This devotional cask would operate similar to a spellbook case from mystical machinations, where you can TURN the cask to rotate between sections. The devotional cask has 3 sections that work like a keg for carrying stacking volumes of holy water, holy oil and wine (or whatever liquids you'd want to carry) rather than a single liquid like kegs currently work. It would utilize a generally worn inventory slot but you could adjust it to be worn over the shoulder, on the belt, thigh and around the waist. If you had all 3 sections in use it would count as 4 items.
