Cinder Shot

You build smoke and ember in your hand and release it upon your foes. Make a spell attack roll against a creature, on a hit dealing 1d12 fire damage. If you roll a 12 on the damage die, the target is blinded until the start of your next turn.

At higher levels For each spell level higher than 1st used, you fire an extra shot, either at the same target or a new one within range, making a new spell attack for it.
