The creature moves up to 30 meters and makes an attack, rolling two d20s and keeping the better result. If the attack succeeds, in addition to normal damage, a victim of equal or smaller size than the creature must make an opposed Strength check or be Knocked Prone. In that case, the creature tramples (or gores) its victim and the damage is doubled.

When it takes a critical hit or its hit points drop below half, the creature becomes enraged. It ignores pain and fear penalties, gains a +5 bonus to its melee attack score, and +1d6 to its damage. It can still act for one full round after reaching 0 hit points.

On a successful charge, if the victim is smaller than the creature, it is also thrown [1d6+1] meters away (more or less depending on the size of those involved). It must succeed on a DC 15 Constitution check or be Stunned. Each round, it may attempt a new Constitution check to regain its senses.
