If you mean the protection spell that one does not count. That's part of the tutorial. If you lose to the bosses AFTER that they trigger the transformations. I was planning on addressing that in an update.
no I died on purpose to a random enemy after finishing the tutorial because an NPC mentioned "try not to lose so the transformation doesn't trigger!", and then it booted me to the main menu with no load game option
That's just how RPGMaker does Game Overs if it isn't a set encounter with a set lose condition. I'll make it more clear in a future update it's just for bosses!
