You summon a spirit that assumes the form of a loyal mount. The spirit appears in range and takes on a form you choose (ex: griffon, pegasus, dire wolf, rhinoceros, saber-toothed tiger). The creature has the stats provided in the Monster Manual for the chosen form, though it is a celestial, fey, or fiend instead of its normal creature type. Additionally, if it has an Int score of 5 or lower, its Int becomes 6, and it is able to understand 1 language of your choice. While the mount is within 1 mile, you can communicate telepathically. While mounted, any spell you cast that targets only you, also target the mount.
The mount disappears temporarily when it drops to 0 hit points or when you dismiss it as an action. Casting this spell again re-summons the bonded mount, with all its hit points restored and any conditions removed. Whenever the mount disappears, it leaves behind any objects it was wearing or carrying.
