Sylas's abilities

Passive, spells and ultimate

Petricite Burst (P)

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.

Playing against Sylas

How to counter and exploit weaknesses

1

If your ult is powerful (Malphite, Amumu, Cho'Gath), wait until Sylas has already stolen it and it's on CD before fighting.

2

Ults that scale with AD are less effective for Sylas since he builds AP — his ult steal is weaker against AD ults.

3

Sylas is relatively weak in early game: punish him before he steals an ult that changes the fight.

4

His E2 is a linear skillshot: side-step to avoid the dash + knockup.
