It's been over a year since WL9 was released. What are the true odds of getting 4 materials vs 3 from Overworld Bosses?

I've looked it up multiple times every couple weeks and I've yet to find an authoritative answer. Some people guesstimate it's 20%, others say it's 40%, and some *swear* it must be 0% (skill issue imo). Anybody know if anyone's done data-gathering with ample sample size?

[Wiki table for reference. Notice how it stops at WL8.](https://preview.redd.it/l0to7gqxo2cg1.png?width=587&format=png&auto=webp&s=8189043e4285d1af8ca17863c6090100bf515362)

when you accidently click on redeem: 100% 4 drops

when you need to urgently upgrade a character for onslaught/ abyss/theatre: 3 drops

When at 45/46 drops = 100% 4 drops

And when at 42/46 always 3

40% really seems too high from personal experience, doesn’t it?

And normally I wouldn’t say personal data is very convincing, but as a disclaimer, I have **six accounts all at WL9**, and have been farming bosses on them since WL9 has been out (so about a year). I certainly have **NOT** gotten 4 boss drops 40% of the time, not even close.

**However**, doing some math you can start to realize that… maybe 40% is the right number after all? Maybe there’s something funky going on here.

At a 40% rate, you can expect an average of

(4 * 40%) + (3 * 60%) = 3.4

mats per fight. In order to max out one character under these assumptions (46 boss mats), you will need 46/3.4 = 13.5 boss fights. And actually… this kind of tracks.

Assuming you did 14 boss battles (because you can’t do half a boss battle), you’d only need 4 of those battles to drop 4 mats instead of 3, to get your 46 mats. And well, that’s closer to 28% of your battles. Kind of weird how that happens.

This is all anecdotal however; take this comment with a grain of salt.

When you have 19/20 mats and miss that last one? 100% of getting 4 mats.

When you have 16/20 mats? 0% of getting 4 mats.

I've farmed Nod Krai boss mats for 9 characters (two accounts) to lvl 90 and have generally gotten one 4drop each. I think it happened twice with the Moonfly and twice with Bobik. Im not sure how that tracks percentage-wise but it's not great.

from my experience it's about 5%. Maybe 10%. With no pity system. So you could go for your 46 without getting a single 4 drop.

It feels like somewhere between 10% and 20% to me, I don't have a basis on that other than feels, and therefore i am probably wrong.
