Embrava
Reduce che amount tp/tic you get, but keep the Regain in place of Refresh, please.
Also, base duration should be 120 seconds instead of 90.
I don't have much to complain about the Perfect Defense change.
Something that needs serious fixing instead is all the other content.
The reasons why the combination of Embrava, Perfect Defense and other abilities were abused was not because the monster's health was too high, but rather because they have frustrating abilities that one-shot you or seriously make you unable to do anything.
Too many "cheap" strategies the monsters use to reach a false level of high difficulty in the attempt to counterbalance the existance of powerful combinations of buffs on the players' side.
If you nerf such mentioned players' abilities, you should fix those monsters "strategies" as well, not their HP wich hardly matters.
If it's too much work to fix all of those abilities individually, then do a general % reduction to all of their damage.
Maybe it wouldn't completely solve the problem, but at least it would be better than cutting their health by 10%.
Also, why no fix at all to Provenance Watcher and Arch Dynamis Lord?
What about adjusting the "??? floors" jump in Nyzul to make it a bit less random, or to make it possible to jump a higher amount of floors if you're lucky? Or to increase the minimum amount of floors you can jump through that command?
Stuff like this is what's needed to fully compensate for the nerf of Embrava/PerfectDefense and reach a final scenario where things are, hopefully, even more balanced than they were at start.
