As for team building in challenge stage 4, you will need 3 teams. Two of these will consist of AoE Explosive damage dealers with some Single-Target mixed in for the bossing team. Team 3 will consist of AoE Piercing damage dealers to deal with the Heavy armored enemies. Then, bring tanks, healers, and general supports as you see fit.
