Blinding Strike

The next time you hit a creature with a melee weapon attack during this spell’s duration, your weapon flares with a blinding light of the casters choice, and the target must succeed on a Constitution saving throw vs the casters spell save DC or be blinded until the spell ends.

A creature blinded by this spell makes another Constitution saving throw at the end of each of its turns. On a successful save, it is no longer blinded.

When cast at a higher spell level, add 1 to the difficulty of the constitution saving throw. For example, cast at 4th level Blinding Strike has a DC of the casters spell save modifier + 2
