100% to 0% Rani Brew strategy

[ThaiChi]

I've brewed Rani on my NIN several times already. My LS generally goes the brew route after we find Blue !! so we don't waste 15-20 min just whittling it down anymore so we can get more rings out. And my LS has been lucky and for the times that we've fought Rani it hasn't used its charm move while we brewed *knock on wood*. Basically if you're paying attention, you can just switch between Jin (or Hi if you have it) and Yu. It's simple enough, if its using a TP move, you use Blade: Yu. If it's casting (which will give a lot more room to spam physical WS) you can use Blade: Jin. Rani tends to alternate between the two, casting and tping. I might actually have the absorb order mixed with pantokrator though, but healing it once isn't going to kill you. 3 minutes is more than enough to kill Rani and still have time left over to run around 1 shotting the dolls in the area for laughs, just don't get into the mindset that it needs to die within seconds of you popping the brew, just stay calm, watch its animations and you'll actually be surprised how overblown the difficulty on Rani with brew is. A group kiting Rani around my exp party around there ran it into our sleepga range while I was xping my SAM. It started killing our party members and I popped a brew to kill it from 100%. I frantically spammed Gekko not remembering its healing properties and my brew ran out at 2% or something, it was easily the biggest waste of 3 mins of brew time I'd ever done.

But just to go over the specifics you asked for: you don't really need stuns and you're totally fine with RR + 2 other DD/mab atmas of your choice (I have standard set for a Blade: Hi NIN -- GH/RR/Apoc). It should only really take about 1 minute to take Rani down from 100% to 0, so you'll have to gauge how often you're able to heal it for margin of error, but as I said earlier if you're paying attention you won't really ever heal it. You're fine with Katanas, don't need daggers or anything fancy, Blade: Yu does fantastic damage while under transcendence -- around 12k I think, don't quote me on that because I might be confusing with Shinryu or Pantokrator. Blade: Chi is interestingly also decent as a magic WS, did 19k to Shinryu before. No extra buffs are needed, the brew, I've been told, automatically puts you at 999 subtle blow. The only thing I might warn about is using the same WS back to back, Jin to Jin, Hi to Hi, etc. Its constantly changing recovery with the tping and casting will inadvertently cause you to heal it with a skillchain, drawing out the fight longer than you'd really want it to be.
