Looking to have a config/toggle that allows enchants and other nbt tags (i.e. EnderIO Dark Armor) to be additive. Example: Thaumcraft robe might require reskillable:magic|15 and reskillable:defense|5. If I enchant with with protection IV with a reskillable:magic|4 requirement then the new enchanted robe would now be magic|19 and defense|5. This could also help with Tinker's Tools by making specific upgrades cost a static amount that is added to the base tool to use.

The current system only takes the highest of the two so the enchanted requirement is the same as the unenchanted requirement. There could be a skill max check to cap the total requirement at the max skill but this will make having 3 enchants more difficult to equip than 1 enchant...which makes sense to me.

this request goes nicely with the oreDict ticket....hence all "ore:pickaxe" items with an enchant tag would require compatskill:xxxxxxx|4 (or reskillable:magic|4) additional requirement if you put the fortune IV enchant (nbt tag) on a pickaxe that is added to a oreDict. This systems allows dynamic skill requirements per tool/weapon/armor.
