Darkness Bolt

From your hands a mist of darkness begins to spew from them. You begin concentrating and weaving signs with your hands before clasping them together, condensing the darkness. As you pull your hands apart the darkness forms into 6 spheres. As long as you maintain concentration and you have spheres left to launch, you can as an action, make a ranged spell attack to launch up to 2 spheres at a target one or two targets that you can see within 120ft, dealing 1d10 cold damage. As a bonus action you can launch a 3rd larger sphere as part of the action that explodes in a radius of 20ft dealing 4d6 cold damage. A creature hit by any of these spheres must make a Constitution saving throw or become consumed by the darkness becoming blinded for 2 turns. On a successful save the creature is not blinded.

At higher Levels. Casting this spell at levels 4, 6, 8 increases the damage by 1d10 and 2d6 and the explosion radius by 5ft respectively for every 2 levels casted above the 2nd.
