Except that i have proof from a
senior GM that they are all AVAILABLE and the triggers to obtain them are all tested and function right now.
This is the latest response from Customer Support
Hi there, REDACTED -
Senior Game Master Varidarel here. Thanks for taking the time to hit us up on this one, and I apologize for the confusion.
The previous Game Master you are referring to was mistaken; the Hidden Artifact Appearances are all in the current patch. I know the search for these can definitely be frustrating. Rest assured though, your character isn't "broken" with obtaining the appearance, and its all actually working correctly.
That being said, Game Masters cannot provide any hints, steps, or advice on how to obtain them. I know it adds to the frustration, but details surrounding it are truly "Hidden."
We can confirm that all methods of obtaining the artifacts are functioning properly, and are not bugged - despite many of the community believing so.
Please note - no information on these have really been put out by Blizzard. Many players are working to try and figure out requirements, and while a lot of good work has been done, not all the information is accurate or extra information/steps are being stated that aren't necessarily true. The appearances and methods to obtain are working, though
Good luck on your hunt, my friend!
