Actions

Multiattack. Absolute Radiance makes 3 attacks: one with her Sword Rain and two with her Orb attack.   Sword Rain. Ranged Weapon Attack: +19 to hit 1d20+18 , reach 120 ft. Absolute Radiance creates 5 magical swords. Each sword targets a creature of her choice. A sword deals 61 10d8+15 (10d8 + 16) piercing damage plus 37 (4d12 + 19) radiant damage.   Orb. Ranged Weapon Attack: +19 to hit 1d20+18 , reach 160 ft. Absolute Radiance forms a ball of concentrated light and launches it. Each orb targets one creature of the Radiance's choice within range, and the targeted creature must make a Dexterity saving throw (DC 22), dealing 38 5d10+10 (5d10 +11) radiant damage on a failed save or half as much on a successful one.   Beam. Ranged Weapon Attack: +18 to hit 1d20+18 , reach 300 ft. Absolute Radiance fires a beam of light from her face. The targeted creature must succeed on a Dexterity saving throw (DC 24) or take 77 11d8+18 (11d8 + 19) radiant damage.   Infection.(1/day) Absolute Radiance fires a pulse of light from her body to infect the minds of civil creatures and return them to a primal state. Any creature within 120 ft. that has an alignment must succeed on a Wisdom saving throw (DC 26) or be charmed by the Radiance for 1 hour. The saving throw automatically fails if the creature is undead, has an Intelligence score of less than 2, or if the creature has any chaotic alignment. Any creature charmed by the Radiance has its Intelligence score changed to 2 for the duration, and may only use their action to do what the Radiance commands on the creature's turn, with the command made telepathically without using an action. The creature may repeat the saving throw whenever it takes damage, ending the effect on a successful save. The effect ends early if Absolute Radiance dies, or if the creature takes any damage from the Radiance.
