Arcane Parasite

You conjure a magical parasite to suck the energy out of a creature you can see within range. The target makes a Dexterity saving throw. On a failed save, the parasite attaches to it.

At the start of each of the target’s turns, while the parasite is attached to it, it takes 1d8 force damage, and you regain hit points equal to the damage dealt.

A creature can use its action to try and remove the parasite, making a Strength check against your spell save DC. On a success, the spell ends.
