Architect Vox

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

Exoplis. While airborne, as a bonus action or reaction Vox can move horizontally to an unoccupied space within 30 feet of him. Until he successfully lands on a solid surface, his AC increases by two and he cannot use Exoplis again.

Crushing Judgement (recharge 5-6). Vox magically launches himself up to 45 ft. in any direction. He then uses his hammer to send a violent magically charged shockwave through the air. Each creature in a 20 ft. sphere centered on Vox must make a DC 18 dexterity saving throw, taking 35 (10d6) bludgeoning and 35 (10d6) force damage and be knocked prone on a failed save, or half as much damage and avoid being knocked prone on a success.

Devastate (recharge 5-6.) Vox magically launches himself straight down to the nearest surface, absorbing the impact of the fall into his Hammer. He then uses his hammer to send a violent magically charged tremors into the ground. Each creature in a 15 ft radius of Vox  touching the ground must make a DC 16 dexterity saving throw, taking 35 (10d6) bludgeoning and 35 (10d6) force damage, take additional damage equal to how much damage Vox would have taken had he suffered the damage of the fall, and be launched 20 ft straight up in the air, or half as much total damage and not be flung on a success.

Multiattack. Vox makes two Lawmaker attacks, and can then make a use of either Devastate or Crushing Judgement if recharged.

Lawmaker. Melee Weapon Attack: +13 to hit, reach 5 ft., # target. Hit: 14 (2d6 + 7) bludgeoning damage. 

Vox moves horizontally to an unoccupied space within 30 feet of him. Until he successfully lands on a solid surface, his AC increases by two and he cannot use Exoplis again. (See traits)

Exoplis (see traits). Vox moves horizontally to an unoccupied space within 30 feet of him. Until he successfully lands on a solid surface, his AC increases by two and he cannot use Exoplis again.

Vox 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.

Skull Crusher (Costs 2 Actions). Vox magically launches himself up to 45 ft. towards a creature within range. The creature must then make a DC 20 Dexterity saving throw. On a fail, the creature takes 14 (2d6 + 7) bludgeoning damage as the hammer knocks them sideways, and then make a DC 15 Strength saving throw or take an additional 21 bludgeoning damage (4d6 + 7) and be knocked prone.

Reikalia's Glare. The creature who's turn it now is must make a DC 15 Wisdom saving throw. On a fail, they are frightened by Vox until the start of their next turn.
