Yes so those alone are very powerful buffs but the 2s additional cooldown reduction is so pivotal because all of the following are affected:
-Purifying Brew
-Celestial Brew
-Bonedust Brew
-Black Ox Brew,
-Ironskin Brew
And then, whenever you use a brew, Special Delivery deals damage too, and the tuning of RJW is too low to make the global worth it imo b/c BrM has so many buttons as is and trying to kite/affixes on top of BoCo on top of RJW is just too much lol (it would be cool if RJW was buffed some to increase skill ceiling, same for WW, as it’s tuned too low there too)
Then on top of that, Bonedust Brew increases the CDR from your abilities even more, creating a positive feedback loop which makes the spec SO MUCH FUN.
So make this macro:
#showtooltip
/castsequence reset=15 Celestial Brew, Black Ox Brew
And use it instead of Celestial Brew on your bars.
The maximum number of brews is to dump all Purifyings (optimally) and use Celestial Brew then immediate Black Ox Brew get BoBr on CD ASAP for cooldown reduction.
This is such a fun fun fun and powerful defensive, allowing you to chain 4 purifying brews and 2 celestial brews.
Since we also have access to the BoCo effects, in a worst case survivability scenario, you could stall red stagger for 6 seconds (each time the next Purifying Brew will purify more stagger than typical, charging up Celestial Brew faster than what is possible with other builds — throw on 3 more stacks of improved Celestial Brew from BoCo) and then you have 2 of those for a total of 12 seconds red stagger stalled and 6 more stacks of impCelestial Brew from BoCo and then the additional stacks of imp brew from pausing stagger to get a safe big purify
For maximum damage:
Weapons of Order Ramp x4 → BOK → BoF → BDB → Ironskin → Purifying x2 → Celestial → Black Ox Brew → Purifying x2 → Celestial → Exploding Keg → SCK (the goal being to cast Exploding Keg to absorb the most Special Deliveries with all of your DoTS up and casting SCK to trigger the burn effect)
But in hard keys like for these fortified keys, using all 4 purifying brews and 2 celestial brews efficiently by staggering them out and do affix/kite/dmg it’s super fun. If there is a tank buster combo you can do it faster pace and react to each part of the tank combo, and then you have your other defensives for the next set, etc.

With optimal BOK Keg Smash and Bone Dust Brew, you can get Black Ox Brew down to roughly 1.2 min, which is super fair.
