In my experience it only happens if you kill hatchet while he is "FD" caught in a trap for like 20 seconds.
hello all, Working 2.5 clears for NEC. So I am dragging him across traps where he gets caught (sometimes). But I am still unable to get him below 75% or so HP. He is fully de- buffed. Am I screwing up the mechanics of the raid, or is my tank pet causing problems? Thanks for any pointers or advice. DR kane
Once you have him positioned over a trap you need to click the trap to make him fall to the ground, that will be when you unlock his hp & can do some more damage to him.
