Minaxxaar

Minaxxaar is the eleventh boss encounter in the Citadel of Darkness. He is located inside the caverns, which are accessible with the Key to the Caverns from the Lightning-Forged Golem.

Strategy
Minaxxaar is a fairly difficult encounter. This boss moves faster than the previous 10, which were all zombies, because Minaxxaar is a spider. This also means you can not make it easier to do the encounter by going on top of a wall.

Minaxxaar is hard to kite, as he moves very fast. The strategy for Minaxxaar is to burn him as much as possible and kill him as fast as you can. There are adds that spawn in this encounter, however, which makes it even more challenging.

The other thing that makes Minaxxaar a difficult encounter is because he has a large health pool. He has 2,570 health on normal mode (3,040 on Legend Mode), which makes him a lot more difficult to slay.

You will want to kite Minaxxaar around the entire boss room, and you may need to sprint occasionally to get ahead of him. Attack him as much as possible, as you need to burn the boss down as fast as you can for this encounter.

Loot
Key to the Citadel Garden - 100%
