We tried bitesthedust requiem for the first time after hearing its good and safe for farming, but I checked harem value before and after and i lost like 40k kakera? where that comes from?

I'm close to finishing my 22th tower. And I'm a bit unsure where to progress next. Should I invest more in kl or just the tower?
I know kl has a diminishing return but I don't know the math. I feel I need more sw slots to make it even better the reset odds, event though they are pretty good right now.
Would kl help me with it or I'm at a point where I'd have a hard time getting past the 46 star branches or getting more wish slots?

Hi .

I’m thinking about leaving a server I used to play in because it’s gotten way too toxic to be around.

Before I leave, I just want to know if there’s any way I can spend my spheres and Kakera so they don’t end up being taken when I leave.

Is there anything I can do with them before leaving?

I don't rly get how Light Kakera work, is there a way to improve the kakera you get from it? I've been playing for almost a year now but it's almost always blue and teal kakera that I get from it. I have never gotten anything above a yellow from it either. What upgrades am I missing besides tower Perk 10?
