Blood Curse

You curse your own blood, causing it to become poisonous to those who attack you. Whenever a creature makes a melee attack against you, they take 2d6 poison damage. Additionally, you can use your action each turn to spew a 15-foot cone of poisonous blood in front of you. Each creature in the cone must make a Constitution saving throw, taking 3d6 poison damage on a failed save, or half as much damage on a successful one.
