Summary

Thebausffs
Guide by the greatest Sion player who inspired my item selection for this guide. You can also watch his videos and streams to learn how he plays more extensively.
Below is an essential guide for Sion players, relevant part of the guide is from 10:45 to the end. In the description there is a spreadsheet which explains how to deal with each matchup, although some advice might be outdated.

Basics
One of the most important things to remember is to have a consistently high CS rate so you can be useful. Try not to miss any CS in laning, proxy, take enemy jungle. Don't be afraid of dying, but still learn from your mistakes so you can die for a better reason next time. Being aggressive is the only way to improve. As long as you keep this in mind, you can play inting Sion in your own way.
Try to predict which lane will be the most annoying for the enemy to deal with you in. Make sure to put wards close to towers if you want to

Deciding which build to play:
Tank or AD: This will depend on if your team needs a tank or more damage, as well as how much anti-tank the enemies may have. The spreadsheet in the description of Thebausffs' guide linked above shows which build is better for which matchups. If you're unsure, tank is generally a better pick than AD. AD is not in a great place at the moment.
Best ban: Jax
Items

Core (Tank)
![]() |
This is not an item you have to change your playstyle around much, aside from auto attacking more, which you already should be doing when you have the chance. If you're always dying before you can even do anything, especially if several enemies target you simultaneously, it may be better to take ![]() |
![]() |
Similar to ![]() |
![]() |
Pretty straight forward item. Just don't use ![]() ![]() |
![]() |
Consider spacing out your abilities more to make use of damage over time. This is not a great item, but better than taking a situational item you don't need. |
Core (AD)
![]() |
Essential funny item. Saving the active for during your passive can be wise to get a kill. |
![]() |
Movement speed and lethality choice, can be taken before or after ![]() |
![]() |
You can just build ![]() ![]() |
![]() |
Can be built before or after ![]() |
![]() |
Once you have 40% crit, buy this. If you don't have space for it because you bought a situational item, you can replace boots or ![]() |

Situational (Tank)
![]() |
You should take this frequently. Make liberal use of aura damage when you can. Aura size increases with champion size so keep it in mind when you increase size due to ![]() ![]() ![]() |
![]() |
Don't take this too often, but it's good when auto attack heavy enemies are posing a big problem to you. Make sure to use the aura when you can, either for yourself or to help teammates. ![]() |
![]() |
Similarly to ![]() |
![]() |
If you really need antiheal and this item will work on your target (they have to auto attack you to proc Thornmail). Don't take this too often though. |
![]() |
If their top, mid and jungle are all AP |
![]() |
Vs high CC |
![]() |
Vs lots of auto attackers |
![]() |
Great boots during your passive and for general movement. Take this more frequently than other boots. |
Situational (AD)
![]() |
Take if there's 2 enemies with frequent shields |
![]() |
Take about every game, when it's convenient |
![]() |
If you just need more damage |
Strategy details

- If both teams are busy in a team fight, it's your chance to push your lane! But sometimes engaging in the team fight can be a good idea if you have
Unstoppable Onslaught or
Teleport. It depends on how good the opportunity is, in contrast to the opportunity of possibly taking a tower or two. A good opportunity to do this would be if you've attracted a couple of enemies so you can't destroy the tower anyway, so you can quickly Teleport or ult to the teamfight and easily win it since they are missing members.
- If an enemy is in your lane and you can't deal with them quickly, consider swapping lanes or grouping with your team.
- Don't ult if there is an enemy that can create terrain like
Trundle, since they can block you.
- You can press W before
Teleporting or while using
Unstoppable Onslaught to be able to recast for damage once you get there.
- Your Q outline is invisible as long as
Sion is outside of enemy vision.
- Use E before Q or R to land them consistently.
- The end of R can do a bit (a lot if you're AD) of AoE damage to towers.
- If a tower is being protected, you can proxy behind it. You can also use time between waves to take enemy jungle camps and proxy at their inner towers (as shown in Thebausffs' guide)
- If you
Unstoppable Onslaught at melee range to an enemy, press and hold Q right after pressing R to increase the stun duration and reduce the Ult animation. If you're Ult someone from farther away, recast R before hitting them instead.
Unstoppable Onslaught ignores CC.
- Use
Soul Furnace after someone uses their abilities on you, so you can still block some damage but also get the recast damage off.
- In difficult matchups, contest the wave at very early levels, which will likely lead to your death, in which case you can get some CS and do some damage to the enemy laner in your passive, forcing them to recall when you
Teleport back, letting you fix the wave.
Runes
The extra damage that it deals means you can trade whenever you can use it and usually win! Actually you should have W up to trade, but against tanks you only need grasp to trade. Inting Sion doesn't care much for healing but he doesn't mind it, so ![]() |
|
![]() |

![]() ![]() |
