Crystal Hollows

The  is a randomly-generated Mining area. It is the primary source of Gemstones.

Mechanics
The Crystal Hollows is a mining area from to, enclosing an area of 621 x 157 x 621. Bedrock walls enclose the mineable area.

In order to access the Crystal Hollows, a pass must be purchased from Gwendolyn. The pass costs and grants access for 2 hours. When the pass is about to expire (1 minute before), it can be renewed by clicking the chat message.

Once the pass is purchased, the Hollows can be entered via the Minecart next to Gwendolyn or the Minecart icon in the SkyBlock Menu. Clicking the Minecart in the SkyBlock Menu while in the Hollows returns the player to the Dwarven Mines.

Every 2 hours (6 in-game days), Crystal Hollows servers reset with a cave-in. Just before a cave-in, the following messages are displayed in chat:

After that, the server restarts and all players get kicked to Gwendolyn in Dwarven Mines.

Mining
Inside the Crystal Hollows, blocks that are mined do not get replaced by Bedrock, and are instead removed. This is similar to vanilla Minecraft mining, ores that require a furnace do not require Smelting Touch to be obtained.

Stone is replaced by Hard Stone within the Hollows, which is harder to break than Stone. Gemstones, Mithril, and vanilla ores spawn within the Hard Stone.

Yields from vanilla ores are increased within the Crystal Hollows.

Treasure
Upon mining blocks, there is a small chance to spawn a treasure chest, containing various rewards. The player must aim at the critical particles on the face of the chests 5 times in order to open the chest. Treasure chests can also spawn in set locations within structures; these chests can be opened directly.

Treasure chests will only contain the loot found within the area. For example, Magma Fields chests might contain, or.

The possible loot is listed below. Multiple (typically 4-10) stacks of loot generate from 1 chest.

Structures
The structures of are randomly generated, other than the Crystal Nucleus and cave systems.

Some structures inside resemble the Deep Caverns that contains the lift and the layered structure of the original Deep Caverns island. Other locations include a dragon skull from the Spider's Den, a replication of the Dark Auction, and a copy of the pre-community update Tavern.
