This miniature obsidian sarcophagus is small enough to be held in one hand or carried in a pocket. The outside of it is decorated with golden skulls that have rubies for eyes.
Upon opening the tomb, a rumbling is heard and felt in the ground, and a massive sarcophagus bursts through the floor and slams on the ground spreading loose grave soil all around. The sarcophagus appears in any space adjacent to the user that can contain it. The large sarcophagus is 5' x 5' x 10'. It otherwise matches the miniature sarcophagus in appearance. It can easily be opened like a chest by whomever opened the miniature sarcophagus. Objects can freely be placed into and removed from the sarcophagus once it has been opened. When the lid is closed, another rumbling is heard and felt, and the sarcophagus slowly digs itself back into the ground. Any grave soil left behind vanishes in 1 minute. No permanent damage is done by the sarcophagus to area it appeared in.
The Tomb can be called upon freely twice each day, refreshing between midnight and 3 am, as long as the Tomb is not called upon in daylight. Calling upon the Tomb in daylight, or calling upon the Tomb a third or subsequent time both exact a blood price. The user must expend a Hit Die to call a Tomb in this case.
