Hello and welcome to my Sion Guide, I let you know that I have 1 million points on Sion, so I kind of have an idea of how Sion works, his weaknesses, his strengths, so I would say I'm an experienced Sion player, what I'm going to show you is a guide about how strong Sion can become by scaling his Hp with Hp scaling items, making you become Unstoppable Behemoth or become a Killer Assasin with high burst lethality items, or become a Guardian Protector with utility-based items. The guide will be updated whenever I have free time, I will try to learn as much as I can to help you master the Undead Juggernaut.

+ Very Tanky mid to late game
+ Can Turn Teamfights with a single ult
+ Can survive laning phase if played safe enough
+ Scales very well with hp scaling items
+ Can be played as Support and still do well
+ Pairs well with other CC champions
+ Very mobile with Deadman plate
+ High burst damage with lethality
+ Unstoppable if snowballing

- Can lose an entire team fight by missing ult
- Doesn't do so well against a sustained champion
- All of his abilities can be dodged
- Heavily team reliant
- Hard to master
- Requires to have a lot of patience when behind
- Passive can mostly be ignored
- Can't stop Nexus backdoors by himself
- Q Channel can always be interrupted sometimes

You lock in Sion and you are watching their team comp and your own team comp and you start thinking do we have enough damage? or do we need a tank?.

When to go tank:
when you see that your team lacks any sort of defense and you have a hyper squishy carry that needs your meatshield to be successful in battles, if you don't see any tanks in your team or beefy champions go tank, now you should also consider the other team as well if the enemy has a comp that struggles against tanky targets you go tank to make their life harder, overall when in doubt go always tank if you are not sure about their team comp after all you are a tank champion.

When to go ad:
Now, this is for professionals only, so when to go ad? you go ad when you see your team lacks any sort of burst damage access and already have a tank champion like Taric, Thresh, Blitz, to protect you and tank for the team already, you don't want to see too many tanks that won't deal enough damage to kill, so as for the enemy comp, you see them lock in Vayne, Fiora, Kayle, Master Yi, any sort of champion that ignores your resistances, there where you hit the lethality sion, to punish these champions for picking them against you, so whenever you see a tank killer champion, go Full lethality ad, if they want to shred your tankiness, with ad you will make them regret their decision.

1. Corrupting Potion, take this with the sustained runes, the second rune page with warp tonic, it will help you stay healthy in the laning phase and escape ganks much easier thanks to the warp tonic, don't overuse it in lane try to trade carefully cause you will not be so tanky as other starting items.

2. Doran's shield, this is a very good starting item for Sion, take it with the first rune page the one with tenacity, you can trade well with it and also get some health back from being attacked, doubled against a ranged enemy also good ve poking matchup but I found it better for tough short trades, the extra 80 health might help you survive.

1. Mercury Treads, so you get these types of boots mostly for the CC, if you get these just for magic resist it won't make a big difference and combined with legend of tenacity you will have a ton of crowd control resistance, take this for champions like Teemo Top, Amumu Jungle, Mid Malphite, ADC Ashe, Support like Alistar to reduce his E stun.

2.Plated Steel caps, take this if the enemy has no form of hard CC, so in other words, auto type of champion, it will block 12% of their attacks, that's a big deal just make sure that they are an auto-based champion, like Yasuo mid, Draven bot, Jax Jungle, Top Quinn, and poking support like Senna.

1.Frost Fire Gauntlet, Mythic will increase your health and also size, and you burn them with your max health and that slow is huge to land your q.

2.Gargoye stone plate, Huge Hp shield that scales very well, and passive good to keep you alive in battles, the best way to use the active, is when they are using a one-shot ability and you will block it, or just use it if they are melting you.

3.Sterak is strong now it rage restores your hp current to your max health and the shield scales with your bonus hp.

4.Omen is good now from rock-solid passive, it reduces their damage with 0.5 of your max health so hp scaling is good for this, and the active reduces the critical damage and also attack damage by 10% for some seconds, the slow from it is also huge to disengage fights or stick them and land Q better.

5.Titanic Hydra scales with Sion's Hp so his basic attack will extra physical damage from your current bonus health.

(issues)
the only thing about this build that is quite expensive and to work very well all of these items need to be bought so you can make use of them.

(helpfulness)
just keep in mind that all of these items scale with HP so the more HP you get there more you are upgrading all of these items.

If sometimes you need immediate armor and magic resist as first items this is the build you need to get.

1. Deadman plate, position in this game is very important, and the Deadman plate provides that, Deadman provides that slow with the auto to help you land a full Q, and you will be surprised that you can easily escape with Deadman Plate when you see fights that are not in your favor.

2. Visage, is good also against AD teams, that extra regen you get after being attacked will give you enough survivability to resist poke damage, and if you have healer support you will get extra heal by him/her, and the shielding effectiveness is a good thing on sion.

3.Sunfire Cape got change and now it's immolation it's only reason to keep this to the item hp scaling list.

4.Thornmail, a good combo with Sunfire cape if you are one of the Sunfire cape users, but overall reduces the healing and you can easily kill an ADC if you are both fighting each other, just that he mustn't be fed if he's behind you can pretty much auto him/her to death, take this mostly for the healing reduction less healing power can make a big difference.

5. Warmog I get this item for last cause usually staying healthy late game will make a big difference like when you survive a big fight at their inhibitor and got low and then attacking more and get your health back and pressure them again when you are full health.

(issues) this is quite a standard tanky build nothing too special about it

(helpfulness) with the early tankiness thanks to Deadman plate and Visage with boots you can pretty much finish games with only those two items, very roaming potential, I've got rewarded for roaming king so many times thanks to the speed of Deadman Plate and you can head up back to lane very fast which means more XP and farm.

1.Locket Solari, the mythic passive grants armor and magic resistance to nearby allies, and a huge shield that depends on your ally level, this a big deal for support

2.Pauldrons of white rock, well this is far the best of all 3 support items for Sion it has some damage and health and executing minions for that extra 15 health if its a cannon minion remember to save some execution stacks for the cannon minion. You can put it the 5th slot

3. Knight's vow is probably the first item you will build after mythic, it gives that healing for Sion that comes from your adc's damage, and protects your ADC redirecting the damage they get to you, peeling harder for them and that extra armor and movement speed to position your self better with your abilities when you see your ADC getting damaged use shield so damage will go on the shield and you will still heal if your ADC is attacking while the shield is on.

4. Mikael Blessing, this item makes Sion as Support more useful, if you notice they pick an enemy Ashe, rush this item, you will see that just the presence of this item in your inventory Ashe will never ult if she knows that you have it, you can also cast it to yourself and heal your adc too, Use wisely some cc is irrelevant to cleanse, use it to key stuns.

5. Zeke's Convergence, this item is huge for Sion, after you immobilize the target while you accomplice your ally, your ally's basic attacks and abilities deal magic damage plus 1.5% of sion max health so your health is increasing your ally's damage.

(issues) these items to be effective need to be built all of them I know they are going to be a lot of buttons to press, but just position them in your most comfortable spot, they should be 5 buttons to press, knight vow you can put it to 5th/6th slot and use it once, same as Zeke.

(Helpfulness) Reaching full with these items make you very useful for your adc, with all the utility you have damage redirection, armor magic resistance bonuses, shield, cleanse healing, warding, and also ally damage amplifiers.

1.Frost Fire Gauntlet, Mythic will increase your health and also size, and you burn them with your max health and that slow is huge to land your q.

2. Frozen Heart, Very good against physical damage, just lacks health, but you will soon get hp when you farm, the 15% attack speed reduction can really make a difference to those auto-based champions, Rock solid passive huge deal for resistances

3.Omen is good now from rock-solid passive, it reduces their damage with 0.5 of your max health so hp scaling is good for this, and the active reduces the critical damage and also attack damage by 10% for some seconds, the slow from it is also huge to disengage fights or stick them and land Q better.

4. Thornmail, using this item combined with other armor items will make healing based champions life harder, it applies also 60% of grievous wounds after immobilizing targets. pretty good deal.

5.Gargoye stone plate, Huge Hp shield that scales very well, and passive good to keep you alive in battles, the best way to use the active, is when they are using a one-shot ability and you will block it, or just use it if they are melting you.

(Issues) Yes, you going to be very tanky but you will lack health so you will need to work harder on farming and getting assists and kills, late game you gonna get about 3200 hp, not the best hp you want to have, also this build path will not work against true damage max health damage-based champions, you will die so quick against mages, and true damage champions, meat shielding is the only way with this build

(Helpfulness) this build will give you a lot of resistance about 500 armor so you can easily 1 vs 3 ad champions and survive all they put against you, you will be hard as Malphite, but your shield will also be part of your mitigation, and you will able to spam that shield to mitigate most of the damage and peel hard for your carry. 1 vs 1 Trades against any ad champion will be easier than you think, Black Cleaver might reduce the armor to a percentage but it won't totally go low.

1. Grasp, work very well with Sion, you deal magic damage current to your max health and get a juicy 5 hp back and heal too, so more hp more damage and heal.
2. Bash shield, so it gives new shield amount and deals damage currently to your max health so more hp the more damage.
3. Conditioning, Helps you to stay alive in burst situations
3b.Second Wind Helps you resist more poke damage in case if they are just wounding you slowly and regenerates your health current to your missing health, so means the more hp the stronger the regen
4. Overgrowth very good rune for Sion you can stay in a lane doing nothing and you are still stacking up hp, and the bonus after a certain amount gives you an extra percentage perfect to synergize with your abilities.
5.Tenacity, just for that extra resistance of CC so you can position yourself better in fights.
5b.Boots of lucidity, you will save gold for boots and have that extra speed to reach up ranged enemies.
6. Coup de grace, with this you can one-shot low health opponent combining with the titanic Hydra,
6b.Warp Tonic, against a ranged enemy you will need the sustain from corrupting potion to survive the laning phase and that extra speed to reach them.

1. Guardian, with this shield that scales current to your health, will protect your ADC more and haste them to safety, so the more hp the bigger shield.
2. Font of Life, so you will heal your ADC with a percentage of your max health, so the more hp the more healing
3. Conditioning, Helps you to stay alive in burst situations
4. Overgrowth very good rune for Sion you can stay in a lane doing nothing and you are still stacking up hp, and the bonus after a certain amount gives you an extra percentage perfect to synergize with your abilities.
5. Boots of lucidity, you will save gold for boots and have that extra speed to reach up ranged enemies.
6. Cosmic Insight Is a very utile rune for support for item cdr.

1.Prowler's claw, good item to reach your targets after you die, don't use the active when alive if you are not sure that you are going to kill, you might die and regret using it while alive, using in passive mode is a better way, it gives that extra 15% damage after you use it and a ton of lethality combined with other items.

2.The Collector, you will be surprised how many execute you will do to low health targets, this item makes your Q deadly to squishy targets, who knows you might kick one or two also.

3.Ghostblade, good map control item, and also gives you an escape or a small reach to the enemy take this item for map pressure, 6 seconds speed boost active, and 40 ms out of combat.

4.Serpent's Fang, this item is pretty a big deal against lulu Janna Taric, Yuumi, any shield caster will take a ton of damage with this item take this if you see that enemy shields are giving you trouble.

5.Serylda's grudge, Good armor penetration item, if you noticed them tanks, you can hurt them more with this item, 30 armor penetration will tune down their armor and the 1 second slow might help you stick to targets better.

(issues)You become an Assasin, not a tank, so peeling is not effective, ulting over and over might lead you to many deaths, you might deal a lot of damage but if you miss everything you are just gonna die cause you don't have anything to back it up just a few mistakes can lead you to death.

(Helpfulness) You deal high damage so targets will not ignore you, you can carry team fights with the damage output you deal even after death, you will find deaths rewarding if played well.
