Does Diligence Bonus (10%) Stack With Vega Spell 60% (90%) & Making It 100%?

Thanks alot guys for your replies...

So... erm.... what does diligence stacks with anyway? only 10%, 30%, 60% & 70% scrolls? What is actually being defined as "Special Scrolls"?

Thanks in advance

It stacks with every normal scroll except the pink ones. Every scroll that does something other than adding a set amount of stats is excluded, meaning no chaos, pot, enhance, innocence or clean scrolls etc.
