Sanguine

Subclass featureValdaSpire242014Witch

When you cast a spell with a spell slot that deals damage to a creature that is the sole target of your Hex, you can choose to sacrifice your blood for power. You take 5 or more Necrotic damage and the target takes an extra 1d8 Necrotic damage for every 5 Necrotic damage you took, to a maximum of 6d8 Necrotic damage. This damage ignores your Resistance and Immunity, and bypasses your Temporary Hit Points.
