Chattering Steed

Select a corpse of a Pegasus, Saber-toothed Tiger, Cave Bear, Giant Constrictor Snake or Giant Spider to cast the spell.  Raise the monster up as your steed.  It has the same statistics in the monster manual though it's creature type is now Undead.

You control the mount in combat. While mounted on it, you can make any spell you cast that targets only you also target the mount.

The mount dies when it drops to 0 hit points. Casting this spell again reanimates the mount, with all its hit points restored and any conditions removed.

You can’t have more than one mount bonded by this spell or ghastly mount at the same time. As an action, you can release a mount from its bond, causing it to die.
