Team Building

Team building for stage 4 is similar to stage 2 of this event, in which team 1 will want to have a good mix of Piercing AoE and Single-Target damage dealers to deal with the boss and mobs. While teams 2 and 3 want to have Explosive damage dealers to deal with the rest of the enemies. Lastly, fill in the rest of the slots with tanks, healers, and general supports as you see fit.
