The myth says for any head being chopped off, two will grow back, but if we could put a limit on how many heads she can grow overall at the moment (say, for instance, four) that would be great. It would be up to you of course if a head was to be chopped off. It is just to make sure that you don't end up with an overpowered character (in terms of having a hundred heads suddenly).

Could I possibly ask you to put into your profile that the NPCs cannot be used in battle threads, but can be used in quest ones as companion fighters?

Thank you
