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.

…and expensive enough that you need to be a nobleman or a legendary hero to get it. The cost of the most basic healing potion is enough for a family to eat for a year.
