I just made a quick plugin that allows battlers to target enemies with 0% Target Rate. This is intended as a passive state with other plugins or something that an item/skill can apply. It's modeled after the "See Invisibility" spell in dnd. Obviously, this is geared toward combat-use, but you can expand this by creating a common event with a conditional branch if you want players to be able to see "invisible" things on the map.
HOW TO USE:
This plugin is super simple. Just make a state called "Arcane Sight" (or whatever you want to call it), then set the parameter in the plugin to the same state ID.
TERMS OF USE:
Use for commercial or non-commercial projects. Please credit EbonSkolli if you use this plugin.
