Vanguard · magic (AP) damage
Maokai is a Vanguard that deals magic (AP) damage and brings airborne, root, slow. Some of their lockdown (airborne) ignores tenacity, so you dodge it; you can't cleanse or Merc' through it. Below is Maokai's highest-win-rate build from high-elo games; open the counter-build tool to tune it against your specific enemy team.

Maokai's basic attack also heals him and deals additional damage on a moderate cooldown. Each time Maokai casts a spell or is struck by an enemy's spell, this cooldown is reduced.

Maokai knocks back nearby enemies with a shockwave, dealing magic damage and slowing them.

Maokai contorts into a mass of moving roots, becoming untargetable and dashing to the target. Upon arrival, he roots the target.

Maokai flings a sapling to the target area to stand guard. More effective in brush.

Maokai summons a colossal wall of brambles and thorns that slowly advances forwards, damaging and rooting any enemies in the path.
