Black Bolt

You hurl an inky black blob towards your target. Make a ranged spell attack. The blob flies towards the targets head if it has one, if not it heads for center of mass. On hit, the target takes 3d6 necrotic damage and makes a constitution save against your spell save dc. On a fail, the target is blinded until the blob is removed. The blob may be removed with an action, and any creature may make the action to remove. On a success the target is not blinded.
