I've been trying to add a few items to the game which hasn't been an issue. those worked and I have them appearing in different qualities the way I want but I cannot figure out how to tie them to a perk. They each require ranks in a perk to unlock but can only ever be crafted in quality 1. I'm not sure what the entry to an item or blocks xml should be to make it governed by a specific perk. Or is it something in the progress xml that says what it specifically effects? thank you in advance for any help.
