Bloodbound Arrow

You infuse an arrow with your blood magic, transforming it into a potent missile of crimson energy. Make a ranged spell attack against a creature you can see within range. On a hit, the arrow deals damage as if it were a regular arrow from your longbow, and the target takes an additional 2d6 necrotic damage.

If the target is a creature of the undead type or has the Fiend or Undead creature tag, the additional necrotic damage is increased to 3d6.

Additionally, on a successful hit, the blood magic binds the target's essence. Until the end of your next turn, you have advantage on Wisdom (Perception) checks to detect the target, and the target cannot benefit from invisibility or become hidden from you.
