So anyways after running magic tower i wondered if it could be reset with dungeon reset cards(seeing as how you could get them from the NPC) and long behold it did reset the dungeon.... Well kinda. Even tho the dungeon reset the quest it gives do not. So seeing as it doesn't reset the quest there doesn't seem to be a point in it being able to reset.
Now im not sure if it was meant to be like this or not but without the quest you cant progress at all.
Anyways just thought id mention this just in case its an error of some sort.
