Nimblefoot Riding

You have mastered the art of riding upon the back or shoulders of an ally. As long as your weight does not encumber the mounted ally, you gain +2 on all attack and spell attack rolls while riding them. The ally you are riding gains a bonus +2 to their Armor Class as long as you stay mounted. However, they LOSE 10 feet of movement speed per round.

Opponents can make a Strength or Dexterity check with Disadvantage to 'unseat' you. You may use the highest of you OR your ally's ability modifiers to make the roll.

Upon taking this feat, you choose to gain +1 to either Strength or Dexterity.
