Amulet of the Lion Companion

While wearing this amulet, you can speak its command word as a bonus action to summon a large lion with the statistics of a Guardian Wolf. The Guardian Wolf appears in an unoccupied space you choose within 15 feet of you. It remains as long as you concentrate (as if concentrating on a spell), to a maximum of 1 hour, or until it drops to 0 hit points. It then returns to its home plane.

While summoned, the Guardian Wolf is friendly to you and your companions. It obeys any commands you give it, no matter what language you use. If you fail to command it, the Guardian Wolf defends itself against attackers but takes no other actions.

After the Guardian Wolf departs, it can't be summoned again until the end of your next short rest.
