Calcifur's Calcium Cutlass

Tossing the components into the air you form them into a cruel razor, pallid and smooth 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 blade. On a hit, the target takes 3d6 necrotic damage. The blade counts as a spell focus for the duration.
