Bronze Dragonborn Cavalier

Bonded Mount. The dragonborn is magically bound to a wyvern trained to serve as its mount. While mounted on this wyvern, the dragonborn gains the wyvern’s senses. The bonded mount obeys the dragonborn’s commands. If its mount dies, the dragonborn can train a new wyvern to serve as its bonded mount, a process requiring a month.

Firearms Knowledge. The dragonborn’s mastery of its weapons enables it to ignore the loading property of any firearm.

Multiattack. The dragonborn makes two Longsword, Musket, or Pistol attacks.

Longsword. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 4) slashing damage, or 9 (1d10 + 4) slashing damage if used with two hands.

Musket. Ranged Weapon Attack: +4 to hit, range 40/120 ft., one target. Hit: 8 (1d12 + 2) piercing damage.

Pistol. Ranged Weapon Attack: +4 to hit, range 30/90 ft., one target. Hit: 7 (1d10 + 2) piercing damage.

Force Grenade. The dragonborn throws a grenade up to 60 feet, and the grenade explodes in a 20-foot-radius sphere. Each creature in that area must make a DC 15 Dexterity saving throw, taking 17 (5d6) force damage on a failed save, or half as much damage on a successful one. After the dragonborn throws the grenade, roll a d6; on a roll of 4 or lower, the dragonborn has no more grenades to throw.

Lightning Breath (1/Day). The dragonborn exhales lightning in a 30-foot line that is 5 feet wide. Each creature in that line must make a DC 13 Dexterity saving throw, taking 6 (2d6) lightning damage on a failed save, or half as much damage on a successful one.

Feather Fall. The dragonborn wears a magic ring with which it can cast the feather fall spell on itself once as a reaction to falling. After the spell is cast, the ring becomes nonmagical.
