Crystal Hollows/Special Locations

This page contains details of the locations and structures which spawn randomly within the Crystal Hollows.

Mechanics
Within the Crystal Hollows, special structures spawn in random locations. The structures do not keep their coordinates between lobbies.

There are 5 Main Structures which are guaranteed to generate in the 5 main locations within the cave:
 * The Jungle Temple generated in the Jungle
 * 2 reward chests are in the goal of the parkour.
 * The Mines of Divan generated in the Mithril Deposits
 * The Goblin Queen's Den generated in the Goblin Holdout
 * 2 chests are here: one at the bottom-southwest of the entire structure, one on a wooden platform in a space with the entrance at the north.
 * The Lost Precursor City generated in the Precursor Remnants
 * Khazad-dûm generated in the Magma Fields

Each of the 5 main structures houses their respective Crystal. A special task must be completed to obtain the Crystal.

Sometimes, possibly due to a bug, the Jungle Temple, the Mines of Divan, and the Lost Precursor City may fail to spawn, as well as the Jungle Temple may overlap with other structures, causing the parkour to be unbeatable.

Certain special structures are also guaranteed to spawn in each server:
 * The Goblin King Tower in the Goblin Holdout
 * The Jungle Village in the Jungle
 * 3 Fairy Grottos anywhere within the Hollows
 * Only one will have the zone name, which allow fishing up from its water.

Treasure chests generate in some of the structures. Similarly to Dungeon Secrets, they always generate in the same places. See Crystal Hollows for a list of possible loot.

List
Certain structures can generate anywhere within the Crystal Hollows, whereas some structures can only generate in a specific region.

Trivia

 * There are non-random structures generated as a part of the tunnels. Those structures may look like special locations as listed above at first glance, however they don't have any special properties, nor do they contain chests.
 * Prior v0.19.4, "Palace" was the best type of grotto for jasper mining, which is then surpassed by "Mansion" variant due to the change of Gemstone drop amount from the Glass Panes.
