Brilliance

Brilliant radiance shines from your body, shedding bright light in a 60-foot radius and dim light for an additional 60 feet. Until the spell ends, you gain the following benefits:

• You are immune to radiant damage and have resistance to necrotic damage.
• Ability checks and attack rolls based on sight made against you within 60 feet of you have disadvantage. If you are subject to a sight-based effect originating within 60 feet of you that forces you to make a Dexterity saving throw, such as the area of effect of a fireball spell, you have advantage on the saving throw.
• You can use your action to briefly intensify the radiance coming from you. Each creature of your choice within 60 feet of you gains 5d6 hit points and deals 1d10 additional radiance damage on the next attack it makes. This has no effect on undead or constructs. Hostile creatures within 60 feet of you must make a Constitution saving throw. On a failed save, a creature is blinded until your next turn. Once healed or blinded by this action, a creature cannot be affected by it again for the duration.
