Abilities & tips
Open an ability to read its effect and a practical use tip.
PGlory in Death
After being killed, Sion will temporarily reanimate with rapidly decaying Health. His attacks become very rapid, heal him, and deal bonus damage based on his target's maximum Health.
Practise the hit area and target conditions first. Do not spend the rest of your rotation automatically when the opening damage misses.
QDecimating Smash
Sion charges a powerful swing in an area in front of himself that will deal damage to enemies when released. If he charges for enough time, enemies hit by the swing will also be knocked up and stunned.
Practise the hit area and target conditions first. Do not spend the rest of your rotation automatically when the opening damage misses.
WSoul Furnace
Sion shields himself and can reactivate after 3 seconds to deal Magic Damage to enemies nearby. When Sion kills enemies, he passively gains maximum Health.
Match the protective effect to the moment damage arrives. Read who it protects and how long it lasts before relying on it.
ERoar of the Slayer
Sion fires a short range shockwave that damages and slows and reduces the Armor of the first enemy hit. If the shockwave hits a minion or monster, it will be knocked back, damaging, slowing, and reducing the Armor of all enemies that it passes through.
Practise the hit area and target conditions first. Do not spend the rest of your rotation automatically when the opening damage misses.
RUnstoppable Onslaught
Sion charges in a direction, ramping up speed over time. He can steer his charge slightly with the mouse cursor location. When he collides with an enemy he deals damage and knocks them up based on the distance he has charged.
Use this control to create a follow-up window. Check the target’s defensive spells and your teammates’ range before committing.

Game plan by role
Sion · Top
Keep trades short until you understand the opponent’s main cooldown. Check the minion wave before chasing and preserve a route back to your tower.
Decide between a side-lane push and joining the next objective. Push only as far as your vision and teammate positions allow.
Agree on your job before the fight: pressure a side, threaten a target or protect a carry. Save a key defensive tool when the enemy can turn on you.

Matchup preparation
Compare opponents in the build for the role you are actually playing. Then check their key control, escape and defensive spells before choosing your trade.
07
Practice checklist
- Cast each ability alone and identify its range, target conditions and stopping point.
- Practise the first sequence slowly. Repeat it while moving, without skipping the conditions shown on its card.
- After each attempt, identify the spell you would still have available to defend or retreat.
