MaurezhiMedium fiend (demon)
Assume Form. The maurezhi can assume the appearance of any Medium humanoid it has eaten. It remains in this form for 1d6 days, during which time the form gradually decays until, when the effect ends, the form sloughs from the demon’s body.
Magic Resistance. The maurezhi has advantage on saving throws against spells and other magical effects.
Bite (1/turn). Melee Weapon Attack: +6 to hit, reach 1 m. Hit: 14 (2d10 + 3) piercing damage. If the target is a humanoid, its Charisma is reduced by 1. This reduction lasts until the target finishes a short or long rest. The target dies if this reduces its Charisma below −5. It rises 24 hours later as a ghoul, unless it has been revived or its corpse has been destroyed.
Claws (1/turn). Melee Weapon Attack: +6 to hit, reach 1 m. Hit: 12 (2d8 + 3) slashing damage. If the target is a creature other than an undead, it must succeed on a Difficulty 12 Fortitude saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Raise Ghoul (Recharge 5–6). The maurezhi targets one dead ghoul or ghast it can see within 5 meters of it. The target is revived with all its health.
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.
