Best 3-hero party compositions

Knight + Priest + Ranger (universal early)

Knight blocks 30%+ of incoming damage. Priest passive heal/AD buff sustains the party indefinitely on Normal/Nightmare. Ranger AOE clears Stage waves fast. Switch Priest → Sorcerer when you hit Act 3.

Bat-build for Pet farming

Goal: kill 5,000 Bats at 1-7 City Outskirts where Bat has a 37% spawn rate. The optimal comp: Priest (tank/sustain) + Sorcerer with Fire Hydra maxed (sticky AOE) + Ranger for cleanup.

Boss-rush

Slayer + Hunter + a tank. Both DLC classes have AD-multiplier passives; pair with a tank that draws aggro and they melt Act bosses.
