Born to the Saddle

You increase your Dexterity score by 1 to a maximum of 20.

Your mastery as a rider is apparent. You have advantage on saving throws made to avoid falling off your mount. If you fall off your mount and descend no more than 10 feet, you can land on your feet if you're not incapacitated. Mounting or dismounting a creature costs you only 5 feet of movement, rather than half your speed.
