I've been suggesting that someone make a spreadsheet to crowdsource kurito data. No one has done it yet, but that's ok. I just did.
https://docs.google.com/spreadsheets...it?usp=sharing
Instructions are on the first sheet. Pick a sheet at the bottom, rename it, and start adding data. Even if you only add a few entries, over time we'll get a pretty good database.
I cannot reiterate this enough: Every entry is useful. It doesn't matter if you get the SR card on your first R gacha. It doesn't matter if you feed Kurito 10,000 R gachas one at a time and get nothing junk. The value is when you take ALL the data in aggregate and add it together.
Together, we can beat that damn squirrel.
P.S.
The link is set up so anyone can edit it. Let me know if this is not the case. It SHOULD work, but if not, I'll play with the settings or add you specifically.
