Homebrew
Creature Type. You have two creature types: Monstrosity and Humanoid. You can be affected by a game effect if it works on either of your creature types.
Large Build. Your Strength and Constitution scores can each be increased to a maximum of 22 without assistance from magic items. Being Large also comes with some inherent advantages and disadvantages, which will become clear in play.
Small Arms. For the sake of handling oversized weapons, you are considered Medium.
Equine Hardiness. You have advantage on saving throws that you make to resist the effects of a Forced March.
Wilderness Nomad. You have proficiency in two of the following skills of your choice: Animal Handling, Nature, Medicine, Perception, or Survival
Charge. If you move at least 30 feet straight toward a target and then hit it with a melee weapon attack on the same turn, you can immediately follow that attack with a bonus action, making one attack against the target with your hooves.
Hooves. You have hooves that you can use to make unarmed strikes. When you hit with them, the strike deals 1d6 + your Strength modifier bludgeoning damage, instead of the bludgeoning damage normal for an unarmed strike.
