What I'm trying to do is have a recipe with an item and materials based on the main item's NBT, that results in the original item with additional/changed NBT.   For example, if Weapon(NO NBT) is in a recipe with MaterialOne, I want to add element tag Fire resulting in Weapon(Fire), or if Weapon(Fire) is in a recipe with MaterialTwo I want to remove the tag Fire resulting in Weapon(NO NBT). Or, if Weapon(Fire, Level1) is in a recipe with MaterialThree, I want to increase its Level
