Mount. Horses have been trained to act as mounts for creatures smaller than them, a willing horse can be mounted using half your movement speed. The initiative of a horse changes to match yours when you mount it. While mounted, it moves as you direct it, and it has only three action options: Dash, Disengage, and Dodge. A horse can move and act even on the turn that you mount it. If an effect moves your horse against its will while you're on it, you must succeed on a DC 10 Dexterity saving throw or fall off the horse, landing prone in a space within 5 feet of it. If you're knocked prone while mounted, you must make the same saving throw. If your horse is knocked prone, you can use your reaction to dismount it as it falls and land on your feet. Otherwise, you are dismounted and fall prone in a space within 5 feet it.   Charge. If the horse moves 20 feet straight toward a target and then hits it with a ram attack on the same turn, the target takes an extra 2 (1d4) bludgeoning damage. If the target is a creature, it must succeed on a DC 10 Strength saving throw or be knocked prone. If the horse moves 40 feet, the target takes an additional 2 (1d4) bludgeoning damage and the target rolls its saving throw with disadvantage.   Charge (mounted only). If the horse moves 20 feet straight toward a target and the rider hits it with a Lance melee weapon attack on the same turn, the target takes an extra 2 (1d4) bludgeoning damage. If the target is a creature, it must succeed on a DC 10 Strength saving throw or be knocked prone. If the horse moves 40 feet, the target takes an additional 2 (1d4) bludgeoning damage and the target rolls its saving throw with disadvantage.
