I've noticed that SKSE adds member functions for ConstructableObjects, but I'm not sure how to make use of them. How would I make it so that when a player picks a perk, the recipe result count for Dwarven Armor is doubled? Or the first ingredient is switched or has its requirement reduced?

Actually, nevermind. I'm assuming you'd set them as properties of the script attached to an ability that the perk adds to the player, and then manipulate them from within the script. If that's correct, would it be possible to adjust the result count for every armor with a specific keyword (without having to manually add them all as properties of the script)?
