Swirling Vortex of Cano

The user generates the power of the stars into the palm of their hand. After generating the energy they then launch an attack with the constant swirling vortex of starry energy to their opponent. On a hit, the target takes 4d8 radiant damage. On hit, the user must make a Constitution saving throw. If it fails, the target is blinded for the duration of 1 minute. At the end of each of its turns, the target can make a Constitution saving throw. On a success, the user is not blinded.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the initial radiant damage increases by 1d8 for each slot level about 6th level.
