The HungryMedium monstrosity
Life Hunger. If a creature the Hungry can see regains health, the Hungry gains two benefits until the end of its next turn: it has advantage on attack rolls, and its bite deals an extra 22 (4d10) necrotic damage on a hit.
Bite (1/turn). Melee Weapon Attack: +8 to hit, reach 1 m. Hit: 8 (1d8 + 4) piercing damage plus 13 (3d8) necrotic damage.
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.
