Scrolling question

Wih the new cash shop specials I was wondering if I can have this combination to scroll an item:

a: Sheild Scroll ( protects slot )
b: lucky day
C: protection scroll
Can I have all these together on an item

In addition I would like to know if the perfect innocence scroll will return my item back to the same stats I bought it, cause I think my staff was 2 above avg.

I'm sure you can have the lucky day and protection scroll on an item. Not sure about the Shield scroll, but I don't see why not.

And innocence scrolls return your item to average stats. So it won't be overaverage anymore.

They all stack.

Does the +10% scroll success rate from diligence stack on top of lucky day scroll?

Does the +10% scroll success rate from diligence stack on top of lucky day scroll?

There's no way to prove it does, and i haven't seen any proof that it doesn't (which would be video of an 80-89% scroll failing - not sure these exist, either)

My inclination is that trait effects are only working sporadically anyway, I wouldn't count on them helping.

I believe that it does, but like Stereo I don't have any actual proof.
