Active:Trundle projects a pillar of ice at the target location for 6 seconds, knocking back everyone directly over it 225 units on cast, acting as impassable terrain for the duration and slowing enemies around it.
Pillar of Ice cannot be placed inside impassable terrain. Attempting to do so will cause the pillar to spawn in the nearest available spot of accessible terrain, similar to wards and pets such as Caitlyn'sYordle Snap Trap.
Pillar Of Ice used to deal 1 damage for it to trigger in-combat effects (such as drawing turret aggro and cancelling the effects of out-of-combat abilities such as Strut and Perseverance) but this is no longer the case.
Pillar of Ice is able to interrupt both ally and enemy Recall.
Active:Trundle drains the life force out of the target enemy champion, dealing magic damage each second for 4 seconds, healing for the premitigation damage dealt and stealing 40% of their armor and magic resistance. Half of the total damage and stealing is applied instantly, and the other half is applied over the next 4 seconds.
Initial Magic Damage:
10 / 13.75 / 17.5% (+ 1% per 100 AP) of the target's maximum health
Magic Damage Per Second:
2.5 / 3.4 / 4.4% (+ 0.25% per 100 AP) of the target's maximum health
Total Magic Damage:
20 / 27.5 / 35% (+ 2% per 100 AP) of the target's maximum health
