Blue Ascendant Dragonborn

Legendary Resistance (4/Day). If the dragonborn fails a saving throw, it can choose to succeed instead.

Multiattack. The dragonborn makes three Greataxe attacks. It can replace one attack with either a Shocking Rend attack or a use of Spellcasting to cast Shatter (level 3 version).

Greataxe. Melee Attack Roll: +18, reach 10 ft. Hit: 24 (2d12 + 11) Slashing damage plus 9 (2d8) Lightning damage.

Shocking Rend. Melee Attack Roll: +14, reach 10 ft. Hit: 29 (4d10 + 7) Lightning damage. If the target is a creature, it must succeed on a DC 22 Constitution saving throw or become Stunned until the end of its next turn, at which point it attempts the saving throw again. Success: The condition ends on the creature. Failure: The creature becomes Paralyzed until the end of its next turn, at which point the condition ends.

Lightning Breath (Recharge 5–6). Dexterity Saving Throw: DC 23, each creature in a 120-foot-long, 10-foot-wide Line. Failure: 71 (13d10) Lightning damage. Success: Half damage.

Spellcasting. The dragonborn casts one of the following spells, requiring no Material components and using Charisma as the spellcasting ability (spell save DC 22):

At Will: Detect Magic, Invisibility, Shatter (level 3 version)
3/Day Each: Lightning Bolt (level 5 version), Destructive Wave, Chain Lightning

Beat Wings. Strength Saving Throw: DC 24, each creature in a 15-foot emanation. Failure: 9 (2d8) Lightning damage and pushed 15 feet directly away from the dragonborn. Success: Half damage only.

Tail Attack. Melee Attack Roll: +16, reach 10 ft. Hit: 20 (2d10 + 9) Bludgeoning damage, and the creature is Grappled (Escape DC 24). While a creature is Grappled in this way, it is also Restrained and this attack automatically succeeds against it.

Legendary Action Uses: 3. Immediately after another creature’s turn, the dragonborn can expend a use to take one of the following actions. The dragonborn regains all expended uses at the start of each of its turns.

Cloaked Flight. The dragonborn uses Spellcasting to cast Invisibility on itself, and it can fly up to half its Fly Speed. The dragonborn can’t take this action again until the start of its next turn.

Sonic Boom. The dragonborn uses Spellcasting to cast Shatter (level 3 version). The dragonborn can’t take this action again until the start of its next turn.

Swipe. The dragonborn makes one Greataxe or Shocking Rend attack.
