After casting a spell, Sylas stores a charge of Petricite Burst. Sylas's basic attacks will expend a charge and whirl his energized chains around him dealing bonus magic damage to enemies hit. While Sylas has a charge of Petricite Burst, he gains attack speed.

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.
