Cupreous paragon
A cupreous paragon is a jewel of warm copper tones, a twenty-sided icosagon with capacious providence. Installing the paragon in a suit of armour bestows storage privileges upon it (pockets!), allowing up to twenty items to be stowed at any time. Cupreous paragons may be procured in Delos at the Artefact Armour Shop.
A more elite version of this is the luteous dodecahedron paragon.
