Greater vaults

Here is an example of a greater vault in the left half of D: 44. It contained fire creatures:

Note that this map displays an almost guaranteed feature of greater vaults - hidden rooms. Directly to the north of the PC is a 1 x 3 space. This was originally a hidden door and a 1 x 2 room containing a monster guarding an artifact, now lying on the floor. To the east is a fomerly secret 1 x 1 room. On the other side of the vault are two additional formerly secret rooms. The three that did not contain an artifact each contained 30,000+ gold pieces.

Greater fire creature vaults are not always in this configuration. The hidden rooms vary in location according to the layout.

This particular greater vault does not contain small hidden rooms, although the doorway into the central chamber is initially hidden.

The hidden rooms in this greater vault are the ones containing the miscellaneous [%(*}* items. There is a very good chance of finding an artifact in the inner room.
