The Avatar Vault, commonly mistaken as the Character Vault, is a larger variant of a Character Chest. They only appear in playsets. To open these vaults, you need every character for a given playset to interact with it. Once opened, it always gives a Pre-Built Toy Box themed after the playset. It also often gives the Skydome and Terrain Set for a playset. If not, it has other preset toys that it gives out. It also randomly gives out some of the toys that are also randomly distriubuted by the third chest of a given character.
