Multiattack

The dragonborn makes two scimitar attacks.

Scimitar

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage.

The dragonborn breathes elemental energy in a 15-foot cone. Each creature in that area must make a DC 12 Dexterity saving throw, taking 10 (3d6) damage of the elementalist's elemental focus type on a failed save, or half as much damage on a successful one.
