Astoria, Knight of Carlello

Legendary Resistance (1/Day). If the dragonborn fails a saving throw, it can choose to succeed instead.

Magma Infusion. As a bonus action the dragonborn can heal 10 hp as long as she has 1 hp per turn

Multiattack. The dragonborn makes three Longsword attacks.

Longsword. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 5) slashing damage, or 9 (1d10 + 5) slashing damage if used with two hands, plus 13 (3d8) fire damage. The dragonborn can cause the sword to flare with bright light, and the target must succeed on a DC 14 Constitution saving throw or be blinded until the start of the dragonborn’s next turn. The sword can flare in this way only once per turn.

Healing Touch (1/Day). The dragonborn touches another creature within 5 feet of it. The target magically regains 40 hit points. In addition, all diseases and poisons affecting the target are removed.

Radiant Breath (Recharge 6). The dragonborn exhales fiery radiance in a 30-foot cone. Each creature in that area must make a DC 15 Dexterity saving throw, taking 44 (8d10) radiant damage on a failed save, or half as much damage on a successful one. When the dragonborn uses this action, it can choose up to three creatures in the cone. These creatures take no damage from the radiance and instead regain 22 (4d10) hit points each.

Dashing Thrust. The Dragonborn dashes forward up to their movement speed and follows up with a single attack. This can be done in conjunction with their other attacks.

The Dragonborn Comes with 3 legendary actions per turn

Imitated Dance (2 actions): The Dragonborn imitates her Master's dance, rolling 3d10 Force damage on a failed dex save of 16 for those within 30 ft of her. 

Godly Flurry (3 actions) : this ability can only be used at 50% health or lower. The Dragonborn targets 4 creatures within 30 ft of each other, the first target must be within 10ft, teleporting to each creatures location and attacking twice. Once the last target is attacked she returns within 5 feet of the initial target, and is vulnerable to all damage until the end of the dragons next turn. This can be flavored by overheating of magma through out her armor, causing it to weaken.
