While mounted are you required to hold the reins in order to direct your mount? If so, with both hands or just one? If not, do you direct the mount with your feet, have you lashed the reins to your arm or maybe do you use verbal commands, etc.? Also, do you include your own weight when figuring out if the mount is encumbered or do you count only your weapon(s)/armour/gear? If you include your own weight in the calculation how would a Dragonborn Paladin ever be able to ride anything? Thank you kindly.
