Merc healer, marksman sniper, and my assassin tank/dps. We were pretty proud of the accomplishment.

Took some time and tweaking but we cleared Dread Palace with 3 people! Pretty proud of that one personally. We all are. Took about 6 hours total to figure out how to pull it off but once we we got it it was over. Gonna try again next weekend for a faster time.
