Des's Spite

You channel spiteful arcane anger, pulling life force from a target that you can see within reach and forming it into an unbreakable magical bead. The target takes 14d6 Necrotic damage and must make a CON saving throw. On a failed save, the target's hit point maximum is reduced by this amount permanently. This can only be reversed by the caster recasting the spell to break the bead and release the life force, or a Wish spell.

Any creature whose hit points are reduced to 0 by this spell, and who fail the Constitution saving throw, die instantly, and the bead of life force fades from existence. A creature killed this way cannot be brought back by magical means short of True Resurrection or Wish spell.
