the anvil description wrote that it is used to increase the refining rate for lvl
0 ~ 8

does it mean it can only be used up to lv 7 to 8? or lv 8 to 9?

I wanted to refine my weapon from 8 to 9, can i still use anvil of generations?

and it said increase by 10%, does the calculation works by :
a.) base chance% + 10% = success rate%?
or
b.) base chance% + 10%*base chance% = success rate%?

thank you very much in advance, im kinda new in refining
