Powerful Build
You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.
Tri-Horn
Your horns, which sprout from your nose and brows, are a natural weapon that you can use to make unarmed strikes. If you hit with your horns, you deal piercing damage equal to 1d6 + your Strength modifier, instead of the bludgeoning damage normal for an unarmed strike.
Piercing Charge
If you move at least 20 feet in a straight line, you may make a special attack with your horns. If you hit with it, you deal an additional 1d6 piercing damage to the target.
