They're brand new forms. I modeled each one after an existing form of the same tier/foci, but all five forms are new and have a unique configuration of stats, skills, etc., and none are carbon copies of another form.

I will confess though that I'm not entirely done with them, so what exactly they'll have and do isn't set is stone yet. They are playable as-is, but the final product will depend a lot on how much time I'm able to spend on them in the coming days.
