Trampling Charge. If the triceratops moves at least 20 feet straight toward a creature and then hits it with a gore attack on the same turn, that target must succeed on a DC 13 Strength saving throw or be knocked prone. If the target is prone, the triceratops can make one stomp attack against it as a bonus action.
Gore. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit:24 (4d8 + 6) piercing damage.
Stomp. Melee Weapon Attack: +9 to hit, reach 5 ft., one prone creature. Hit:22 (3d10 + 6) bludgeoning damage.
One of the most aggressive of the herbivorous dinosaurs, a triceratops has a skull that flares out to form a protective plate of bone. With its great horns and formidable speed, a triceratops gores and tramples would-be predators to death.
