Anyone and Everyone Scopes?

I honestly searched before I posted this, I know there's probably a topic like this out there already, but I honestly couldn't find it. If the relevant topic does exist, please link me to it.

I want a couple of skills, items, and spells to have scopes that don't discriminate between enemies and allies. Those scopes would be "anyone" (Such as being able to cast a healing spell on either enemies (to invoke the "revive kills zombie" trope) or allies) and "everyone" (such as a "Self-destruct" attack that damages all enemies and allies and may or may not harm the user as well.)

I'm pretty sure these kind of scopes are impossible do do without scripting (If they aren't, please tell me how to do it, because I don't see a way.). So can someone please help me with this?

You should probably make these scopes with Yanfly's Lunatic Target Scripts, but I'm not using them just yet, so I can't help you in that regard. I find it too complicated to use it for now. Maybe if I get more experience... and time.

But there could be some other scripts around which are probably easier to understand than those Lunatic scripts.

Inverting the target scope, aka changing between enemies and allies with a single button press is available with a script. Just search for Invert Target, and you should find some scripts here.

Multiple effects triggered even on different scopes (one on the enemies and one on the allies, for example) is available through another script. It is called Skill Links, or something similar, I don't remember it's name, nor the author, sorry, but with this one, you should be able to make anything you described above, in theory at least, I did not try it yet, but it is on my list.

Random skill invoke (define a skill which can invoke multiple other skills with a random chance) is available also with a script. This one is called Random Skill Invoke from Yanfly.

Than somewhere I saw some other interesting scopes, like: underground, underwater, flying, back row, front row, and maybe some other scopes, all in one script, but again... I don't remember where, sorry. >.>

Combining these it should be possible to make what you want.
