True form of the Nosferatu 1.2

The blood fills your body with power and enhances your physicall body as you transform into a horrendous creature of old nightmares. If you are wearing armor/clothes that arent acustomed to wings/your bigger build they break/fall off (DM's choice).

When you transform your body sparks with necrotic energy dealing 1d6 to all creatures within 5ft.
At levels 5, 11, 15 and 18 you roll an aditionall 1d6 damage.

You have +2 to DEX and STR, and +1d6 max HP per character level for the duration of the transformation. As you look as terrifying as the devil himself you have -4 CHA and disadvantage on all CHA checks, except intimidation which you have advantage in.

Your AC becomes 16, increased with +1 at levels 5, 10 and 15.

You are imune to necrotic damage.

Your Claws and Fangs deal an aditional +1 damage on all attacks.
At levels 5, 10, 15 and 20 this increases with +1 damage.

After (1+character level) hours the transformation wears off if not supplemented with blood (One liter of blood extends the duration with (1+character level) hours). You can not end the duration earlier.

Roll a WIS save (14) when the duration of the spell is over.
If you fail the save you gain two exhaustion points that lasts until you consume 4 liters of blood from a creature with INT above 4. You also have -5 to all STR, DEX and CHA based throws/skills/actions for 48 hours or until the next time you use the spell.
