Mythic Treasure Chest

The in-game count leaves out the gem roll below: a chest can hold one gem more, up to 4 items.

Raised by Gold Find.

One gem roll per chest, on top of the items; the gem is one that drops at the chest's level.

Uncommon 15%, Rare 70%, Legendary 15% before the loot bonus; Rare and Legendary are multiplied by (1 + Item Find) and by the loot bonus of the stage it dropped on. No Legendary from a chest below level 10.

Rolled before the rarity, x (1 + 0.3 x Item Find) x 2 (Solo Self-Found) and x the loot bonus of the stage it dropped on, only for a chest of level 70 opened on Inferno.

In a chest of level 70, a Legendary item (not Back) has a 10% chance to be Ancient; opened on Nightmare or Inferno, a 0.32% x 2 (Solo Self-Found) Black Mist roll comes first.

A chest dropped by an enemy has the level of the enemy killed last in that encounter; each item is equipment that drops at that level, for the current hero's classes.
