The Treasury of Proteus is the quest artifact for the Pirate role, incorporated into dNetHack, Slash'EM Extended, and SLASHTHEM. Its base item is a chest, but it weighs just 150 units--the same as a crystal ball--which is one-quarter of the weight of a regular chest.

The Treasury has the unique property of occasionally polymorphing items that have been placed inside it, according to the rules for polypiling objects. This offers users a means of polypiling items without a wand, spell, or potion.

While carried, the Treasury protects items in the player's inventory from becoming cursed by monster spells (just like Magicbane when wielded). The explanation given for this is that the Treasury itself is so heavily cursed that it sucks in lesser curses like a black hole. (Indeed, the Treasury is generated cursed.) It also grants magic resistance.

The Treasury of Proteus is chaotic for bones and wishing purposes. As a quest artifact, it is intelligent and will blast non-Pirates who touch it.

Origin

Proteus is a god in Greek mythology who is associated with the sea. He is known for his ability to change form as desired, which he often uses to escape mortals who seek him for his ability to foretell the future. Hence the Treasury's property of polymorphing objects entrusted to it.
