Chests (WoW)  

Chests are containers found through the world, usually near to humanoid camps, which contain loot when opened. This loot typically contains of food and/or drink, some sort of crafting material (such as leather), and possibly a green-quality or higher item. All chests found in the outdoor world are unlocked, while those in instances can be either locked or unlocked. To open a locked chest, either a rogue with sufficient lockpicking skill or an Engineer-created Seaforium Charge must be used. Locked chests typically contain better loot than unlocked chests. Chests can also be recovered from fishing and may be either locked or unlocked.
