Dreadful Harvester

This creature can trigger Goshnar's Taints, which means it can teleport to players, recover its life instead of dying, etc. This creature can also hit critical attacks.

They retarget very often.

All players should use Stone Skin Amulets and Might Rings when facing these creatures, their Critical Hits can be brutal and kill even high level mages in one shot. Shooters should never stand still blocking them and must be moving all the time during the boss fights to avoid their damage.
