Saddleback [Regional]
You can take 10 on Ride checks, even if you are rushed or threatened.
If either you or your mount fails a Reflex save while mounted, you can attempt a Ride check to succeed on the saving throw anyway. The save is successful if your Ride check result is equal to or greater than the spell's Ssave DC. (Essentially, you can substitute your Ride check result for your Reflex save if the former is higher.) You can attempt this substitution once per round for either yourself or your mount. If both you and your mount fail a Reflex save against the same effect, your Ride check result applies to both your save and your mount's save.
