So Apollo 13 has a set pattern whose only change is Eirin's position?
Not entirely, it's offset by a random degree everytime you go against it, but the bullets do come out in the same order and will make the same pattern. So the only
two changes are Eirin's movements and the random degree offset, which probably happens everytime she fires the pattern, but might only be called at the beginning of the spell (either way you won't notice it after the first pattern, so it doesn't matter).
Erm, Baity mentioned that the safespot is infinitesimally small, which is not true. It exists and is more than attainable on hard and lunatic, but it really not worth going for since the pattern only takes a few tries to read anyway. Plus you don't need that wussy safespot shit.
I do agree with donut though, the fight is a bunch of bullshit and I am so glad that you don't have to go through it much, compared to some of the other things you could be doing with your time spent playing IN. Can't see shit, captain.
