Blood Bolt

Blood bolt (cantrip) You hurl a hardened shard of blood at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 piercing. This spell’s damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10). When inflicted with piercing or slashing damage, you activate blood bolt as a reaction and can choose to attack a creature or not.
