Crystalline Cavern

Deep underground, an abandoned mine lies still rich in amethyst. With minerals come to life, creatures made of amethyst have formed to defend their lands, attacking adventurers and defending their leader, the Queen Slime.

How to Unlock

Every 3 hours, an outbreak occurs in the Wild which can be found with /outbreak. Outbreaks end after 150 kills and rewards everyone who has acquired 10 kills with an [Energy Crystal Shard], a one time consumable to access the Crystalline Caverns.

Outbreaks look like spikes of amethyst crystal

Death Mechanics

On death, you lose only your inventory. You keep your armor and entire hotbar. Once dead, another crystal is required to re-enter.

Gameplay

The Crystalline Cavern is an expensive dimension to get to, requiring an Energy Crystal Shard to teleport to. This is well worth the price, allowing you to fight hellish-legendary mobs right away at level 0. But be warned, if you are ill-equipped a new crystal will be required to re-enter. This is a great place to farm mobs from the hunter job or for gear until you can get to the End.

Additionally, there is a boss called Queen Slime that only spawns in the Crystalline Cavern by filling the mobs killed meter (400 mob kills) in the caverns.

While you're filling the meter, a legendary tier Geomancer has a chance to spawn at one of the set locations around the caverns. They are highlighted through walls to help you find them easier.
