Treasure Chest

Treasure Chests are objects that spawn randomly within the game world and can be looted for a variety of contents. Chests can be opened with the use button while standing next to them. Alternatively they are destructible using fire, explosives, or spells. When destroyed, their contents will become available as if opened with the use button.

When generating a new area, there are specific locations that can spawn an Extra Max Health or a chest. For each of these places, there's only a $2⁄5$ chance it spawns a chest (instead of a heart pickup, or nothing). If that roll succeeds, $1⁄10$ chest spawns instead spawn a Mimic, and $1⁄1,000$ spawn a Great Treasure Chest instead.

Loot Table
When opened, chests will roll randomly for their loot, which is generated according to the following table. Values in bold are the chance in that individual roll, values in italics are the overall percentage probability out of all other possibilities.

Other Information

 * Wands found in chests can be stronger than those that spawn naturally, especially in the Mines.
 * $1⁄10$ chest spawns are replaced with a Mimic. They can be distinguished by the way they float in water, if they have a stain icon above them, show no Treasure Chest tooltip when moused over or show damage numbers when attacked.
 * If you make it to the Holy Mountain without directly killing any enemies in the area leading up to it, a chest will spawn above the perk altar in the left ceiling alcove. Indirect kills do not count.
 * The contents of the chest is determined by the map seed and the chest's spawn position.

Trivia

 * During Early Access, the contents of the chest would change if you moved the chest around before opening it.
