Legendary Resistance (1/Day). If the dragonborn fails a saving throw, it can choose to succeed instead.
Multiattack. The dragonborn makes two Greataxe attacks.
Greataxe. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 11 (1d12 + 5) slashing damage plus 13 (3d8) necrotic damage.
Necrotic Breath (Recharge 5–6). The dragonborn exhales shadowy fire in a 30-foot cone. Each creature in that area must make a DC 15 Wisdom saving throw. On a failed save, the creature takes 36 (8d8) necrotic damage and is frightened of the dragonborn for 1 minute. On a successful save, the creature takes half as much damage and isn't frightened. A frightened creature can repeat the saving throw at end of each of its turns, ending the effect on itself on a success.
