maybe I just glossed over it, but the Alchemical Exalted don't seem to have any inborn defense against the transformitive powers of the Wyld, nor any charms or protocols dealing with such. Am i just skipping over them?
The closest thing to the Wyld that Alchems have encountered would probably be the Poles. and I don't remember them having any real defense against those either.
Once they come across the Wyld and see the effects it has on them, I see no reason why they would not design protective charms to cover this new challenge.
