I will look into it, although I'm trying to work on step 2: or v1.1
Which requires me to merge/add compatibility to my script with Multi-Slot Equipment by Guillaume777.
I tried using the same format, just switching variables to make it check for armor_set, so I could make armor class proficiencies... however with multi-slot, the weapons work fine, because they all can go either left/right hand, and they all can show up in both weapon spots... however, with armors, implementing my script makes the boots/gloves/rings/amulets/belts/cloaks/armor ... all of which are new equipments slots, now allow for you to equip ANY of them, in the ALL armor based slots
I'm ignoring it for now, as I only had 2 armor class proficiencies, and they were not really necessary, but eventually I'll look into making it work right
