Underworld

Intro

The world of Mystera is made up of many floors, with the surface map of Galebrook being floor 1. Directly below is floor 2, the Underground, and below that is floor 3, the Deep Cave. These floors can be reached by building stairways.

On the Deep Cave floor you can find an existing hole (or dig one of your own with a shovel) to enter the Underworld, which spans floors 4 to infinity. Each floor is generated when first reached by a player, and then resets every seven days.

Each Underworld floor is a labyrinth of rooms and tunnels with destructable walls. You cannot build stairways in the Underworld, however you can use a shovel for a chance to dig a hole to the next floor down to speed your descent.

The types of monsters found are more dangerous as you descend deeper into the Underworld; however, gem rocks, altars, skeletons of dead players, statues of mercy, chests and more can be found in greater and greater concentrations.

Exiting the Underworld

While each Underworld level is linked by generated stairways, there are no stairways exiting the Underworld itself. Nor can any be built; in order to leave the Underworld you must: use an escape rope (while on the topmost Underworld floor in order to reach the Deep Cave floor and leave from there), use an Escape Lantern, or find a Statue of Mercy.

Escape ropes are crafted, and allow you to travel up one floor each before being consumed. Statues of Mercy are interactive objects that can spawn on all Underworld floors that will teleport you to the surface at the Crossroads or your current Recall Tile. Escape Lanterns, dropped by Flame Demons and Dust Devils, do the same unless you are bound to a Recall Tile.

• Escape Rope: 20 tinder, 5 silver.
• Recall Tile: 1 dragon scale, 1 escape lantern, 10 gold

Recall Tiles can be built on the surface and you can walk on them to bind yourself to one of them.

Underworld Recall Tiles

There are also (different) recall tiles in the Underworld, which can randomly spawn on all Underworld floors like Statues of Mercy and other interactive Underworld objects can. If you walk on one you become bound to it and can teleport to a random location on that floor using a Depth Recall potion, significantly shortening return trips to the Underworld.

This does not overwrite any Recall Tile on the surface you may be bound to, however; or visa versa.

Exclusive Spawns and Items

Objects

	Chest	Spawns loot of quality that scales with your questing level and the current floor of the Underworld.
	Dark Chest	Spawns a piece of gold, a Watcher, Skeleton Lord, and a Chaos. If the server is currently full on Chaos spawns, then a Reaper will spawn instead.
	Crystal Rock	A rock when mined can yield gems which are used in Smithing.
	Bone Pile	If a player dies in any way, their remains can be found on the same underworld level as their player level was when they died.
	Table	Created for the monsters in the underworld to dine on. Destroy it for wood and more spawns. No, a player probably did not place it and you're not stepping on anyone's toes by destroying it.
	Altar	Can be used and will do one of these things randomly: multiplying items, making you hungry, fully restoring HP and hunger, spawn a random creature, excluding bosses, nothing or disappear. Infamous status can also be drained by dropping gold facing it.
	Glowing Altar	Renames equipment for gold (free for Supporter) See Altars for details on melding equipment runes and traits.
	Fountain	Fully restores HP. Number of uses is random.
	Statue of Mercy	Sends the user back to Crossroads or their Recall Point.
	Underworld Recall Tile	Reminds you of your position in UW. By using a Depth Recall potion you are able to start at last stepped recall tile.
	Firepit	Can either be used (drop 1 wood) to cook meat dropped by mobs or destroyed to gather charcoal, stones, and flint from it.

Traps

UW traps are invisible and not detected until stepped on, triggering their effect.

• Mud: Slows you for -800 movement speed. Move around or use Caraway (+100 each Caraway) to get rid of the slow.
• Pitfall: A hole opens up to the next floor below; more likely you'll fall in the next floor than not.
• Spike Trap: Deals some damage in percentage of your health (25%) when stepped on. Will deal only 1 damage if you're currently Shelled.

Items

Sometimes found in chests.

• Blunt Dagger: A comparatively weak weapon.
• Dark Hero Platemail: Heavy armor.
• Dark Memento: Assassin/Destruction accessory.
• Leather Armor: Medium armor.
• Strange Device: Item that works like a tobacco pipe but drains health and food bars.

Crystal Rock Yields

	Stone	55%
	Gems	20%
	Flint	10%
	Hematite	7%
	Malachite	4%
	Cassiterite	3%
	Silver	0.7%
	Gold	0.3%

Object Spawn Mechanics

Each floor can house a certain number of spawned objects (rocks, altars, fountains, etc.), and once that number is reached, little more will spawn. However, if you break a table, mine a rock, use up a fountain, or otherwise remove something which was spawned, another item can spawn. This does not account for what was used up, meaning that a destroyed table can yield an altar and a used up fountain can yield a regular rock elsewhere in that underworld level.

Monster Spawns

Monsters of any level can spawn at any point in the underworld but will typically stick to the floors outlined in the table. This is a result of abnormal spawns from altars and the "rare spawn mechanic" which will occasionally place a monster from many floors deeper in the underworld in a more shallow floor.
