The Cave

guide

Home of the Minotarchos, the map's minotaur miniboss — slaying it rewards the Artifact of the Strong, the last of the four artifacts the Hydraskos tribute requires.

The entrance is at 91.1 / 74.0, in Pyranthos. Unlike the map's other artifacts, this one is earned in a fight, not picked off a pedestal.

Hazards

The Minotarchos itself — this is a boss arena inside a cave, not a crawl past spawns.

What You'll Be Dealing With

assembled from what lives in this cave 1

Heavy carnivores

Minotarchos — A boss, not a spawn: massive melee swings and charge attacks in an enclosed arena. It is torpor-immune and rewards its artifact only in death.
Treat it as a boss fight — bring a team of mounts, not caving gear.
