In a quest, I got equipment for my horse (I think it's the equipment that the princess's horse had, or something like that)
Does this equipment change anything? And if I don't like how it looks, can I remove it or go back to the default equipment in some way?
Best Answer
All of the horse armor in the base game is cosmetic. However, the Champions' Ballad DLC Pack 2 added two pieces of equipment which give your horse new abilities.
You can earn these items by completing the EX Ancient Horse Rumors side quest. Aside from these two items, any other saddles or reins are purely cosmetic.
As Yuuki mentioned, you can change your horse's saddle, reins, or mane style by visiting a stable and talking to the person tending to the horses.
