Kay so I'm still having some troubles on Orin, but I understand how her attacks work now. Mostly.
First nonspell, I just stay around her hand to safespot it ^^
First spell, kinda troubled with it, but I circle clockwise to lure the fairies away, then dash in quickly underneath to deal all the damage I can to Orin.
Second nonspell, stay right below her in the middle to avoid the blue diamonds, stream down, come back up quickly. Works very well and easily.
Second spell, relatively easy. Can't really explain how it would go, but there's only one way, isn't there?
Third nonspell, I'm finally learning a bit. I see that when the bullets are shot the area that looks like it's "leading" is relatively safe until the next wave. Just find a spot to move around in, and dodge. Try to stay under Orin if possible, but keeping alive is my main concern.
Third spell, the rings of spirits or whatever still get me, I need to study their aim more (I know one's aimed at me, but I don't have good enough judgement about the space just between the 2 rings).
Last spell, I'm a huge mess on, I guess it's fairly similar to the first spell, only with tons more bullets. I'll probably bomb this one on sight.
And one little note, I've decided to get back to Reimu-A for awhile (I'll try to get through with her first, then use Marisa-B, since for me it's much harder with Marisa because of her speed and hitbox >~<).
Any tips on Rekindling of Dead Ashes? As well as Needle Mountain, of course. And am I doing Zombie Fairy correctly (well, there usually isn't a CORRECTLY, but there's usually a recommended path or strategy)?
