Crystalline Cavern
An abandoned amethyst mine, and the queen who rules it.
Deep underground lies an abandoned mine still rich in amethyst. The minerals have come to life: creatures made of amethyst defend their caverns, attack anyone who wanders in, and guard their leader, the Queen Slime. The Crystalline Cavern is the one dimension with no level gate and no warp. You get in by using an Energy Crystal Shard, which lets you fight Hellish to Legendary mobs from level 0, if your gear can take it.
Every dimension's level gate, PvP rule and death penalty is compared on the Dimensions page.
Where to Begin
Earn an Energy Crystal Shard from an outbreak in the Wild, then use it to enter. Each shard gets you in once, and dying means you need a new one, so go in with gear that can handle Hellish to Legendary mobs. Using a shard takes you to the Crystalline Cavern Outpost.
The Way In
Getting In
Every 3 hours an outbreak erupts somewhere in the Wild, marked by spikes of amethyst crystal. Find it with /outbreak or jump there with /outbreaktp. An outbreak ends after 150 kills, and everyone who landed at least 10 of them gets an Energy Crystal Shard, a one-time key into the cavern.
Outbreaks look like spikes of amethyst crystal
Why Go Down
In the Caverns
Getting in costs a shard, but it is worth it: you can fight Hellish to Legendary mobs from level 0, long before you could reach mobs that strong anywhere else. It is a great place to farm for the Hunter job, or for gear, until you reach the End. Just remember that a death sends you out and you need a new shard to return.
The Amethyst Throne
Bosses
| Boss | How it spawns | Suggested tier | Health |
|---|---|---|---|
| Queen Slime | Fill the cavern's kill meter (400 kills) | Fatal+ | 13,000 |
The Queen Slime is the Crystalline Cavern's boss, and her arena is inside it. Kill 400 of the cavern's mobs to fill the meter and she arrives. Her summon egg is also sold in the Wild Mission Shop for 100 points, and the Wild's Queen Slime boss mission pays $60,000 and 3 Tokens.
The Geomancer
While you fill the meter, a Legendary-tier Geomancer has a chance to spawn at one of several set spots around the caverns. It casts deadly spells, and it is highlighted through walls so you can find it. Each one is worth 12 level points.

Where to Next
The cavern is a shortcut, not a home. Once you reach level 50, the Nether gives you steady grinding without spending a shard each trip.
