General

if you have the money or you know you can get more, go for the 19 att mask, potential it, and cube it til you have luk % close or higher than 8%

%luk gives more damage as base luk goes up and when it reaches the max of 999, 1%luk is the same as 2atk.

so the 19 atk will be better than the 8%luk.
