Tor gul the defiler

Does little damage, hard to tell what it’s doing.
Unfortunately it’s not really scalable due to this so mechanical changes could be better. Maybe increase the fire aoe range allowing it to completely block off a section of the map forcing you to backtrack through its throw up if it crawls out.

This creates a gameplay element where the boss can kill you by chasing you into his fire due to bad player positioning. Because of this the fire duration would have to increase by a …..certain amount.
