Brumhilde

Boon of Immortality. Brumhilde is immune to any effect that would age her, and she can’t die from old age.

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

Graystaff Magic. The hag carries a graystaff, a magic staff. The hag can use its flying speed only while astride the staff. If the staff is lost or destroyed, the hag must craft another, which takes a year and a day.

Magic Resistance. Brumhilde has advantage on saving throws against spells and other magical effects. (This trait is bestowed by her robe of the archmagi.)

Special Equipment. Brumhilde wears a robe of the archmagi and carries a graystaff.

Multiattack. Brumhilde makes two Frost Shard or Slam attacks.

Frost Shard. Ranged Spell Attack: +16 to hit, reach 5 ft. or range 120 ft., one target. Hit: 25 (5d6 + 8) cold damage, and if the target is a creature, it must succeed on a DC 22 Constitution saving throw or be stunned by Brumhilde until the start of her next turn.

Horrific Feast. The hag feeds on the corpse of one enemy within reach that died within the past minute. Each creature of the hag’s choice that is within 60 feet and able to see the feeding must succeed on a DC 22 Wisdom saving throw or be frightened of the hag for 1 minute. While frightened in this way, a creature is incapacitated, can’t understand what others say, can’t read, and speaks only in gibberish. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to the hag’s Horrific Feast for the next 24 hours.

Life Sap (Recharge 5–6). Brumhilde draws the the life force of those in a 20-foot-radius sphere towards her. Each creature in that area must make a DC 22 Constitution saving throw, taking 40 (9d8) necrotic damage on a failed save, or half as much damage on a successful one. Brumhilde gathers the energy into a small sphere of shadow and bites into it like an apple, regaining hit points equal to half the damage rolled.

Spellcasting. Brumhilde casts one of the following spells, requiring no material components and using Intelligence as the spellcasting ability (spell save DC 24, +16 to hit with spell attacks):

At will: detect magic, ray of frost, invisibility, hold person, dissonant whispers, fear, Rime's binding ice, flock of familiars

3/day each: dispel magic, cone of cold, ice storm,wall of ice

1/day each: time stop, weird, finger of death, maddening darkness

Fey Step. Brumhilde teleports, along with any equipment she is wearing or carrying, to an unoccupied space she can see within 30 feet of her.

Negate Spell (2/Day). When Brumhilde sees a creature within 60 feet of her casting a spell, she tries to interrupt it. If the creature is casting a spell using a spell slot of 8th level or lower, its spell fails and has no effect. If it is casting a 9th-level spell, it must succeed on a DC 22 Intelligence saving throw, or the spells fails and has no effect.

Shadow Hold. Brumhilde snags the shadow of a creature withing 20 feet of her, holding them in place for one round. This functions like the hold person.

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

Witchcraft. Brumhilde uses Spellcasting or Fey Step.

Dark Speech (Costs 2 Actions). Brumhilde utters a phrase in a forbidden language and targets one or two creatures she can see within 60 feet of her. Each target must succeed on a DC 22 Wisdom saving throw or take 11 (2d10) psychic damage and be frightened of Brumhillde for 1 minute. A target can repeat the save at the end of each of its turns, ending the effect on itself on a success and thereby becoming immune to Brumhilde’s Dark Speech for 24 hours.

Fey Beguilement (Costs 3 Actions). Brumhilde targets one creature she can see within 60 feet of her. The target must succeed on a DC 22 Charisma saving throw or be possessed by a fey spirit. While possessed, the target must obey Brumhilde’s commands. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
