To unlock this achievement you’ll need to dedicate some time to being a mounted archer, and if this isn’t your thing then you’ll have to learn how to shoot a bow while moving on a mount! You won’t be able to use all bows while mounted by default, but you can unlock this ability by investing in the Horse Master perk, which can be unlocked at skill level 225 with the Bow. You can invest in perks from the Riding perk tree to improve your accuracy with bows while mounted, making it easier to kill enemies using this method.
