Active: Maokai smashes the ground and sends an arcane shockwave forward, dealing magic damage and slowing enemies hit for 2 seconds. Enemies directly around Maokai take the same damage and slow, and are also knocked back.
Active: Maokai transforms into a cloud of arcane energy, becoming untargetable while quickly travelling to a target enemy. Once Maokai reaches the target, the target takes magic damage and is rooted in place for a short time.
Active: Maokai hurls a sapling to a target area, dealing magic damage on impact. The sapling becomes implanted in the ground, granting vision of its surroundings for up to 35 seconds. After a 1 second delay after landing, the sapling will seek out nearby enemies. When an enemy approaches, the sapling will chase for up to 2.5 seconds and explode in an arcane blast that deals magic damage to enemies.
Toggle: Maokai creates a great vortex of natural energy on a nearby area reducing non-tower damage done to allied champions in the area by 20%. Maokai can prolong the effect as long as he has mana to spend on it. When the effect ends the stored energy is released, dealing magic damage plus additional magic damage based off the damage stored to enemies within the vortex.
