The thing is I unlocked these years ago back in the TQIT days so no idea why they suddenly dropped in game recently. I haven't played my Conjurer who has these items for a few months since I've been concentrating on the GD expansion playtesting, but as far as I know once those sets are unlocked and drop that's it. They shouldn't drop again. So why have they? And why can't you sell them? My Conjurer is level 28 btw, so no beginner toon. Items were picked up somewhere in Act 3.
I'm wondering if something changed in v1.45 which makes them now drop as other items do. If I'd used the codes the whole set would drop, not just one item from each one. It's weird.
botebote77, as efko says these sets are unlocked by special codes and have always been yellow. If you are playing a toon then if you hit the Escape button it'll call up the following:
Resume Game
Save Game
Options
Unlock Content
Exit to Man Menu
If you hit the Unlock Content and enter one of the codes all parts of that set will drop.
These are the codes:
274267 Shinobi Shozoku
925678 Garb of the Great Merchant
437626 Garb of Germania
373624 Garb of Gaul
6788 Li'l Lued
Assuming Nordic haven't changed them of course.
