spot in the wall while other times you will bounce off it and make a cool play. The best way to be consistent with this is to start parallel to a wall and slowly approach the wall at a 10-15 degree angle. If done correctly you will bounce off the wall! Keep in mind this does not work on every wall, in general it works with walls that bend slightly. A great example of this is right next to the bot lane tower where the wall starts to bend.
  • You can use the F-keys (f1,f2,f3,f4,f5) to move your camera WHILE in Sion's R Unstoppable Onslaught. You can use this to get a more reliable view of what is going on. This is great for when you are ulting down mid lane or bot lane for example so you can see where your ally is in relation to the enemy. The F-keys are organized by your scoreboard. F1 is always you, F2 is the next person on the scoreboard and so on. If I was ulting down mid and I was the top laner I could quickly press f3 to look at my mid laner if he is fighting. This is kinda tricky to get the hang of but it is pretty easy if ulting in a near straight line like down a lane.
  • Wait for enemies to use their movement abilities before you ult, it will make it much easier to land.

W - Soul Furnace PASSIVE BUGFIX When active, Sion's W - Soul Furnace now properly grants him bonus health from kills.

Patch 10.5
If Sion channels R - Unstoppable Onslaught for 3+ seconds and then runs into an enemy champion, he now properly stuns the target for the intended 1.75 seconds

Patch 9.23
When Sion casts R - Unstoppable Onslaught out of its range, the ability will now properly cast immediately instead of after he walks into cast range

Patch 9.19
W base shield increased.
W - Soul Furnace
BASE SHIELD 30/55/80/105/130 ⇒ 50/75/100/125/150

Patch 9.16
Base Stats
MANA 325.6 ⇒ 330

Q - Decimating Smash
BASE MINIMUM DAMAGE 20/40/60/80/100 ⇒ 30/50/70/90/110
BASE MAXIMUM DAMAGE 60/120/180/240/300 ⇒ 70/135/200/265/330
REMOVED REDUCED DAMAGE ON MONSTERS Decimating Smash no longer deals 80% damage against monsters

Patch 9.3
Q damage decreased. W cooldown increased early.
Weakening Sion's early lane to make bad matchups more punshing for him.

Q - Decimating Smash
MINIMUM DAMAGE : [30/50/70/90/110]
⇒ 20/40/60/80/100
FULL-CHARGE DAMAGE : [90/150/210/270/330]
⇒ 60/120/180/240/300
W - Soul Furnace
COOLDOWN : [11] ⇒ 15/14/13/12/11 seconds

Base health regen decreased.
Less health regen means Sion will have to rely more on his shield and health bonuses from last-hitting to stay healthy in lane.

Base Stats
BASE HEALTH REGEN : [9] ⇒ 7.5 per 5 seconds

W health gain increased.
W - Soul Furnace

Q base damage and damage ratio increased at later ranks.
Sion's last round of nerfs was necessary while Banner of Command was the top pick for top laners. Now that the item has been removed from the game, he's landing on the weak side.

Q - Decimating Smash
BASE DAMAGE : [30/47.5/65/82.5/100]
⇒ 30/50/70/90/110
DAMAGE RATIO : [0.45/0.50/0.55/0.6/0.65]
⇒ 0.45/0.525/0.6/0.675/0.75 total attack damage

Base health regen decreased. E base damage decreased, damage ratio increased, and no longer deals bonus damage to secondary targets. E Armor shred now applies to secondary targets; duration increased.
The bonus damage Sion does to secondary targets struck by Roar of the Slayer is just too much: too much waveclear, too much poke, too much long-ranged lane control. By having E apply the armor shred to all targets struck, Q damage will be higher on targets struck by E, and further incentivize him to max Q (or at least to ensure there are more tradeoffs when he does opt into the ranged control E offers).

Base stats
BASE HEALTH REGEN : [10] ⇒ 9 per 5 seconds
E - Roar of the Slayer
BASE DAMAGE : [70/105/140/175/210]
⇒ 65/100/135/170/205
ABILITY POWER RATIO : [0.40] ⇒ 0.55 ability power
SECONDARY TARGET DAMAGE : [130%] ⇒ 100% to targets struck by a knocked-back enemy
ARMOR REDUCTION : [20% to primary target] ⇒ 20% to all targets hit by Roar of the Slayer or a knocked-back enemy
ARMOR REDUCTION DURATION : [2.5] ⇒ 4 seconds
R - Unstoppable Onslaught
COMING THROUGH Sion's ultimate is no longer obstructed by an allied Azir's Emperor's Divide

Q damage ratio decreased at earlier ranks.
Sion doesn't currently sacrifice much damage in order to max Roar of the Slayer instead of Decimating Smash. In return he gains strong ranged poke, which is making him a dominant pick not only in top lane, but also mid in some matchups. There are times when it should make sense to max E first (ranged harass, using the slow to make Q easier to hit), but we want to make this less of a clear-cut choice.

Q - Decimating Smash
DAMAGE RATIO : [0.65] ⇒ 0.45/0.5/0.55/0.6/0.65 total attack damage
FULL CHARGE DAMAGE : [1.95] ⇒ 1.35/1.5/1.65/1.8/1.95 total attack damage

Roar of the Slayer

BOWLING WITH SION : Fixed a bug that made Roar of the Slayer's pass-through damage radius much wider than intended
BOWLING WITH SION IN THE JUNGLE : Jungle monsters launched by Roar of the Slayer now properly damage enemy champions

BASE ARMOR : [23.04] ⇒ 32
BASE ATTACK DAMAGE : [59.72] ⇒ 68

W grants more health for killing small units. R’s max damage increased.
Sion never truly recovered from midseason’s durability item changes. Through this lens, giving him the means to win back some late-game tankiness is fairly straightforward. Past that, we’re packing more punch into Unstoppable Onslaught to bring Sion’s teamfight initiation up to a more appropriately threatening level.

W - Soul Furnace
R - Unstoppable Onslaught
MINIMUM DAMAGE : 150/300/450 (unchanged)
MAXIMUM DAMAGE : [300/600/900]
⇒ 400/800/1200
BUGFIX : Sion is now properly immune to Lulu's Polymorph during Unstoppable Onslaught

W cooldown decreased, shield’s max health scaling increased.
Sunfire Cape followup buffs!

W - Soul Furnace
COOLDOWN : [13] ⇒ 11 seconds
SHIELD SCALING : [6/7/8/9/10%] ⇒ 8/9/10/11/12% Sion’s maximum health

ATTACK RANGE : [150] ⇒ 175

E - Roar of the Slayer
I'M NOT YELLING : Fixed a bug where yelling at an airborne minion would deal no damage
In a world without mana potions (and generally less early mana regeneration), we've identified a few champions for some emergency rations, giving early mana boosts until they can get their footing and purchase items to make up the deficit. This also means we can really understand which champions relied on mana potions as a crutch to limp through the early to mid game, and we can give additional love if necessary.


The following champs have +50 base mana and -3 mana scaling (net -1 mana at level 18):

"Weird bugs, man."
R - Unstoppable Onslaught
USE YOUR OWN AXE, SION : Fixed a bug where Unstoppable Onslaught was scaling with the target's bonus attack damage instead of Sion's

W's health ratio is lower at early levels and takes longer to reactivate.

"The undead hulk that is Sion dies more often to jungle monsters than champions these days, mostly due to the strength of Soul Furnace. While we like that he takes a lickin' and keeps on tickin' (do zombies tick?), Soul Furnace's offensive capability often seals a winning lane for him once he's able to build enough Health, creating a situation for opponents where beefing up makes the shield's damage more effective (as it scales off an enemy's maximum health), while building more damage to pop Soul Furnace opens them up to being crushed by a Decimating Smash. Limiting his shield's flexibility offensively while keeping it sturdy enough to mosh 5v5 should keep him as threatening as ever without being a catch-all solid pick. "

W - Soul Furnace
SHIELD DETONATION TIMER : 2 seconds ⇒ 3 seconds
RATIO : 10% maximum health ⇒ 6/7/8/9/10% maximum health

Q hurts monsters less. E's passthrough damage down.

"Primarily thought of as top tier laner, Cinderhulk saw Sion shamble on into the jungle and dominate without breaking a sweat. The changes themselves are simple enough, but underscore an important point - Sion should be a powerful pick for the crowd control and durability he brings to a composition, not necessarily his damage output (especially when building tank)."
Decimating Smash.png Q - Decimating Smash
Roar of the Slayer.png E - Roar of the Slayer

Q's mana costs down, ratio slightly up. E's mana costs up at later ranks.

"When it comes to Super-Tanks in top lane, we actually like what Sion brings to teams and how he interacts with opponents, with the exception of his laning phase - so we're keeping things "power-netural" for the big zombie. Shifting power from screaming at minions to dropping the chopper on frightened opponents means it requires a little more effort to win the wet-noodle-war than just never running out of mana. "
Q - Decimating Smash
COST : 45/50/55/60/65 mana ⇒ 45 mana at all ranks
RATIO : 0.6-1.8 total attack damage ⇒ 0.65-1.95 total attack damage
E - Roar of the Slayer
COST : 35 mana at all ranks ⇒ 35/40/45/50/55 mana


"Zombies already have Grievous Wounds, man."
Passive - Glory in Death
FOR THEMATIC REASONS? : Fixed a bug where if Sion was killed while affected by a healing debuff (ex. Grievous Wounds), he would revive in his zombie form with reduced health
"We're making readability improvements to a bunch of the champion portrait icons which were added or updated over the past few months."
PORTRAITS : The following champion portrait icons have been updated:
Azir, Cho'Gath, Ezreal, Gragas, Graves, Janna, Jarvan IV, Kayle, Kog'Maw, Lee Sin, Malphite, Maokai, Orianna, Renekton, Rengar, Rumble, Shyvana, Sion, Talon, Tristana, Udyr, Vayne, Veigar, Viktor, Zilean


Glory in Death's health drain has been lowered for higher levels and Sion's health regeneration growth stat has been lowered a bit.

"Sion's been climbing the ranks towards Mundo-hood when it comes to overall longevity and, couple that with the 2015 changes to regeneration, we have a real monster on our hands. In light of that, we're mainly re-mathing out Sion's passive to favor the juggernaut's beefier builds. "
HEALTH REGENERATION GROWTH STAT : +1 health per 5 seconds ⇒ +0.8 health per 5 seconds
Passive - Glory in Death
HEALTH DECAY : 2 x level ⇒ 1 + (1 x level)
HEALTH DECAY GROWTH : 1.4 x level ⇒ 0.7 + (0.7 x level)

Lots of bug fixes along with a small mana cost shift from Sion's Q + W to E.

"We've got a little room to give Sion some post-update love, so we decided to focus on his best stat: health. Additionally, we've made a lot of quality-of-life changes & bug fixes to help Sion be the best he can be. Final note for that passive change, we changed it because it was punishing Sion for building HP, which was dumb. Now health-stacking Sion should stay up a little longer in his zombie form in comparison to a damage-focused, low-health Sion. Logic! "
HEALTH PER LEVEL : +70 ⇒ +73
Passive - Glory in Death
COMPLICATED ZOMBIE MATH : Sion's health decay in passive form now scales with his max health (0.5% max health first tick, increasing by 0.4% max health per tick) ⇒ champion level (2 x level first tick, increasing by 1.4 x level per tick)
FIERY DEATH : Fixed a bug where Sunfire Cape wasn't working while Sion was in his passive zombie state
YORICK IS HELPING : Glory in Death no longer fails to activate in cases where Sion is targeted by Yorick's Omen of Death, doesn't trigger the revive effect and then dies later on in the match
Q - Decimating Smash
COST : 50/55/60/65/70 mana ⇒ 45/50/55/60/65 mana
SMASHING PARITY : All crowd-control types now correctly refund Decimating Smash's cooldown to 2 seconds when they interrupt Sion while he's charging up
YELLING AND SMASHING : Sion can now properly cast Decimating Smash immediately after Roar of the Slayer
W - Soul Furnace
COST : 70/75/80/85/90 mana ⇒ 65/70/75/80/85 mana
PASSIVE HEALTH GAIN : 8 ⇒ 10 on large monster kill and champ kill/assist (minion and small monster bonus unchanged)
E - Roar of the Slayer
IT'S A JUNGLE SION BUFF : ⇒ Knocked back minions are no longer invulnerable to damage while in flight but can't be killed before landing unless Sion casts Smite on them
COST : 25 mana at all ranks ⇒ 35 mana at all ranks
