Instead of crafting new equipment. I would like to be able to craft specific properties onto my equipment, preferably requiring some sort of materials that isn't limited to gold, or residium.
For example. Craft cold resistance onto my armor, or Giantsbane onto my longsword. Or ability to craft custom ammunition, poisoned arrows, explosive xbow bolts.
With some kind of limitation, perhaps only one upgrade per piece of equipment.
I think the main thing is that crafting should allow a player to customize, or make specific pieces of equipment that aren't available to purchase, or acquire elsewhere. If its optional and non unique, I'm not typically going to bother with investing time and any feats/character options into it.
