Architect Muki

Unholy Devotion. Architect Muki is immune to the effects of any Charisma (deception), Charisma (intimidation), or Charisma (persuasion) check, or any abilities that use such. Additionally, she has advantage on saving throws against being charmed or frightened.

Power Balance. While above 60 hit points, ranged attack rolls against Architect Muki are made at disadvantage. While at 60 hit points or less, Swords of Brexthas, Soulforge Pierce, and Revenant Cannon ignore resistance, and treat immunity as resistance. 

Legendary Resistance (3/Day). If Architect Muki fails a saving throw, s he can choose to succeed instead.

Swords of Brexthas (Thrice per day). Architect Muki invokes the power of the Reikalia. For two hours, or until she dismisses them, five magical swords made of conjured Brexthatine float behind her. The swords are indestructible, and are not affected by difficult terrain. As an action, she can command any number of her swords individually to move up to 60 ft. (fly), and then make a melee weapon attack (+7 to hit, reach 5 ft., 1 target. Hit: 11 (2d10) slashing damage.) The swords can move through creatures space, however only if they have made a melee attack against that creature this turn. If the sword moved at least 30 ft. in a straight line before making this attack, the attack gains a +3 to hit, and deals an additional 5 (1d10) damage, and the entire attacks damage becomes piercing.

Soulforge Pierce (Recharge 5-6). While Swords of Brexthas is active, Architect Muki recalls all her swords to her, where they spin rapidly behind her back, before launching themselves in unison at her foes. The swords move 120 ft. in a straight line, moving through any creatures in their path. Each creature along this line must make a DC 18 dexterity saving throw. On a failed save, a creature takes 28 (8d6) force damage and and 28 (8d6) piercing, or half as much on a success.

Revenant Cannon (Once per day, shares recharge status with Soulforge Pierce). While Swords of Brexthas is active, Architect Muki recalls all her swords to her, where they spin rapidly in a large circle above her, storing up negative energy. Until the end of her next turn, her speed is reduced to 0 and she cannot use her bonus action or reaction. Also until the start of her next turn, all attack rolls against her are made at disadvantage, and the ground within 10 feet of her is difficult terrain. Immediately at the start of her next turn, the energy is released in a massive beam of necrotic energy. Each creature in a 200 ft. long and 15 ft. wide line must make a DC 20 Dexterity saving throw. On a failed save, a creature takes 110 (20d10) force damage, or half as much on a success.

Scatter. When Architect Muki is hit by a melee attack, she can teleport to any unoccupied space she can see within 30 ft. of her.

Architect Muki 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. Vox regains spent legendary actions at the start of its turn.

Afterimage. Hazy afterimages float around Architect Muki, concealing her true position. All attack rolls against her are made at disadvantage until the end of the current creatures turn.

Repel. Architect Muki releases pent up negative energy from within her own soul. Each creature within 15 feet of Muki must make a DC 18 Strength saving throw. On a failed save, they are pushed 10 feet away from Architect Muki and knocked prone.

Razorsphere (Costs 3 Actions). Architect Muki calls her swords to her to defend herself from attackers. Each creature within a 10 ft. radius of Architect Muki must make a DC 18 Dexterity saving throw. On a failed save, they. take 15 (3d10) slashing damage, or half as much on a success.
