I read BoWaP every time as well. I wouldn't advocate memorizing it entirely, but knowing it's static can still be useful for perhaps memorizing the occasional dodge (like knowing where to position yourself after you have to do one of those unfocused swings).
Dipper Creeping Close: I try to stay as close to the "four corners" method (should be self-explanatory) as I can, although Murasa's partially random movement can easily screw that up. Generally, I find that the quicker you make your circles around the screen, the safer the card will be (since this will spread out Murasa's appearances more throughout the field rather than "streaming" her and causing her to clump up a fuckton of bullets in one area). Naturally, this comes with the cost of being likely to make a mistake if you're being a bit reckless and moving too quickly, but if you can keep in the rhythm of the four corners, you can circumvent that risk with a lot of 90-degree angle dodging. If you find yourself starting to stream her and clumping up bullets, make use of any wide open gap you see to distance yourself from that area (I tend to see these when I make a transition from a right corner to a left corner or vice versa).
Noncard 3:
have a timeout (as a bonus, the replay also demonstrates the four corners method for Dipper). I use the same general movements for each wave, which is to align myself with Murasa, move up a bit for part of the wave, move back down, move left, then move right. By now, Murasa will have moved, so I follow her and realign myself to repeat the process. Naturally, it's not that simple, but either I boil it down to that or just tell you to read and dodge and deal with it. I still read it, but those motions form the foundation of where I search for holes in the pattern. I don't know how best to clear Vortex bullets so they don't interfere. I imagine there's likely an optimal time to kill off the spellcard, but that's something you're better off asking Baity about.
What I'm more interested in is what the noncard would look like if you flew above Murasa during Vortex, got her to fire upward bullets, killed off the card, and took on the noncard with upward bullets flying from the bottom of the screen. By the way, did we lose spoilertext with the forum update?Ghost Ship: as far as I'm concerned, it's luckshit.
Ignore all instances of spectacular fail in that replay. I'm tired. Of course, if I can still timeout noncard 3 in this state (took me two tries), it should lend some credence to me actually having a method to that madness.
