Couple of additions:
Radiant Embers
Because rings are so rare and there is no other way to improve them other than finding a better one, it’s best to focus radiant embers on your rings first. This is the one case where I would not wait for stats to be closer to max since rings can have such a huge impact on your build.
Sublime Embers
It’s best to use the watcher for the first 2 exalts and then these for the last two exalts to avoid using 3 husks and 3 torn marrow.
