Blood Fiend

You utter a dark incantation as you cut yourself, letting blood flow from the wound you take 1d6 slashing damage that cannot be prevented by any immunities or resistances. Your entire body and the items you carry becomes sheathed in a layer of blood taking shape like a devil. You gain the following benefits until the spell ends:

• You are immune to poison and necrotic damage.
• You are resistant to fire damage.
• You are vulnerable to radiant damage.
• You are immune to the poisoned condition.
• Your blood forms wings on your back, giving you a flying speed of 40 feet.
• You have a +2 bonus to AC
• All your weapon attacks are magical, and when you make a weapon attack, you can use your spell casting ability modifier instead of Strength or Dexterity for the attack and damage rolls.
• You can attack twice, instead of once, when you take the Attack action on your turn. You ignore this benefit if you already have a feature, like Extra Attack, that lets you attack more than once when you take the Attack action on your turn.
• You have advantage when making Charisma (Intimidation) checks.

When the spell ends the blood becomes inanimate and falls to the ground, covering you. The blood from the wound you created during the casting of this spell has coagulated and causes no further bleeding.
