I hate this NM already.
No idea on latent for the mace.
Seems to be lottery tho, tried to take it out with 2 people 2 boxing (NIN BRD WHM BLM) best we did was 15%. It stays big after you wipe (as previously stated), and stays raged, but it doesn't really have that much HP. Just a pain in the ass to get to.
edit> We didn't kill it with the group of 4, left it up overnight and came back after Faf, and it was not up. Popped after 3 or 4 place holders were killed. So it may or may not depop.. but it was up when we got there the night before so more than likely someone else just killed it. (no drops were posted on the AH tho)
