SuccubusMedium fiend (demon shapechanger)
Telepathic Bond. The fiend ignores the range restriction on its telepathy when communicating with a creature it has charmed. The two don’t even need to be on the same plane of existence.
Claw (Fiend form only). Melee Weapon Attack: +5 to hit, reach 1 m. Hit: 6 (1d6 + 3) slashing damage.
Change Shape (1/turn). The fiend can polymorph into a Small or Medium humanoid, or back into its true form. Without wings, the fiend loses its flying speed. Other than its size and speed, its statistics are the same in each form. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies.
Charm (1/turn). One humanoid the fiend can see within 5 meters of it must succeed on a DC 15 Will saving throw or be magically charmed for 1 day. The charmed target obeys the fiend’s verbal or telepathic commands. If the target suffers any harm or receives a suicidal command, it can repeat the saving throw, ending the effect on a success. If the target successfully saves against the effect, or if the effect on it ends, the target is immune to this fiend’s Charm for the next 24 hours.
The fiend can have only one target charmed at a time. If it charms another, the effect on the previous target ends.
Draining Kiss (1/turn). The fiend kisses a creature charmed by it or a willing creature. The target must make a DC 15 Fortitude saving throw against this magic, taking 32 (5d10 + 5) psychic damage on a failed save, or half as much damage on a successful one. The target’s maximum health is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its maximum health to 0.
Etherealness (1/turn). The fiend magically enters the Ethereal Plane from the Material Plane, or vice versa.
No concoctions, maneuvers, or spells
All monsters in this system should have maneuvers or spells. You should add some maneuvers or spells to this monster. If you do so, please make a suggestion on github so I can finish adding maneuvers and spells to all monsters via https://github.com/mlenser/kryx-rpg-issues/issues/9
