Crystal Hollows

The Crystal Hollows 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. This area is partially randomly generated; only the Structures within the cave are randomly generated, with the exception of Crystal Nucleus. The cave tunnels are not randomly generated and are the same across all servers.
In order to access the Crystal Hollows, the player must obtain a . It can be bought for from Gwendolyn in the , or obtained as a reward from completing their offer in . However, upon completing Dulin's quest, which requires Heart of the Mountain 7, the cost of the Crystal Hollows pass becomes free.
The pass grants access for 6 hours, which continues counting down even when not in the Crystal Hollows. 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. 
Crystal Hollows lobbies are open for a limited time before they reset and generate new tunnels. Somewhere between the 17th and 19th day (about 6 real-life hours), the lobby will close, meaning new people aren't able to join that lobby when entering the Crystal Hollows. Even people who are already in the lobby are no longer able to warp people in from outside. The exact time the lobby closes to warps varies slightly each time. Once there are fewer than 4 people left in the lobby, it will reset with a cave-in.
The following messages appear when the lobby is about to cave in:

A few moments later, the server restarts and all players get kicked out and sent to Gwendolyn in the Dwarven Mines.
=== Mining ===
Inside the Crystal Hollows, blocks that are mined do not get replaced by Bedrock, and are instead removed, similar to vanilla Minecraft mining. Blocks can be placed in most areas of the Crystal Hollows. 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 most vanilla ores are increased within the Crystal Hollows.

=== Treasure and Loot Chests ===
Upon mining blocks, there is a small chance to spawn a treasure chest, containing various rewards. These chest can spawn anywhere except near the bedrock wall. The player must aim at the critical particles on the face of the chests 5 times in a row in order to open the chest. 
Loot chests on the other hand can spawn in set locations within structures; these chests can be opened directly with a small time delay and contain about twice the gemstones and powder of what a treasure chest gives on average.
The loot within such a certain structure chest is always the same for all players who open it within that Crystal Hollows instance. However, the amount of Mithril and Gemstone Powder within each slot of the chest varies between players.https://ibb.co/wd0WZkk Chests from mining do not share this property.
Treasure and Loot chests will only contain the loot found within the area. For example, Magma Fields chests might contain , or .
Treasure and Loot chests have a chance to be a rare loot chest, which can contain better drops. If the chest is not a rare loot chest, it will contain common loot.
The possible loot is listed below, as well as the chance of the item being rolled as a drop from chests. 3-6 drops are rolled per chest.

== Structures ==
Each part of the Crystal Hollows has its own main special location, excluding Magma Fields, which will almost always generate in every lobby:
* The Jungle Temple generated in the Jungle
* The Mines of Divan generated in the Mithril Deposits
* The Goblin Queen's Den generated in the Goblin Holdout
* The Lost Precursor City generated in the Precursor Remnants
* 3 Fairy Grottos generated anywhere within the Crystal Hollows
Each of these structures house their respective Crystal. A special task must be completed to obtain the Crystal.
Khazad-dûm is the one location that can spawn in any part of the Crystal Hollows, making it harder to find.
There are also smaller structures which generate in random locations. Examples include:
* A structure which resembles the Deep Caverns, including the lift and the layered structure of the original Deep Caverns island
* A dragon skull from the Spider's Den
* A replica of the Dark Auction
* A miniature version of The Forge including a working forge NPC
* A copy of the pre-Hub overhaul Tavern
A full list of Structures can be found at Crystal Hollows/Special Locations.
Certain structures contain loot chests. Loot chests always generate in the same positions within the structures, similar to Dungeon Secrets. Loot Chests also generate the same items for every player, meaning if a player finds a chest with good loot such as a lot of Gemstone Powder or a Blue Goblin Egg, they can send the coordinates to chat to lead others to the chest.
== Trivia ==
* The Crystal Hollows are internally referred to as the Greater Mines in the SkyBlock API.
* The Crystal Hollows are the only place , , , and (and other blocks) can be mined, however, only drops itself and all others drop instead.
* Ores within a few blocks of the border may not get auto-smelted without .
* Attempting to get into the Crystal Hollows using an will result in the player being teleported out with the following message, even if they do have a valid Crystal Hollows Pass:
*:
* A player cannot claim rewards from the same loot chest on multiple profiles.
