Haha, hey, Aspasia is there to cockroach her way through fights, it's not cheating to use the tools the game gives you.
I do think Metatron is usually better tho, also very tanky and can heal allies as well, or herself to be even tankier.
Anyways, yeah, I put WAY too much work into those chocies, it's always very gratifying to hear that people liked them! I'm personally such a carebaer that I tested them all for dev purposes but immediately went Shield on my playthrough, I just like being the good guy and making everyone happy. Mara felt like a dark mirror to the MC, both of them doing similar things for the same reasons, she just didn't have the support she needed to stay on the right path and we have an option to finally improve things.
Thanks for the error report, I'll see if I can track it down.
