Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) slashing damage.
Tail Slap. Melee Weapon Attack: +7 to hit, reach 10 ft., one creature. Hit: 11 (2d6 + 4) bludgeoning damage.
Fire Breath. The proto-dragon exhales fire in a 60-foot line. Each creature in that area must make a DC 15 Dexterity saving throw, taking 42 (12d6) fire damage on a failed save, or half as much damage on a successful one.
Description
More primal offshoots of true dragons, proto-dragons, similar to wyverns, have two scaly legs, leathery wings, and a sinewy tail, though they lack the wyvern's venomous sting. They can exhale mighty blasts of flame from their mouths, and though lacking a true dragon's mighty intellect, are possessed of a savage cunning, and a talent for destruction.
