Are you tired of going ADC and feeling overwhelmed by everything that the enemy team throws at you? You want to play the game, but it feels like it takes forever to scale. Sometimes you die 4 times in lane, and it feels impossible to come back and have an impact on the game.

Well, congratulation, you are reading the right guide. It turns out that ADC Sion will fix all your problems as well as give you a new very valuable view over the game.

For those interested in watching me play, you can find my stream on
Come say hi!

This guide is a work in progress, positive feedback welcomed. Guide will be updated accordingly.

Here is the win streak you can expect to get if you learn to play ADC Sion correctly: Snip.

Why Sion.

First of all, why play Sion in the bot lane, won't he get kited? And if you're going for a melee, why pick Sion over someone else.

Here are some advantages that Sion brings over other champions:

His passive is amazing when built AD. If you go tank Sion, more often than not, your passive can be ignored the longer the game lasts. With AD Sion, when you die, you will kill most enemies in 3 hits or less.

His Q is similar to an auto attack. This is what makes ADC Sion work. Without charging, it has a range of 300. This scales up to 600. For comparison, Lucian has an auto attack range of 500. In terms of damage, using the Q without charging will always deal roughly the same damage as your AD value, which means you'll always at least have an AOE 'auto attack'. At full charge, your AD value gets tripled. This is why ADC Sion always deals so much damage even early game.

His W is a shield with a health scaling passive. For each 10 minutes in the game, you should expect to gain at least 200 health. By 30 minutes, that's 600 extra health. The range on W is 500. If the Lucian is hitting you, you can hit him too.

E is a single target armor shred, or an AOE slow. The slow is amazing to setup your Q.

Lastly, his ultimate allows him to completely obliterate one or many targets. The charge time to reach the full damage is ~2 seconds. Every time that it is up, you can kill someone in the game.

Why Sion bot though? Once you learn to fill the shoes of an ADC, having a support with you allows you to setup your Q. Also being bot means you can kill two people instead of only one which means you get to snowball yourself, snowball your support and effectively stop two people from their team from playing the game. If your jungler also comes for a gank, well you're a Sion, so every time a jungler comes, you will get a free kill.

All of this combined means that Sion becomes impossible to stop when he pulls ahead even slightly. At worst, his kit is still good for the CC it provides, and given the absolute worst, death, he becomes a massive threat that cannot be ignored.

Pros / Cons


+ Really good laning phase.

+ Really good wave clear.

+ Does amazing sustained and burst damage.

+ Still really tanky for an ADC.

+ Scales really hard.

+ Scales really hard with gold.

+ Can build full damage.

+ Really rewarding passive.

+ Snowballs really hard.

+ When you get ganked, you can 2v3 or 2v4.

+ 4v5 games can be won.

+ One shot people.

+ Very safe positioning before team fights start. You're not going to get picked off.

+ Sion is so dumb, he brings everyone down to his level.

+ Has the coolest skin in the game.


- Relies a lot on having a support that trusts you.

- Very aggressive play.

- Very skill shot heavy.

- People don't really outplay you, it's you that will outplay yourself. Use Q badly and the Lucian will probably dash on you and kill you.

- Very very high skill cap. Bot lane is a brutal lane.

- Not suggested if you don't play Sion.

- Ultimate can be countered by walls. It is also easy to miss if used wrong.

Flash is really important just to reposition when in danger, or to get on top of your target to murder them. Usually Flash should be used as an aggressive spell. If you need to flash out of a fight, that usually means you were positioning badly.


Take Ignite if you think you can snowball the game as early as possible. Ignite counters the opponent's heal. You can also take Ignite to counter healing champions like Swain.


Heal is nice in order to turn fights around. Some matchups aren't won with simple brute force. It's a really good baiting spell.


Ghost is like having a second Flash. It gives you a lot of sticking power. It's a very forgiving spell when you realize you are over extended and need to get out of a sticky situation. It allows you to ignore unit collision during fights where you need to run through a lot of units to get to your targets.


Can be taken if you face a team that has so much CC that you won't be able to do anything. You can pop this spell during those nasty team fights.

Very high damage mastery page. Good sustain from pots, a bit of mana sustain which is enough to always be able to Q on cooldown as long as you don't use W and E like a noob.

Stormraider's Surge is a really good keystone. Last season, I would go Deathfire Touch , but Stormraider's Surge seems better to help stick to targets. When you need to adopt a hit and run kite playstyle.

Items Choices

Doran's Ring

Really good starting item. Gives really good mana sustain early on which allows you to fight a lot better.

Relic Shield

Good starting item since it shares minions with your support, allowing you to build a gold lead even if nothing happens. Your support will also have his own gold generating item so they'll be swimming in the riches. It provides fair 2 player sustain. Don't upgrade it, sell it later when you don't need it anymore. Your goal when you only have this item is to farm and get your first two Long Swords as soon as possible.

Control Ward

You need a Control Ward in the bush closest to the enemy's tower at all times if you're going to push the lane. This allows you to charge Q from that bush while knowing they 100% don't have any vision on you. It's also good to have if you're going to get dragon or baron. I buy on average 3 Control Ward per game. Make sure to place it in the center of the bush otherwise it won't spot the wards at the edges of the bush.

Health Potion

If you're leaving the base with an empty inventory slot and enough gold to buy at least one pot, buy some. You lose lane if you get poked and start to lose health. The sustain from Relic Shield is nice, but it's not enough if you're going to be fighting. The gold you spend on pots is never wasted.

If you don't get pots, you can adopt a lamer playstyle were you only fight during all ins. In order to pull that off, you lane in a way to never get poked. If their ADC or support steps towards you, you back off a bit to always be out of their range. This means you might have to give up some CS.

Youmuu's Ghostblade

Core item. Very easy to build early since it is very cheap. If you die, it gives you that extra movement speed boost to catch up to your targets when you combine it with your Death Surge ability.

Phantom Dancer

Core item. Very nice item to have. Makes Sion's attack speed stop being a joke. It fixes his hitbox problems when trying to reach his targets in a fight. Makes 1v1 fights be much easier against assassins. It allows you to take towers much faster.

Statikk Shiv

Oddly enough, this item feels really good.

Blade of the Ruined King

I mostly only take this against tanks. If you don't have this, it takes forever to kill them.

Hextech Gunblade

Nice when you need sustain.

Infinity Edge

Very nice item to have. Boosts the damage from your auto attacks considerably. Makes it much easier to take objectives like Dragon and Baron.

Duskblade of Draktharr

Can be a nice utility item to clear wards out. Not a must have item. Buy this if you want to be fancy.

Edge of Night

If it turns out that you're the team's primary engage even as an ADC, this item can help.

Mortal Reminder

Core item most of the time if their team has a strong healer. I've lost at least one game in which I can 100% blame the loss on not getting this item. Get an early Executioner's Calling in those games to keep the [ Vladimir, Soraka, Darius, etc] under control.

Titanic Hydra

This items provides a nice auto attack reset that hit like a wall of brick full building made of brick that crushes you.

Trinity Force

Really good item, especially now that they removed the Crit from it and replaced it with attack speed and more CDR. Can be built as 3rd or 4th item usually.

Mercurial Scimitar

Really good item to have if the enemy is able to control you. Also makes it harder for the enemy APC to one shot you.

Guardian Angel

Must get item in some games where you already have enough damage and you need to survive fights. This item can be the difference between a win and a loss.

Zz'Rot Portal

Really good defensive item to get, especially when you notice that your team composition isn't able to reach towers to take them down.

Mercury's Treads

Get this if you don't want to deal with their ******** CC or if you think you need some extra MR. Or if you just feel like building it 'cause why not. Usually a pretty good pair of boots and that's an understatement.

Ninja Tabi

Blocks 12% of the damage from auto attacks. That can be a pretty big deal.

Elixir of Wrath

You're full build? Get this.

You're not full build and you're going to leave the base with 1k gold perhaps? Can't complete an item, and you're likely going to team fight soon? Get this.

You pay 500 gold for a temporary effect that gives you a boost for 3 minutes that is worth at least ~2 times its cost (Give or take). It also gives a bit of sustain against champions, something that you don't get from this build.

The Black Cleaver

I used to think this was a cheaper Trinity Force. Turns out it's just a better Mortal Reminder when the enemy team doesn't have much [healing / life steal].

Death's Dance

I've built this item only once. The healing felt hard to notice. Gives good AD, so I'm sure it can be a good pick up instead of Youmuu's Ghostblade maybe.

Ravenous Hydra

Nice item when you want lifesteal and AOE damage. In most cases, you'll want something else, but if you have the gold, can be fun to build.

Guide Top

Build order

Game start

You can also start with a Relic Shield if you don't expect to do anything before your first back. An other start you can look into is Doran's Ring, especially if your support is likely to be roaming a lot.

Your first goal is to work towards a Youmuu's Ghostblade. If you get a really good early game, you can grab an early B. F. Sword. Sneak your Boots of Speed when you have spare gold.

Second item is Phantom Dancer followed by your tier two boots. Berserker's Greaves if you want to be greedy. Mercury's Treads if you don't need the extra attack speed and would rather have Tenacity and early MR. Ninja Tabi against auto attack heavy teams, or if you need early armor. Boots of Swiftness for extra mobility.

At this point, try to notice how the game is going. If they have a healer champion, you can pick up a single Executioner's Calling. You don't need to complete it until much later.

If the game is going really well, start building an Infinity Edge otherwise, Trinity Force is the way to go. Most games, you can build both of those items anyway.

Round up your build with Mercurial Scimitar or Titanic Hydra.

This is just a draft, this section needs to be more detailed for each support specifically.

With Sion ADC, you get to play with a support. It's really nice since his kit is pretty much designed to fight in 2v2 fights. The best synergy is with supports that help him setup his combo.

Personally I prefer to team up with champions that deal AP burst damage like Annie, Vel'Koz, Zyra, Sona, Morgana, Lulu, Nami, Brand, Karma.

When teaming up with tanky supports, you need to trust your support a bit more since mistakes usually end up in you or them being dead. Blitzcrank, Taric, Thresh, Leona, Alistar can usually do good, but you need to be a good leader.

If you team up with a Janna or a Soraka, it's a bit harder since they tend to be the ones that can set the lane's pacing. With them, I always tell them the following: In this lane, the only one that is allowed to take damage is me. If you, as a Janna or Soraka take poke, any poke, it's bad. Having said that, I have seen really good Soraka players that were able to aggro switch really well and it really felt like they were doing the carrying.


| | | |
You are two melee champions, so you are likely to get poked a lot early game. If you get pushed in, you might have to give up a bit of CS so ask for an early gank. Really strong duo after the first back if you keep buying pots.


| | | |
Really strong lane even before the first back. She is able to do a lot of work for you with her incredible poke. With her Grasping Roots she can setup your Q, or vice versa. Make sure she doesn't get too cocky. If she over extends, the other team can punish her and deal a lot of damage to her. I find that a lot of Zyra players really like to step up close and personal with the enemy team. That's usually bad.


| | | |
Really strong lane, but with a bit of anti-synergy since he can pull people out of your abilities. His Rocket Grab is on a really long cooldown so don't waste your Q before he is about the grab someone.


| | | |
Strong lane, but with a bit of anti-synergy since she can push people out of your abilities with her Monsoon. She is really amazing at protecting you. If you have vision control over the bush you are in, you can cheese a Q + Howling Gale combo to one shot people.

How to play Sion ADC

Early Game

Your first goal when you start the game is to farm to get your first 800 gold for your first two Long Swords and pots. That's your first power spike.

Before that happens, you want to play safe so that you don't die. Try to land your Q on your two opponents. Notice how they react. Does their ADC respect you and backs away when you walk towards him? If he doesn't then you can harass him out of lane. Always mind your own positioning. Sion can get minion blocked really hard.

If they push the lane, you might have to use Q on the minion wave to counter their pushing. Or you can also freeze the lane in front of your tower. You can also your support to help you push if you need.
