The character creates a construct known as a
living vault to protect and
hide his or her treasures. Upon completion, the vault initially measures only 5 feet on a side, but it gradually increases to its proper size over the following 4d4 days. The vault is attuned to the character, allowing him or her alone entrance and egress in a manner similar to a
dimension door spell. When the character desires the vault to
hide itself, he or she gives it a simple
command. To summon the vault, the character may cast a
sending spell or arrange some other manner to contact it.
