Some reroll questions.

[Ape]

I just tried to do a search for some information but did not find any.
What i was wondering is:
-How much reroll chance do: Big luck, bigger luck and big lucky hat give?
-What happens when you get above 100% reroll, does the rest become useless as you will reroll anyway?

I think big luck is about 12-13%. I am not sure tho.

When you get above 100% reroll, the game gets funny. Instead of dropping purples, which would then be transformed into pinks, you drop greens , (i think greens is below purple or is it yellow?), which are then re-rolled into purples. You can check this out in nuri, it is hilarious. I had no combo on and i was dropping only purples from bosses, while the 100% re-roll guys were re-rolling into purples. Haha!

Bigger luck is a little more, i'd say about 15% but don't know the exact number...and everything above 100% luck is useless, but no idea if it has a negative effect...never heard of any negative

Devs hardly ever answered our questions on exact % except for asomers.
Players (redbridge) have done their own testing and Come up with their own ideas, and Sam has only said vague things like "bigger is slightly better that big"
So our best guess is
Big 12 (confirmed)
Bigger 15 ( best guess, but some player tests show slightly higher)
Can't find info on big lucky but I guess it's the same as bigger, as it was basically a reskin.
No one know for sure which stack and exactly to what %.
The best luck % from any vanity was the pa's vet hat and that was 30% for one weekend only then was stripped after Memorial Day weekend.
