Blood Let

Choose a target creature you can see within range. The creature makes a Constitution saving throw. On a failure the target is subject to the effects of the spell, on a success, the spell ends for that creature.

While under the effects of this spell a creature cannot benefit from any resistance to Piercing or Slashing damage. When a creature is hit by an attack that deals Piercing or Slashing damage, the creature takes an extra 1d4 of that damage. At the end of each of the target's turns, it may repeat the save, ending the effect on a success.

This spell has no effect on constructs, undead, or elementals.
