I got an error when trying to use it because of another script that is a patch for Individual equipment and the Runic enchantment script. The Rune is in there because it is both an armor and labeled as Rune. The line looks like this.
when :armor
(item.is_a?(Game_CustomEquip) && item.object.is_a?(RPG::Armor)) ||
(item.is_a?(RPG::Armor) && item.is_rune?)
Even if you remove the bottom line it'll still display under armor. I did manage to get it under items though.
when :item
item.is_a?(Game_CustomEquip) || (item.is_a?(RPG::Item) && item.is_rune?)
Is there anything I can do so the Runes are just under items?
