Enfeebling Arrow

You brandish the arrow used in this attack, imbuing it with Arcane Energy, creating an Enfeebling Arrow. When a creature is hit by this arrow, they take an extra 3d6 necrotic damage. Along with that, they must succeed on a Constitution saving throw or they deal half damage (rounded down) with weapon attacks until the end of the caster’s next turn.

Additionally, they lose maximum hit points equal to the number of necrotic damage dealt. This effect will go away after a long rest or after an appropriate magical effect is used to end it.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot above 2nd.
