Call of Midnight

The Blade of Midnight draws much of its power from the Void, where it was forged.  A sphere of energy forms when Called onto one target creature within range. The target must make a dexterity saving throw. The creature takes 12d10 force damage on a failed save, or half as much damage on a successful one.

Additionally, after the initial attack, all creatures within 60 feet of the spell's initial center point must make a constitution saving throw, as the sphere explodes into blinding light. A target takes 2d10 force damage and becomes blinded until the start of your next turn on a failed save. On a successful save, the creature takes half damage and is not blinded.
