Just solved!
Applied any percentage plus getequippercentrefinery(<equipped_slot>).
Code Sample:
Be aware that this code is not "NPC Script" structured! It's just a quote sample.
// Example: Increase the Success Refining Chance by +10%
getequippercentrefinery(EQI_ARMOR) + 10;
// Example: Working Refine Chance Applied
if ((getequippercentrefinery(EQI_ARMOR) + 10) > rand(100))
successrefitem EQI_ARMOR;
// Do the equipped_slot dynamically through:
setarray .@equippedParts[1],
EQI_HEAD_TOP,
EQI_HEAD_MID,
EQI_HEAD_LOW,
EQI_ARMOR,
EQI_HAND_R,
EQI_HAND_L,
EQI_GARMENT,
EQI_SHOES,
EQI_ACC_R,
EQI_ACC_L;
// Create an array with all equipped items, except shadow ones
for(.@i = 1; .@i <= getarraysize(.@equippedParts); .@i++) {
if (getequipisequiped(.@equippedParts[.@i])) {
.@menu$ = .@menu$ + F_getpositionname(.@equippedParts[.@i]);
}
}
// .@selection will be the selected equip from the refine menu (.@selection is the dynamic equipped_slot variable).
set .@selection, .@equippedParts[ select(.@menu$) ];
-- Solved!
