Amulet of the Steed

This amulet was created by a ranger of old with a strong bond to their animal companion. Once per day, this amulet can be used to cast the spell Find Greater Steed. The telepathic bond shared between the wearer and steed exists as long as the wearer and creature are on the same plane of existence. Additionally, this amulet can be activated using an action to store the creature in a harmless demiplane contained within the amulet. While there, the steed does not require food or water. Using an action to activate the amulet again releases the steed within 10 feet of the wearer.
