Wild Phantom Blade

You create a floating, spectral blade made of energy from the feywilds that floats within your space that lasts for the duration or until you cast this spell again. When you cast the spell, you can make a melee spell attack against a single creature within 60 feet of yourself when ever you hit it with an attack roll once per turn. On a hit, the target takes force damage equal to 3d4 + your spellcasting ability modifier in force damage.

At Higher Levels. When you cast this spell using a spell slot of 4rd level or higher, the damage increases by 1d4 for every slot levels above 4th.
