This spell allows you to conjure a fiendish mount. The the mount takes the form of a Nightmare with the stats of a Warhorse.
Your steed serves you as a mount, both in combat and out, and you have an instinctive bond with it that allows you to fight as a seamless unit. While mounted on your steed, you can make any spell you cast that targets only you also target your steed.
When the steed drops to 0 hit points, it disappears, leaving behind no physical form. You can also dismiss your steed at any time as an action, causing it to disappear. In either case, casting this spell again summons the same steed, restored to its hit point maximum.
While your steed is within 1 mile of you, you can communicate with each other telepathically.
You can't have more than one steed bonded by this spell at a time. As an action, you can release the steed from its bond at any time, causing it to disappear.
