A loot chest is something frequently left behind when a mob is defeated.
A loot chest is striped with two shades of purple, with gold trim and decorative gems. A gold-rimmed keyhole is located on one side just below the gold-trimmed seam.
When a loot chest is clicked on, a small menu appears with a single option to "pick up" the item. Selecting that option transfers the chest's contents to the player's inventory, causing the chest to disappear.
If not picked up, a loot chest will disappear after a short delay.
