Amarantha

Aura of Overwhelming Splendor. Amarantha radiates dazzling and mollifying magic. Each creature of Amarantha's choice that starts its turn within 5 feet of her must succeed on a DC 19 Wisdom saving throw or have the charmed condition until the start of its next turn. While charmed, the creature also has the incapacitated condition.

Cauldron Resurrection (Mythic Trait; Recharges after a Short or Long rest). When Amarantha is reduced to 0 hit points, she doesn't die or fall unconscious. Instead, she is bathed in the darkness and transforms. She regains 100 hit points and place a curse on any creature she sees. Any creature within 60 ft. of her must make a DC 16 Wisdom saving throw. On a failed save each creature becomes frightened for 1d4 rounds and takes 22 (5d8) psychic damage or half on a success.

Legendary Resistance (3/Day). If Amarantha fails a saving throw, she can choose to succeed instead.

Magic Resistance. Amarantha has advantage on saving throws against spells and other magical effects.

Multiattack. Amarantha makes two Fae Blade attacks. She can replace one of these attacks with Stunning Soliloquy if available.

Fae Blade. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 20 (3d8 + 7) force damage.

Stunning Soliloquy (Recharge 5–6). Amarantha unleashes a string of magical words. Each creature of Amaratnha's choice within 30 feet of herself must succeed on a DC 19 Wisdom saving throw or have the stunned condition for 1 minute. A stunned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Ridicule. When a creature misses Amarantha with an attack roll, she magically mocks the creature, dealing 5 (2d4) psychic damage to the attacker.

Amarantha can take 3 mythic actions, choosing from the options below. Only one mythic action option can be used at a time and only at the end of another creature’s turn. Amarantha regains spent mythic actions at the start of her turn.
