Xander created this item after a series of mishaps with steeds running off, being stolen, eaten or otherwise made unalive. Anyone possessing the horseshoe merely need speak the command word equestria (this is cast into the shoe) and it will summon a steed with appropriate equipment (i.e. horse with saddle and bridle, oxen with yoke, etc.). The steed will remain for 24 hours or until dismissed by the user. The lucky aspect of this item is because of the link between rider and the summoned mount, all related animal handling checks are made with advantage.

There are 3 varieties of this item, iron, adamantine, and mithral. The iron variant while most common of the types is a very rare find, as they are one time use. The horseshoe will begin to rust after casting and fully turn to dust after 24 hours. It is also limited to just the most common beasts as steeds; dogs, goats, ponies (for smaller humanoids) mules, draft horses others by DM's discretion. These are NOT war mounts. The steeds will dissipate if they take damage and require a short rest before being re-summoned. 

The adamantine is the same as the iron type in all ways, except it is reusable. These are also extremely rare as they were made in very small numbers only about a dozen exist.

The mithral version was Xander's perfection of the item. All steeds summoned have the stats and damage capabilities of their native equivalent. There is also a 1 in 10 chance to summon an elite mount; warhorse, griffon, wyvern, drake etc. (if player summons 9 draft horses, the tenth will automatically be an elite mount)

Notes: Advantage: Animal Handling, Buff, Movement, Exploration
