Changes Proposed

• allow to specify more than one equipment slots.
• return the total of refine of specified equipment slots.

Shorten this

.@r = getequiprefinerycnt(EQI_SHADOW_ARMOR)+getequiprefinerycnt(EQI_SHADOW_WEAPON)+getequiprefinerycnt(EQI_SHADOW_SHIELD)+getequiprefinerycnt(EQI_SHADOW_SHOES)+getequiprefinerycnt(EQI_SHADOW_ACC_R)+getequiprefinerycnt(EQI_SHADOW_ACC_L);

into this

.@r = getequiprefinerycnt(EQI_SHADOW_ARMOR, EQI_SHADOW_WEAPON, EQI_SHADOW_SHIELD, EQI_SHADOW_SHOES, EQI_SHADOW_ACC_R, EQI_SHADOW_ACC_L);

	mes ".@new_refine = "+.@new_refine;
	close;
}

Issues addressed:
reduce the need to use multiple getequiprefinerycnt(...), kRO tend to introduce new equipments that has combo bonus affected by total number of refine of several other equipments.

Known Issue:
Return value will multiple if users happen to input same equipment slots in the script commands. Ex:

getequiprefinerycnt(EQI_ARMOR, EQI_ARMOR); // value doubled due to duplicate equipment slots
getequiprefinerycnt(EQI_ARMOR); // everything good.
