Hi veday42, thank you for trying out Bylina!
Yes, the Prince Charming quest can be inconvenient, but TPK is not that harsh in this game, and I think it creates an even better story if this happens ill-timed.
There is a cure for Wava's spell, though reloading is an easier option I guess. I know of a couple of players who accepted their fate and even completed the game in that form though.
The animal companions might be considered as a challenge, but they can have their advantages as well. Mehera has a huge inventory for example.
There is still something you can do with Milos, but you are right, the quest can be considered finished in that state. I'll update this in the next release.
Thanks for the feedback, and I wish you happy adventuring!
