Amulet of the lost

You summon a [ monster ]panther[ /monster ] Keen Smell. The panther has advantage on Wisdom (Perception) checks that rely on smell. Pounce. If the panther moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 12 Strength saving throw or be knocked prone. If the target is prone, the panther can make one bite attack against it as a bonus action. The beast obeys your commands as best as it can. It takes its turn on your initiative. On your turn, you can verbally command the beast where to move (no action required by you). You can use your action to verbally command it to take the Attack, Dash, Disengage, or Help action. If you don't issue a command, the beast takes the Dodge action. Once you have the Extra Attack feature, you can make one weapon attack yourself when you command the beast to take the Attack action. If you are incapacitated or absent, the beast acts on its own, focusing on protecting you and itself. The beast never requires your command to use its reaction, such as when making an opportunity attack. The beast returns to the amulet in it is killed or if you dismiss it. You can concentrate for 1 minute or burn a spell slot to cast the find familiar spell. If you do you don not need the material components. The beast can only take the form of a panther and can attack. Otherwise it gains all other abilities of the spell.
