I activated all the artifacts on my hunter and didn't get the achievement. I bought them on different characters each week and just moved around on all characters to activate them. I'm making this post to help clear things up for me and help anyone getting this achievement in the future. 1. Did I need to buy and activate them on one character? 2. Does moving a token over from another character work? 3. Can I still buy them and unlock the achievement even after I activated them all on all characters? 4. Do I make a new character to fix my problem with them all activated? If you have any solutions or feel like these options answer the problem please let me know.
