A large collection of items rises up, forming into a swirling chaos that is the body of this being. The items move about throughout its bulk, somehow not touching one another in their mad dance.

The amalgamation is a special creation used by certain ancient spellcasters to defend their hordes and treasure vaults – for even should the guardian fall, most of the items being guarded would b e destroyed, and hence not fall i n t o enemy hands. The creature is composed of a large number of magical and mundane items, and it can use any of them to attack. Because of its magical nature, the amalgamation can even wield magic items such as wands without penalty. The amalgamation resembles a vortex or cloud of items 20 ft. in diameter, swirling within a shimmering field of energy. The precise appearance of the construct depends on the items that comprise its bulk.
