Unholy Aura

Unholy light washes out from you and coalesces in a sickly glow in a 30-foot radius around you. Enemies of your choice in that radius when you cast this spell glow in a dim putrid light in a 5-foot radius and have disadvantage on all saving throws, and other creatures have advantage on attack rolls against them until the spell ends. In addition, when an affected creature is struck with a melee attack, the aura surges with sickly green light. The victim must succeed on a Constitution saving throw or be blinded until the spell ends.
