You've spent endless hours learning how to handle a horse in a fight.
Region: The Horse Plains.
Benefit: If you or your mount fail a Reflex save while mounted, you can attempt a Ride check to succeed on the saving throw. The save is successful if your Ride check result is equal to or greater than the effect's save DC (essentially, your Ride check result becomes your Reflex save if it's higher than the result you achieved with your Reflex save). You can attempt to do this once per round for either yourself or your mount. If both you and your mount fail a Reflex save against the same effect (for example, a fireball spell or a dragon's breath weapon that catches you and your mount in the area of effect), your Ride check result applies to both you and your mount's save.
