Minecraft/Structures

Dungeons
Dungeons in Minecraft (not to be confused with the separate game Minecraft Dungeons) are small enclosures made of cobblestone or mossy cobblestone that generate underground. They have a spawner that spawns either zombies, skeletons, or spiders and one or two chests containing rare items. The spawner can be disabled by surrounding it with several torches, broken for XP, or used to set up a mob farm.

Abandoned Mineshafts
A group of underground tunnels with cosmetic wooden supports, rails, minecarts with chests containing rare items, and cave spider spawner. The spawner can be disabled by surrounding it with several torches, broken for XP, or used to set up a mob farm.

Desert Temples
An aboveground structure in deserts made of sandstone and terracotta. It consists of a pyramid and two pillars, all hollow. There is a 3x3 hole in the center of the pyramid, with a blue terracotta block covering the center. DO NOT BREAK IT. There is a pressure plate that activates 9 TNT in the center. Surrounding the pressure plate is 4 chests with rare loot, and the TNT can be taken as well.

Jungle Temples
A cobblestone structure in jungles with multiple floors, some chests, and traps. There is also a lever puzzle, but due to the nature of Minecraft, breaking the wall is an easier way to get the loot. The arrow trap can be disarmed by breaking the tripwire with shears.
