War Triceratops

Howdah. The triceratops carries a compact fort on its back. Up to four Medium creatures can ride in the fort without squeezing. To make a melee attack against a target within 5 feet of the triceratops, they must use spears or weapons with reach. Creatures in the fort have three-quarters cover against attacks and effects from outside it. If the triceratops dies, creatures in the fort are placed in unoccupied spaces within 5 feet of the triceratops.

Ballista. The howdah is equipped with a ballista, a massive crossbow that fires heavy bolts. Before it can be fired, it must be loaded and aimed by the howdah’s riders. It takes one action to load the weapon, one action to aim it, and one action to fire it.

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.

Siege Monster. The triceratops deals double damage to objects and structures.
