Horse Growth and Customization

Your horse earns EXP alongside you, as long as you took it out of the stables and set it as your active horse. Your horse’s level can be seen middle-left side of the screen, beside your pet icons. You can also see your horse’s level progress from the Stables. The max level is 10 and you need a maxed out horse to be able to breed it

There are limited options in customizing your horse’s appearance. First, it can equip a Barding or horse armor. You’ll get a free Krenvatz Barding as a sign in bonus (not sure if the offer still stands as of this writing). This doesn’t only give your horse a really cool armor, it also increases the horse’s inventory LT by 500. Otherwise, you’ll have to buy them from the Pearl Shop.

You can change your Horse’s name for free once. You can also change your horse’s appearance by using a Pearl Shop premium item called the Horse Appearance Ticket. You can only select one of the six available designs for that horse.
