Jsk Feats:Mounted Combatant

You are a dangerous foe to face while mounted. While you are mounted and aren't incapacitated, you gain the following benefits:
 * You have advantage on melee attack rolls against any unmounted creature that is smaller than your mount.
 * You can force an attack targeted at your mount to target you instead.
 * If your mount is subjected to an effect that allows it to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.
