Necro - Tanky Skelton Army & Corpse Explosion
Paladin - Zeal / Conviction
Barb - BO
Assassin - Traps and Crowd Control
Sorc - Firewall and Enchant

Get five mercs. Sorc can enchant all mercs, minions (skeletons and assassin shadow), and fellow players. Keep everyone together in a death ball.

Just a fun idea. If you want cookie cutter the more Paladins the better 😅
