Question About Skirmish Stones Needed For Idris

Is it possible to use any of the pouches from the current login campaign (which give +1 stones) to trade them and get the same stone, but NQ?

Stones needed: Ghastly, Verd, Wailing Stone x200

if the page is correct, you can get 160 obsidian fragments per wailing+1, which can then be redeemed for 16 ghastly, 8 verdigris, or 4 nq wailing

you can also redeem copper vouchers for obsidian fragments

You can convert (with loss) skirmish stones to obsidian frags (and vice versa) with ornery dhole.

But you can also convert cooper vouchers for obsidian frags.

Another cheap way to get stones is converting merits for the stones with emporox. It will require first a donation of 12 rakaznar skirmish wings though, but the rate of merit:stones is pretty good imo.
