For those who are using the Equip Battle Skills plugin, you may have noticed that the ‘Skills’ command replaces all skill types in the battle command window. For those who’d like to have certain skill types continue working, you can use this plugin to create an exception for it. The skill types found listed in the plugin parameters will be given an exception and will be shown in battle. Any skill that contains the skill type also cannot be equipped in a battle skill slot.
