Turning monster girls into magical girls is restricted to plot only, for example you need to wish for it or perform a complex ritual (with the other posters consent).

I know but I'm not talking about that Dark Magical Girl CYOA section. It's mentioned in the primary module as well (There's Purification artifacts for instance) and it's mentioned in the section on light powers as being a kind of halfway point between Fire and Reinforcement, or something like that. Or am I just getting myself confused and it has no benefits aside from plot specific applications?
