We were still learning that on the road, actually. The book didn't go much into adding other ingredients- it was kinda something we started messing with at havens. I don't remember exactly how it started. Specs was cooking, and some kind of monster parts got into a flask... it ended up a hell of an explosion when we threw it.

[He uncaps the potion and pours it into the flask. The liquid pools in the base, glowing brightly as it falls and lighting the orb from within, where it begins to pulls gently, absorbing the curative magic much like the potion does when its contents are transformed into a curative.]

I was never that big on chemistry, but every time we played with elemancy at camp we all kinda became scientists, arguing over what to try putting in it next.
