Mark of Consumption

After every short rest the Mark allows you to gain resistance to a specific damage type (Acid, Cold, Fire, Force, Lightning, Necrotic, Poison, Psychic, Radiant, Thunder)

Swallow. Roger uses an action to inhale a medium or smaller target that is within 5 feet of him. The targeted creature must make a DC 15 Strength saving throw or becomes swallowed by Roger. While swallowed, the target is blinded and restrained, it has total cover against attacks and other effects outside Roger, and it takes (4d6) acid damage at the start of each of Roger’s turns. Roger can have only one creature swallowed at a time.

If Roger takes 20 damage or more on a single turn from the swallowed creature, Roger must succeed on a DC 14 Constitution saving throw at the end of that turn or regurgitate the creature, which falls prone in a space within 5 feet of Roger.  If Roger dies, a swallowed creature is no longer restrained by him and can escape from the corpse by using 15 feet of movement, exiting prone.

Spit (with a swallowed creature inside him only). Roger uses a bonus action to spit out a creature he has swallowed at a target he can see within 20 feet. The target must succeed on a DC 15 Dexterity saving throw or take (4d6) bludgeoning damage and fall prone. In addition, the swallowed creature takes (4d6) bludgeoning damage, is no longer swallowed by Roger, and falls prone in a space within 5 feet of the target.
