I missed that multiple stomachs got brought up. Free action to move a prey down is enough for me. Glad I mentioned it to find this out. Gives me the chance to make room at the last minute. :V<br/><br/>Fast healing is regen. Unless regen has another meaning in 5e. Gain <Value> HP per turn. The feat is in short "Recover 1 HP per turn, for each prey alive and digesting during combat." I'd put them together myself even in Pathfinder. Having a spellcaster cast from inside your stomach is such a niche thing. Belly Absorption is pretty much a tax to reach Essence Absorption and Power Overwhelming. Or just cut Belly Absorption as a prerequisite because 5e doesn't do feat chains.
