you can only have 1 of them out, if you have the arctic fox, you can't take out the black leopard.
And? It's literately writen in the tooltip...
that's because the GM read my thread on Reddit and added it afterwards

Hello, PootyPoot ^^
We have updated the in-game text of the Black Leopard package to clarify that those two pet's Talent do not stack.
Thank you for letting us know!
Good luck in your adventures! (。◕‿‿◕。)
Kind regards.
