An interesting concept!
I was liking the idea of it. Combat was a little bland because of lack of abilities.
I wasn't able to finish it because your Adventuring Wizards are WAYYY too powerful. When I fought the one in the shop, she murdered one of my allies with a water spell. With some paralysis and fighting, I finally got her down. I was like, a little harsh, but okay... and then they were in my random encounters.
Then a male wizard casts Blizzard, killing one of my allies, and nearly killing 2 others.
