You only need to create the effigy once on a given character to be able to repeatedly summon the Many-Faced-Devourer that drops Uuna's doll, so if you don't get the drop, you can try again the next day without needing to collect the Call of the Devourer and bones again.

Right now (right after 7.3 launch), as with most Argus rares, you should probably be a tank if you intend to solo the Devourer. This will probably change as our gear continues to climb toward the end of the expansion.

Just reached Concordance on my monk tonight and picked up this pet. When you have her out and mount up on Ban-Lu, Ban-Fu will have an animation above her that matches the now removed monk buff, Legacy of the White Tiger. She will also run over to other monks who mount up on Ban-Lu. The only other activity I've noticed is that when idle for a bit she'll lay down and take a nap. She will not sit on your lap when you /sit with her targetted like most other cat pets do.
