I went duo tribrid DKs tonight with flyguy05200 cuz we both had full slayer helm and a task :P was pretty fun, with the slayer helm its entirely possible to duo tribrid if you know what we're doing, we only got spawned on twice by rex and never by supreme or prime. Not much in the way of loot, got a seers ring second to last kill, and about 2m in tallys and yew logs.
