Minecraft Dungeons:Chest

Chests spawn throughout a level and tend to have a finite amount that the player can check by viewing the map. There are several types of chests that exist in the game and each chest can give the player gear (with the exception of the lobby chests which only give emeralds).

Common Chest
The regular common chest that spawns in a level that can gives the player emeralds along with: a bundle of arrows, a potion, or random gear that drops in that level.

Fancy Chest
A much more uncommon chest that spawns in a level that drops similar loot as the Common Chest but gives the player a guaranteed gear for the level with a very low chance to get a unique variant of the gear.

Obsidian Chest
A rare chest that spawns in a level that drops similar loot to the Common Chest but has a guaranteed gear drop for the level and an even higher chance to give the player a unique variant of the gear.
