This is my first time posting on the forums as I was not too aware of the official forums existing, and whether if I'd ever need it. Still, if this has already been addressed by someone I apologize for the "repost".

On the questline for acquiring your "Blade of Gunnhildr" weapon in Bozja I had decided to get a second one now months after release of Endwalker. With the shift in content and of course into a new expansion, the activity of Bozja itself is not as active as before. This includes Delubrum Reginae which is the only guaranteed way of acquiring "Timeworn Artifacts" on every run for the quest "A New Path of Resistance", yet it has become increasingly difficult to do so without pre-made parties.
The secondary option is to go into Palace of the Dead, yet in here it is simply a chance to drop the required item. Having gone through floors 1-90 in a solo run to attempt the achievement for 1-200 solo, I have not managed a single artifact to drop.

So, with this information in mind I would to at try and alert the developers about this issue. As you can come to a quick standstill in acquiring your weapon on this step, without a big group of friends ready to run Delubrum with you. While it's certainly easier to do so than before, you still require quite the team to do so within the allotted time, and it would be nice if people could still do it aside from pulling a big party from Party Finder every time.
Quick steps to partially fix this to me would be to either lower the amount of Timeworn Artifacts necessary to complete this step, or make Palace of the Dead clears have a 100% droprate of a singular piece in juxtaposition to the 100% of getting 3 per Delubrum Reginae clear.
