Casting an ability grants a stack of Petricite Burst for 4 seconds, up to 3 stacks. Whilst Sylas has a stack of Petricite Burst, he gains bonus attack speed.

Sylas' next basic attack is modified to whirl his chains around him, dealing magic damage to his primary target, and magic damage to nearby secondary targets.

Damage to secondary targets executes minions below a certain amount of health.

The empowered attack applies on-hit effects to the primary target but disables Sylas' critical strikes' bonus damage. Spell effects only apply to secondary targets.

Sylas lashes his chains out, intersecting at his targeted location dealing damage to and slowing enemies. After a delay, magical energy explodes from the intersection point dealing damage.

Sylas lunges at an enemy with magical force dealing damage and healing himself against enemy champions.

Sylas dashes to a location. Sylas can recast the ability to throw his chains out, pulling himself to an enemy he hits.

Sylas steals the enemy's ultimate ability and can cast it freely.
