Culling Sickle
The Crooked Moon
You create a ghostly sickle that lasts for the duration and can strike out at your foes. The sickle appears hovering in your space and moves with you, and you can immediately direct it to fly at and strike a creature within 30 feet of you. Make a ranged spell attack. On a hit, the target takes 2d8 Necrotic damage and you gain Temporary Hit Points equal to half the damage dealt. After the sickle hits or misses, it returns to hover in your space.
As a Bonus Action on your later turns, you can repeat the attack against the same target or a different one.
The damage increases by 1d8 for each spell slot level above 3.
