Weredraconian

Regeneration. The Weredraconian regains 5 hit points at the start of its turn. If the Weredraconian takes damage from a radiant damage weapon or a spell, this trait doesn’t function at the start of the Weredraconian's next turn. The Weredraconian dies only if it starts its turn with 0 hit points and doesn’t regenerate.

Savagery. At the start of each turn if the Weredraconian has less than 80 hit points, the Weredraconian must make Wisdom saving throw DC 14; on a success, the Weredraconian is in full control of its actions for that turn. On a failure, the Weredraconian moves and makes its Multiattack action at the nearest creature for that turn.

Multiattack. The Weredraconian makes two weapon attacks (from the human form's available melee/ranged weapons) and one bite attack.

Bite. Melee Weapon Attack: +X to hit, reach 5 ft., one target. Hit: 3d4 piercing and 1d6 lightning damage. If the target is a humanoid, it must succeed on a DC 12 Constitution saving throw or be cursed with Weredraconian lycanthropy.

Weapons (melee or ranged). Melee/Range Weapon Attack: +X to hit, distance "X ft.", one target. Hit: "X damage" plus 1d6 lightning damage.

"+X" equals the ranged or melee bonus from the Weredraconian's human stats with proficiency bonus. 

Distance "X ft." equals the reach or range stats for the Weredraconian's human melee/ranged weapons.

"X damage" equal the damage stats for the Weredraconian's human melee/ranged weapons.

Lightning Breath (Recharge 5–6). The Weredraconian exhales lightning in an 30-foot line that is 5 feet wide. Each creature in that line must make a DC 16 Dexterity saving throw, taking 3d12 lightning damage on a failed save, or half as much damage on a successful one.
