I used an angelic crucible on Krysbin’s Sentence. I got a message saying it’s already equipped. I salvaged the extra one I had, have no rings equipped, and I’m still getting this message, even after closing the game and restarting.
Edit: also m a dummy. Didn’t realize only one sanctified item can be equipped at once.
Considering sanctified items are unlikely to transition to non-season or revert to true primal status, it is best to Crucible an item you do not intend on keeping but need for the build anyway. In my case, I generally Crucible the weapon I want as 1) it is obviously required and 2) they are very easy to target farm/upgrade.
