Vault Cave

Vault Cave is a cavernous area located underneath the town of Vault in Angara, and is an optional dungeon in Golden Sun. It contains a treasure named the Vambrace, and a Mimic as well, but the real prize is the Venus Djinni Sap. However, this Djinni must be driven onto the elevated "island" cave exit in northeastern Vault by ringing the town's bell, so that there can be a Djinni waiting for you when you go through the Vault Cave dungeon and emerge out of that exit.
