Black Castle: Rolling Boulder when entering the upper floor can wipe those, going thru the door late (like Ardashir Rhino)
Some fights in here can take long - especially last with all the adds and you wont get OOC Regen. this might mess hots and caster dps up and could lead to a wipe when fighitng the boss at mid when adds keep spawning -> consider 1 point in Ether Theft on BS (or light of Mitra, but you wanna spec Vengenance first i guess)
after the fire trap (the one where you need to put weight on 4 plates) - which can 1 shot you of course - remember to fight the eye symbols on the walls near the ceiling or else they can kill you too.
Sanctum: dont get the quest near the sanctum from the necromancer (curse of flies) which would be a prerequisite for another sanctum quest. the quest randomly bugs and can make you get 1 shot by the curse of flies
ardashir arena: 1 shot mechanic on at least 1 boss; some hard fights over all, if you dont know the mechanics - which i dont know all that well ^^
cistern: dog boss stuns for a few seconds, make sure your casters dont get eaten
DT/bomberman boss: the bombs can 1 shot you, places a fear banner at certain % threshold which can make you run either in the bomb or in the poison traps; make sure to kill adds in a bigger radius than you’d normally do before pulling the boss; the gargyles hit pretty hard, so avoid them or activate and kill them carefully. if the layout of the posion traps is bad (they sometimes occupy adjacent squares) you can pull and reset the boss which also alters the layout of the traps
Main System: 2 bosses charm players -> the alchemist boss and the left of the 3 casters in final room. final boss hits like a truck, be ready to kite or pull aggro as non tank
Catacombs: conq boss enrages (lumbering hulk like) which is easy to avoid, but can be dangerous if for some reason an urn gets destroyed and kicks the target of enraged boss -> kill urns before pull.
Activate particles on 2nd last boss (hox), places a dangerous fire pit!
better dont jump over the lava in AoK
