rare mob can be found in Bastion
To be able to talk with this rare mob you need to be a spirit (dead).
So, when you dead and get to the spirit healer the rare should be nearby (if its alive ofc).
Speak to it and accept the challenge. It revives you and you can kill it like any other mob.
While alive you can check if rare's is up - if you see a debuff on you Ominous Gaze
its here, so you can go to die.TomTom coordinates:

Got this today after channeling Kyrian anima to the Temple of Purity and doing the little treasure there. The treasure icon disappeared and it came in the mail with anima and vendor items.
Anima Conductors: Guide to Covenant Sanctum Improvements - https://www.wowhead.com/guides/anima-conductor-covenant-sanctum-improvements-shadowlands
I read through this guide and the part that caught my eye was -
Purity's Pinnacle - Channel anima to Purity's Pinnacle, allowing access to a special treasure
Temple of Courage - Channel anima to the Temple of Courage, allowing you to fight an enemy champion
I am guessing the 1st commenter was referring to this.
We need to upgrade our anima conductors and this sword may likely be obtainable if we're part of the Kyrian Covenant.

Found this video on youtube, explains what to do and how to get there.
Who knows what the drop chance might be. Best of luck!
