My problem with this is that your example replies on you already knowing the correct answer, so that you know it’s given you the wrong answer and you can go back and try to trick it into giving a different answer. If you’re asking it a question to which you don’t already know the answer, how would you know if this has happened?
Yeah. Your main combat level is on the player/companion, so it’s much easier to change up your team and try out different beasts. Individual beasts do have levels, but that’s more about when you can ‘remaster’ (i.e. evolve) them and to unlock moves (which you can swap out at will). Also, elemental type effects are so much more interesting than just a flat damage bonus, and the music is really good. So in summary, yes, I would highly recommend.
