As One
Description from the Dor Un Avathar
Allows the Mount ability to effect a player at a range of 5 feet instead of touch. The player who is riding the creature must denote this by stating “riding” every 2 seconds if not touching the mount. If the rider goes more than 5 feet from the steed, he must remount normally. This ability also allows the rider to use both hands freely.
