The mount vendor in the main towns sells an armor set for your horse. So far there seems to be at least one bug and one issue with this item:
- Bug is that if you purchase it, it doesn’t show up in your listed armor sets for the mount.
- If you purchase it on one character, you can re-purchase it on another, and it still doesn’t show up
- Price for this “invisible” armor for your mount seems to scale based on your character lvl for some reason, so if you want to obtain this “invisible” armor set for the mount, create a brand new toon and purchase it for the cheapest amount.
