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 or an improved die (your choice, situationally decided) 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.
