@angelsgal It’s worth noting IMO that, aside from CQs being like 1% of the game, Hokusai has a pretty cost prohibitive CQ comp if you actually want to use her for CQ min-turning - literally the video that popularized her had Waver, Bride, CasGil, NP2, and MLB BG (although Superscope is also a necessity afaict in certain other, later CQs). To say nothing of the Abby’s, or Tamamo’s, or even Poster Girl(s) that come into play if you want absolute reliability in cycling out your buffers so that more another can come in and buff then repeat the cycle. Or later, Skadi, as the 50% charge is pretty important for getting Hokusai to NP again (and subsequently NPAA to stack yet more DEF downs).
Personally, as someone that puts money into the game on a regular if sporadic basis, and has had good and awful luck (frigging scopes/BGs not showing), I’m like 75% of the way to being able to run a Hokusai comp if I rolled for and assumed I got her. Ain’t going to assume circumstances, but she’s far from a “Get her, sweep easy-peasy” (even ignoring the fact that all of those cool CQ min-turn videos involve hours upon hours of resets for proper card RNG and whatnot).
Meanwhile, it’s not exactly like she can farm regularly either despite the 30% charge, as an appreciable amount of her refund is built into her Arts crit combined with goofy DEF down stacking. She can, granted - but IIRC you’re looking at at least Bride’s bond CE, to say nothing of some others.
Do I think she’s bad? Nah, she’s pretty lit. I actually adore her character, even. But unless you have certain other stuff in play an NP1 Hokusai isn’t going to simply bring you an easy CQ life, and certainly not as much as say an NP1 Gilgamesh would, by virtue of his powerful hit counts/NP gen/NP being SE against 99% of Servants. In fact, the rates being what they are, your probabilities are more likely that you’ll spend way more to get her than you would by ditching the GSSR, or whatever.
Edit: Here are examples of what she can run and more broadly what it takes for her to 3T, known as the “Hokusai System” in JP.
