The 5th Element allows you to personalize your horse. Thanks to this item, your horse will benefit from an "element" coat randomly selected from amongst the following: Air, Water, Fire, Earth and Metal. These coats come with added bonuses on your horse's skills. Only horses of 1 year 6 months can benefit from this item. The "element" coats are not passed on to the foals. If a horse owns a Golden Apple when you equip a 5th Element, the Golden Apple and its bonuses will be lost.
