Luster Class Discussion

[Tigy]

People are just confused because of Gunslash Ability Plus.
It doesn't use the the affixes on allyour gear, just your weapon. It's basically so that if you have an s-atk affixed gunslash you want to use for something else, can still use it for Luster. It works like the Et one for wand. It basically just uses the S-atk affixes on your weapon for your R-atk if they're higher.

Yeah it said so there, that skill only use satk affix on weapon just in case the satk affix is bigger, meanwhile any source of satk outside it is meaningless.
