As two actions, divine light washes out from you and coalesces in a soft radiance in a sphere that is twice as big as normal around you. Creatures of your choice in that radius when you cast this spell shed dim light in a 1-meter radius and have advantage on all saving throws, and other creatures have disadvantage on attacks made against them until the spell ends. In addition, when a fiend or undead hits an affected creature with a melee attack, the aura flashes with brilliant light. The attacker must succeed on a Fortitude saving throw or be blinded until the spell ends.
