Akuma

Fiendish Blessing. The AC of the cambion includes its Charisma bonus.

Innate Spellcasting. The cambion’s spellcasting ability is Charisma (spell save DC 14). The cambion can innately cast the following spells, requiring no material components:

3/day each: alter self, command, detect magic

1/day: plane shift (self only)

Cloak of shadows: When you are in an area of dim light or darkness, you can use your action to become invisible. You remain invisible until you make an attack, cast a spell, or are in an area of bright light.

Wholeness of Body: As an action, you can regain 45 hit points. You must finish a long rest before you can use this feature again.

Quivering Palm: you gain the ability to set up lethal vibrations in someone’s body. When you hit a creature with an unarmed strike, you can spend 3 ki points to start these imperceptible vibrations, which last for a number of days equal to your monk level. The vibrations are harmless unless you use your action to end them. To do so, you and the target must be on the same plane of existence. When you use this action, the creature must make a Constitution saving throw. If it fails, it is reduced to 0 hit points. If it succeeds, it takes 10d10 necrotic damage.

Deflect missiles: you can use your reaction to deflect or catch the missile when you are hit by a ranged weapon attack. When you do so, the damage you take from the attack is reduced by 1d10 + your Dexterity modifier

Stunning Strike: Recharge (5-6) When you hit another creature with a melee weapon attack, The target must succeed on a Constitution saving throw or be stunned until the end of your next turn.

Multiattack. The cambion makes three melee attacks or uses its Fire Ray thrice.

Spear. Melee or Ranged Weapon Attack: +8 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 7 (1d6 + 4) piercing damage, or 8 (1d8 + 4) piercing damage if used with two hands to make a melee attack, plus 3 (1d6) fire damage.

Fire Ray. Ranged Spell Attack: +8 to hit, range 120 ft., one target. Hit: 10 (3d6) fire damage.

Fiendish Charm. One humanoid the cambion can see within 30 feet of it must succeed on a DC 14 Wisdom saving throw or be magically charmed for 1 day. The charmed target obeys the cambion’s spoken commands. If the target suffers any harm from the cambion or another creature or receives a suicidal command from the cambion, the target can repeat the saving throw, ending the effect on itself on a success. If a target’s saving throw is successful, or if the effect ends for it, the creature is immune to the cambion’s Fiendish Charm for the next 24 hours.
