[Help] Two Questions, Militia armor update and Resource Creation through spell.
Alright I know this was discussed a while ago but I didn't notice if we ever got an answer as to how to upgrade the city militia's armors by placing an improvement. I just want to upgrade from nothing ==> Gambeson (in my mod also called padded armor) ==> Leather ==> Chain and only make it available at fortresses. I was thinking link it to the blacksmith but then I would have to create an additional tier of blacksmith, beyond what I already have done, so I decided to make an independent city building called a City Armory where when built at the city it upgrades the base armor of the militia and then attach it to the appropriate armor tech +1 so at leather you can produce a armory that provides Gambeson's to your militia and at chain you can add leathers and at plate you can add chain to your militia. Anyways that's the first question.
Second question, I made the world resource necessary for my mod, but I want to make a spell that converts crystal into another resource and steel and crystal into yet another resource. The spell would also cost mana to cast to power the conversion. How do I go about making the two different spells work for requiring a resource to cast and create a new resource?
