That's why I said "not much use" and not "no use".

But requiring magical draining of life force in the creation of a paut like substance sounds in the ballpark.

I'm not sure that an Infusion that replicates paut is really a violation of the "no magic to help magic" rule, since it doesn't create any obvious recursive bonus explosions. If it is possible, then you can certainly combine it with sacrifice.

The other possibility is just have a form of raw magic extractable from living things in the setting.
