Trampling FeeThis is:

Let’s say that this triceratops moves 20ft. straight towards the creature, and hits it with a gore strike on the same turn. The target should succeed on a DC13 strength saving throw or be knocked out. The Triceratops can make a Stomp attack against a target if it is prone. This is a Bonus Action.

Actions

Gore: Melee Weapon Attack – +9 to hit. Reach 5ft., one target. Hit: 24 (4d8+6) Piercing Damage

Stomp: Melee weapon attack: +9 to hit. Can reach 5ft., one prone creature. Hit: 22 (3d10 + 6), bludgeoning damage
