Radiant Flames (1/Day)
Multihued flame surrounds the cultist for 1 minute, until the cultist is incapacitated or dies, or until the cultist extinguishes the flame (no action required). While inflamed, the cultist has telepathy with a range of 30 feet, and it can teleport as a bonus action up to 30 feet to an unoccupied space it can see. In addition, every creature that starts its turn within 5 feet of the cultist must make a DC 15 Dexterity saving throw, taking 16 (3d10) radiant damage on a failed save, or half as much damage on a successful one.
