Deathly Touch

You imbue your hand with a sickly energy to harm the next creature you touch. You touch a creature, that creature must make a Constitution saving throw: on a failed throw they take 2d8 necrotic damage, and on a successful throw they take half as much damage.

At Higher Levels. Each level higher than 1st level used in casting, add an extra 1d8 necrotic damage.
