pretty simple fight.
The whole raid force will have on them an incurable arcane & noxious the whole fight.
There is a Curse that the healer must cure and every about 20-30sec is always a trauma ae that the healers must cure throughout the fight.
There will be a big black bubbling circle that appears but the raid force gets a emote warning "A poisonous fog begins to appear". It can spawn anywhere so have the raidforce clumped up. (like the group instance that black hole of death) only difference its bubbling.
(have joust spots or have someone on the lookout of where it is at depending where the circle spawns.)
75% = 3 adds spawn Kyris, Badum, and Yurit (you want to kill K & B first before Yurit). From what i heard you can mez Yurit till the first 2 add names are down.
25% = (just for safety ae avoid all groups) because another add will spawn "Bone Golem Destroyer" move it away from the name across the room which is better and max range it. (THERE WILL BLACK CIRCLES THROUGH THE WHOLE FIGHT TILL THE NAME IS DEAD) Once it is dead then "A healing totem" at random on anyone at anytime will hit.
Have everyone make a macro "/target A Healing Totem" only ONE PERSON WILL HAVE A VISION TO TARGET hit that macro and everyone will have to target him/her to kill the totem.
Once thats down then kill the name with whatever is left of the hitpoints.
