Heated Body. A creature that touches the remorhaz or hits it with a melee attack while within 1 meter of it takes 10 (3d6) fire damage.
Bite (1/turn). Melee Weapon Attack: +11 to hit, reach 2 m. Hit: 40 (6d10 + 7) piercing damage plus 10 (3d6) fire damage. If the target is a creature, it is grappled (escape Difficulty 19). Until this grapple ends, the target is restrained, and the remorhaz can’t bite another target.
Swallow. The remorhaz makes one bite attack against a Medium or smaller creature it is grappling. If the attack hits, that creature takes the bite’s damage and is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the remorhaz, and it takes 21 (6d6) acid damage at the start of each of the remorhaz’s turns.
If the remorhaz takes 30 damage or more on a single turn from a creature inside it, the remorhaz must succeed on a Difficulty 15 Fortitude saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 2 meters oft he remorhaz. If the remorhaz dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 3 meters of movement, exiting prone.
No concoctions, maneuvers, or spells
All creatures in this system should have maneuvers or spells. You should add some maneuvers or spells to this creature. If you do so, please make a suggestion on github so I can finish adding maneuvers and spells to all creatures via https://github.com/mlenser/kryx-rpg-issues/issues/9.
