This seems really interesting, and makes a lot of sense. But also makes me have balance concern questions.

What's the likelihood this will make some more common ingredients, like plump helmets and pigtails, no longer be good options long term, due to negative syndromes? That's something I would personally like to avoid. I love the idea of different materials having different/realistic reactions and uses.. but I also feel it could be a slippery slope, if any early game materials are nerfed.

Interesting.. should keep on eye with this
