Eldritch Volly

1d6 glowing dots appear in the air behind you and launch a volley of eldritch blasts. each blast has the same damage and effects as an eldritch blast. the enemy that is aimed at must made a dex save. if the dex save is failed they will be hit by all of the blasts, if the roll is succeeded they get hit by half of the blasts

the amount of dots increase at higher levels. 2d6 at 10th level 3d6 at 14th level and 4d6 at 17th level
