Q:
Can't use the same ascended Accessories?
A:
You can’t use two of an item that are labeled Unique. Contact support and they can get it sorted out.
I did that a couple months ago as well, they gave me an accessory of equal value.
thank you both! I’ve just contacted them
I’d hate to think I just wasted 12 commendations, which aren’t easy to get imo just to find out after the fact I cannot quip it.
