Darkness blast

Launch a projectile made of absolute darkness at a Target. Make a ranged spell attack. On hit: [roll]2d6[/roll] necrotic damage. Target must roll a constitution saving throw or take 3d10 necrotic damage. They also gain a temporary dark aura on a failed save, which blinds them unless they have superior dark vision, in which case it decreases their vision to 30 feet, or dark vision, in which case their vision is limited to 10 feet. This dark aura is dispelled by any magical light. This includes any form of light created by magic, including fire spells, although fire spells only work if the cursed individual is either damaged by fire or light or casts a spell involving fire or light. If you gain the blinded condition from light or are in the presence of a magical light spell such as faerie fire, the dark aura is dispelled. If you take damage and are cursed by this attack, all other cursed creatures within 100ft of you take half of the damage that you take from the attack.
