1 brick per; used 1 already for Apocalypse lance, will need 1 more each for Typhon lance/Garuda hammer*/Phoenix bow. If I end up rolling a kamihime with a strong weapon, I'll adjust plans. But until then, that's my intended use for the next few bricks.
Typhon lance is near certain; I'm not waiting another year to throw away another week of farming to end up with nothing yet again. I also won't even be attempting any gacha rolls until mid-late May, which is another tower later. So my kamihime weapon situation will remain the same for a while.
Garuda reprint won't actually run until late July, so it's more like I'll be earmarking one brick for the hammer in case I fail to get a copy to drop. ~800 HE's over the course of Phoenix/Apoc/Typhon couldn't get me a single drop, so I'm pessimistic about Garuda. So I'm planning for a brick here. At any rate, RNG seems to be dead set on making sure I never see a wind SSR hime (or dark for that matter) in this game.
Phoenix bow is the one that has the strongest logical argument to be pushed off to later in order to keep some bricks around; light gets plenty of assault/defender weapons. My light team is comparatively loaded enough that FLBing another bow won't make much of a difference.
But fuck that. It's been half a year since that reprint and I'm still pissed about the farming turning up nothing. I will not be mollified until I FLB that second bow.
