So the problem I see here is that when I check the unique gems allowed, one-time Nightbane quest reward gems are suggested and of course there is no way to get a second one on the way.
This is the quest in mind and 3 gems I’m talking about.
While they are unique, it’s not like you can farm them the way you can get the gems from heroics or the ones you can buy for the honour currency. I guess someone would argue with me these should stay, but it feels they are so unique one-time use, they should be not supported (or if you really want, supported via another checkbox which I personally feel like is unnecessary).
PS. I just went to Kalynna Lathred, just in case there’s something I’m not seeing and no, it’s not repeatable.
