Holy Aura

Holy Aura: (permanent aura) Divine light washes out from you and coalesces in a soft radiance in a 10-foot radius around you. Creatures of your choice in that radius now shed dim light in a 5-foot radius and have advantage on all saving throws, and other creatures have disadvantage on attack rolls against them while you remain conscious. In addition, when a fiend or an undead hits an affected creature with a melee attack, the aura flashes with brilliant light. The attacker must succeed on a Constitution saving throw or be blinded until the end of their next turn.
