What if everyone here just logged their finds in the forums? Like say for every item that I find I post what area, enemy, section ID and difficulty level dropped each item? That way after a little time we could have enough information to compile a drop chart? Maybe not a complete chart, but better than nothing.
Just an idea.
I'm just going to throw a couple out there.
V101:
Section ID: Oran
Area: Crater Interior
Difficulty: Very Hard
Enemy: Zu
Drop rate estimate: around 1/350 (maybe more. seems pretty hard to find. I've done 20+ runs looking for another one.)
Heavenly/Power
Section ID: Oran
Area: Crater Interior
Difficulty: Very Hard
Enemy: Dorphon Eclair (note: The quest Claire's Deal 5 is a good place to hunt Dorphon Eclaire's)
Drop rate estimate: 1/5 (not 1/1 because sometimes they drop meseta.)
Update!
Select Cloak
Section ID: Oran
Area: Crater
Difficulty: V. Hard
Enemy: Ze Boota
Drop rate estimate: around 1/300
Black Odoshi Domaru
Section ID: Oran
Area: Crater
Difficulty: V. Hard
Enemy: Ba Boota
Drop rate estimate: 1/400
If this idea doesn't catch thats fine. But it's a good way to log findings anyway.
