DEATH BLADE

You evoke a necrotic blade in your free hand. The blade is similar in size and shape to a scimitar, and it lasts for the duration. If you let go of the blade, it disappears, but you can evoke the blade again as a bonus action. You can use your action to make a melee spell attack with the necrotic blade. On a hit, the target takes 3d6 necrotic damage. The necrotic blade absorbs light in a 10-foot radius creating a sphere of darkness, the casters vision is unaffected.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for every two slot levels above 2nd.
