Character Skins and Transmutation.
1) No.
2) See 1
3) Nope, there is no way to go back and forth between transmutable sets. Once you’ve transmuted the karma stats on the racial armor, your karma armor will be gone forever. You could however simply transmute different items onto both your karma and your racial set. For example, take any exotic item you like the stats of and transmute that onto your racial armor, then get another one of the same exotic item and transmute it onto your karma armor.
You’ll then have a karma item and a racial item with the same stats and you can wear whichever one you like at that moment.
Ah I see what you are saying. Thank you very much for the reply. So I’ll just get a karma set and keep those stats as well as a racial set and look on the TP for the stats that I want and transmute that as well.
