OK. He's a nasty mob unless u have a strategy. All u have to do is keep everyone in meeker range and he wont use leash so u only need to.contend with his ale. He also paths up the ramps to the top floor and he spawns at that point so u will have a bit.of a wait when he spawns at a safer camp
This worked great. One thing i would change, get everyone to stand on top of him and move with him as melee and spells push. We started the fight with everyone on top of him, dps pushed him a little bit away from the group, less than 5 or 6 feet and he started chaining people. As a monk it is best not to pull this guy a long distance, i used moving mountains and when he landed he leashed me right back to him fd will break agro but not the dot and he will continue to drag you as he roams around until the affect wears off.
Miggles spawns on the second floor of the temple. His placeholder is a stray goral that roams the 2nd floor. Miggles is non-aggro so you can kill the PH while camping either High Priest Nelori (east side) or High Guard Alsera (west side). His Leashed spell is a DD that pulls the target to him and will interrupt casters.
