Warghuth the Horn of Sartek

Trampling Charge. If Warghuth moves at least 20 feet straight toward a creature and then hits it with his goring horn attack or cleaving strike on the same turn, that target must succeed on a DC 16 Strength saving throw or be knocked prone. If the target is prone, Warghuth can make one attack with his mount's hooves against it as a bonus action.

Multiattack. Warghuth makes three attacks: one with his mount's goring horn, and two with his cleaving strike. When its petrifying breath is available, it can use the breath in place of its goring horn or cleaving strike.

Goring Horn. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 18 (2d12 + 5) piercing damage.

Hooves. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 16 (2d10 + 5) bludgeoning damage.

Cleaving Strike. Melee Weapon Attack: +12 to hit, reach 5 ft., one target. Hit: 24 (2d12 + 12) slashing damage.

Petrifying Breath (Recharge 5–6). Warghuth's mount exhales petrifying gas in a 30-foot cone. Each creature in that area must succeed on a DC 14 Constitution saving throw. On a failed save, a target begins to turn to stone and is restrained. The restrained target must repeat the saving throw at the end of its next turn. On a success, the effect ends on the target. On a failure, the target is petrified until freed by the greater restoration spell or other magic.
