Blood Weapon

You create a floating, Blood weapon that forms into a weapon of your choice and lasts for the duration. The force appears within range in a space of your choice, and you can immediately make one melee spell attack against one creature within 5 feet. When made from the blood of fallen enemies, roll with advantage. 

On a hit, the target takes Nectoic damage equal to 1d8 plus your spellcasting ability modifier.

As a Bonus Action on your later turns, you can move the force up to 20 feet and repeat the attack against a creature within 5 feet of it.
