Old Shaking Chest

The Old Shaking Chest can be found in the Dungeon as well as the Cavern Layer and spawns the Elder Slime NPC when a Golden Key is used on it. It is one of the few creatures detected by the Lifeform Analyzer. The Old Shaking Chest can be damaged by enemies but won't be targeted by them. Like slimes, the Old Shaking Chest will bounce around on the surface of water, a direct indication of what is inside.

Skeletron must be defeated in order for it to spawn.
