Fiendish power 1.2

You have red eyes, can spawn shadow wing, shadow claws to do some of the effects under. You are starting to look more charming (+2 cha)

 claws: 1d6 slashing damage + dex. 5 feat, dex based melee attack. when you make an attack with your claws you can make another claw attack as a bonus action.

redish eyes: your darkvision increases by 25 feet.

 You get 35 feet flying speed.

Fiends rage: you can as a bonus action surround yourself in black flames.

when you are surrounded by these flames you deal an extra 1d6 necrotic damage on your melee attacks. creatures take damage equal to your charisma modifier when they hit you with a melee attack.

Ones per short rest, when you have the flames activated you can either:

Use an action to shot out your black flames in a 30 foot cone. Each creature in that cone must make a dex save. A creature takes 5d8 necrotic dmg on a failed save, or half as much on a successful one.

Doing this makes your flames go away until the start of your next turn (meaning you dont get the extra necrotic dmg on a melee attack and enemies dont take necrotic dmg when they hit you from this ability until the start of your next turn).

Or

When a creature damages you within 30 feet of you, you can use a reaction to shoot out your black flames to the creature that damaged you. The creature must make a dex saving throw. It takes 4d10 necrotic damage on a failed save, or half as much on a successful one.

if you go under 1/3 of your hp maximum when you have these flames activated you need to roll a wisdom saving throw each turn as long as the flames are activated and you are under 1/3 of your hp maximum.

Dc: 11 wisdom saving throw. If you succeed nothing happens. If you fail you will attack the closest creature to you.
