I just tried a dungeon run of Black Fathom depths but we got a stuck in combat bug which wouldn't let me drink to restore mana.

The rest of the group logged and I thought I would see how well I could solo it.I tried one of the huge turtles near the turtle boss and managed to get him down so I figured maybe the turtle boss is solo-able.

I managed to kill it at level 29 , the boss is level 25 elite so I guess with the right spec I could solo some of the dungeons.

This would be a good way to train for the Iron man mode.

Im using the druids regrowth spell, priest renew spell and the shamans healing wave. For mana regen I have the shamans mana totem, water shield and the paladins blessing of wisdom. My main damage spell is the fire mages pyroblast.

I bet if I tweak my gear a little more I could do solo dungeon runs fairly easily.
