Boss mechanics

Telegraphs, adds, totems, soaks and pillars: what each boss does and how to answer it.

How to read a mechanic

A red mark pulses on every tile the hit will land on, from 1.5 to 3 seconds before it (harder content warns later). The hit lands only on the tiles still marked: walk out. There is always a safe tile you can reach in time at normal speed.

Orange warnings name the big casts, and a bar under the monster bar names the next mechanic with a countdown: red = move out, purple = kill the totem, green = stand in the circle, blue = hide behind a pillar.
