Multiple HeroClix sets have included figures on the stylized "Deity Base" which is a cosmetic facelift to the normal black HeroClix dial. Many of those figures come with a pedestal to elevate that character to a higher height on the tabletop or shelf.
Each Bag of Deity Bases includes twelve (12) individual bases that you can place underneath your figures.
