Wow, Marisa's options in MoF are kinda shitty.Stop orzing first before making assumptions ._. Marisa's offensive options are <3 compared to Reimu's hoemingming
I'm betting you already know about Marisa-B glitch (and it's obviously the easiest to use) so I'm not going to elaborate on that,
but Marisa-C actually has the highest power output (not counting Marisa-B3 glitch) after many testings. I'm just receiving so much points compared to when I use Marisa-A, which I believed before to be the strongest, but Marisa-C, with a lot of front-row practice, is some kind of powerful right there...
...except in cases where you fight something like Momiji which kind of doesn't give you time to even place those orbs, well anyway she just has that 'bomb on sight' vibe anyway ._.
