Problem with Alchemy (DC When +)

Hello guy's
my Alchemy is working very fine till +7
when i make +8 if it success i got DC (Not crush)
if it failed i didn't got a dc !
them problem with all degrees
how can i solve that ?

Check _RefItem the upper 2033 -2044 if the param go't +1 to what + you want.

for sure u try to make alchemy rate and u mess up somewhere.
