Ayce, Dragonrider

 Draconic Mount. Ayce is never found without his dragon companion. As a bonus action, he can mount or dismount his dragon companion. When mounted, he has speed 60ft and fly 30ft.

Draconic Ancestry. Ayce, dragonborn-raised-amongst dragons, knows how to tap into the inner power of dragons. As a result, his draconic companion can expel its breath weapon twice per long rest.

Multiattack. Ayce makes one attack with his Morningstar. His dragon companion either expels its breath weapon, makes a bite attack, or makes two claw attacks.

Morningstar. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 8 (1d8+3) bludgeoning damage.

Bite. Melee Weapon Attack: +3 to hit, reach 10 ft., one target. Hit: 15 (1d10 + 3) piercing damage.

Claw. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 6 (2d4) slashing damage.

Poison Breath. The dragon exhales fire in a 20-foot line that is 5 feet wide. Each creature in that line must make a DC 12 Dexterity saving throw, taking 20 (8d4) poison damage on a failed save, or half as much damage on a successful one.
