Gentlemen,
I will try to add some information which some people already know and some don't. So here we go:
Suggestion 1 (added info to a repost from november):
There is a “hidden boss (gremlin/murlock). He is located in the room where the 2 abominations mobs are fighting. On your left there is a tunnel in the wall, go into the tunnel and clear the trash. Then you will meet Eck. A gremlin/murlock mob. If he hits you with this poison, you get a deburf who can’t be dispelled (but it doesn’t hurt either). The only thing it does, makes you smell. If you kill the last boss and you still have this debuff, you get the achievement “What the Eck!?”
Suggestion 2:
The boss who casts Transformation and turns into a Rhino: Interrupt. You will unlock an achievement if you get it to the boss before turns into a Rhino.
Confirmation of first boss (guildies did it yesterday)
Problem = too many adds with a lot of HP
Possible solution = they can’t swim. So place the tank at the entrance and the caster/healers in the water. What happens, adds stay at beginning of the water. Easy to bring them down.
Thanks
