Geomancer

[Archwizard]

The Sai Taisui in Swallow's Compass and Heaven on High using their own Malediction of Water, Malediction of Wind and Malediction of Earth. Being a point blank aoe around the caster, a targeted aoe and I hoenstly can't remember what earth does but I assume an aoe as well.

From Swallow's Compass, the first three Sai Taisui encountered use "Evocations" instead of Maledictions.
Evocation of Water summons water bombs that will inflict Paralysis if allowed to detonate without being destroyed.
Evocation of Earth summons ivy pools under two players that will attempt to damage and root them after a delay.
Evocation of Wind marks two players to place tornadoes at their locations after a delay, which act as continuous hazards.

The next pair and the ones in Heaven on High then use Maledictions.
In Compass, Malediction of Water summons a corridor-wide tidal wave to push players back; in Heaven on High, it's just a damage buff on the caster.
Malediction of Wind centers a ground-targeted tornado under a random player that inflicts Vulnerability Up to any targets inside when the cast finishes.
Malediction of Earth... is never shown. None of the Sai Taisui actually cast it.
