Hall of mirrors is a 3 man instance. It also doesn't really need a loremaster to complete; therefore I've never actually completed it (it's rare for people to be doing HoM groups and unheard of for them to be asking for an LM). I've wandered in there many months back when moria was new and shiny with fox and ruthilen, but without knowing how to actually do the instance we wiped somewhere near the end.

Wouldn't mind giving it another go. Not after any specific loot, just more because it's an instance I haven't done to death

also not done it, and being a completionist i'd like to get it wiped off the to do list

if u need tank/hunter gimme a shout
