Traits

Charge. If the hart moves at least 20 feet straight toward a target and then hits it with an antlers attack on the same turn, the target takes an extra 7 (2d6) fire damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be knocked prone.

Heated Body. A creature that touches the hart or hits it with a melee attack while within 5 feet of it takes 5 (1d10) fire damage.

Sure-Footed. The hart has advantage on Strength and Dexterity saving throws made against effects that would knock it prone.

Antlers. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit:7 (1d8 + 3) piercing damage.

Hooves. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit:5 (1d4 + 3) bludgeoning damage plus 2 (1d4) fire damage.

Lore

Among the first anvilwroughts to be forged by Purphoros, elegant burnished harts wander the mortal realm in search of new sights to bring back to the god of the forge. On every trip from Mount Velus, where Purphoros has his forge, they seek out the far reaches of the world so they can witness beauty in all its forms, then later reunite with their creator, their minds filled with tales of how life's splendor continues to develop.
