I'm slowly gaining skill in Enchanting, up to 122 now, and I'm wondering. Do we need to keep all the runed rods as we skill up? Or, say, is having a Runed Silver Rod able to replace the need for a Runed Copper Rod?
Unfortunately the answer is; You need each ingrediant listed in the reciepe :( My skill is 259 and i just today put my runed copper rod in the bank in hopes i wont need to drag it around anymore :P But if in fact i want to enchant +1 to all resists on a cloak again i will have to drag the poor thing back out.
Hope this helps, i know its not the answer you wanted :)
