Optimizer doesn't allow Dark Goblin hunter to show but is the last member of the team and extremely easy to get. Block Revive is Key so it is extremely important to have a dark goblin hunter with a block revive aoe or an earth goblin juggler. The boss and the enemies are all pretty beefy so it will take some time on auto to bring them down. Triggering Poison is also very important so make sure to setup to target the water Holy Sisters first and put 3 on the boss. All roles are crucial for this to work. the treants and shamans place poison, water treant explodes poison dealing major damage while fire treant heals. Revive from water shaman makes sure everyone can last while air shaman triggers the block revive from either Dark Goblin Hunter or Earth Goblin Juggler more often.
