Can a character who has the lightning element win against a mirror creature?

[Cortavar]

Pataphysics - Imaginary Science (What we cannot conceive)
Metaphysics - Memetic Science (What we conceive)
Isophysics - Normal physics, but in the literary sense. (Objective reality)
Hypophysics - Quantum mechanics, but literary. (Subjective Reality)
Infraphysics - Null science (The science of nothing)

Paraphysics - A altered version of Meta, Iso, or Hypo.

Examples:

• Pataphysics - Something totally alien to human way of thought. This would be your neverborns or eldritch horrors of Lovecraftian origins. By definition, you cannot conceive Pataphysical concepts.
• Metaphysics - This is thought, basically. Pure concepts such as emotions, honor, philosophy, etc.
• Para-metaphysics - It's where you take normal human thought and give it new rules that couldn't exist. Physical manifestation of thought would be a para-meta concept.
• Isophysics - Normal physics, but the thing is, does any "normal" physics really exist in writing? For example, 20 bad guys shoot SMGs at MC and nobody hits. This is Isophysics. Yes, it is POSSIBLE, but really, did that make sense? So, it isn't "physics", it's isophysics. "Real" physics doesn't technically exist in fiction, because it is FICTION.
• Para-Isophysics - You take physics and add new rules. This is most magic systems.
• Hypophysics - Quantum mechanics, but again, literary. This gets a little fuzzy, because TECHNICALLY, it should only be what is possible, but we don't know what is or isn't actually possible. Basically, on some level of reality, when you get small enough, perception changes reality. To observe is to alter what you observe. Is Quantum Entanglement Communication possible? maybe. We're almost there... maybe. But, we're close enough to assume that it is, so it would fall under Hypophysics. It's not "Real" Quantum mechanics, but fictional Quantum Mechanics.
• Para-Hypophysics - Quautum teleportation for macro objects. Again, this gets fuzzy. Is this Para-Iso, or is it Para-Hypo? Up for debate, but mostly it is a useful metric for the writer, not a hard and fast rule. I personally put the line at "How hard is the Magic System/Super Science?" Para-Hypo is more SciFi than Para-Iso, IMHO.
• Infraphysics - The Science of NULL. This is another difficult concept to handle. It is the literary science of NOTHING. The absolute lowest end of concepts. Where we are dealing with the absence of everything. No matter/energy/thought, but even empty space has rules, has permanence. So, if you are dealing with REALLY alien concepts about NOTHING, then you are dealing with Infraphysics.

You will note, there are no Para versions of Pata or Infra physics. Why? Because it already IS as Para as we an get. There are no ALTERNATE versions of Pata or Infra physics, because humans cannot even begin to conceptualize what is NORMAL for these versions of physics, much less what an alternate version of them would be.

TL/DR: It's all just a way of breaking down "rules" for fiction so you, the writer, can keep better track of your concepts when world building.

That make sense?

Looks like these things are not mirror creatures, but some kind of magical chimeras...

If they can eat mana from the lightning attacks and that doesn't require direct contact with the victim/battery, then there's not much that can defeat them at all. But if they only have an advantage over the light element and can't eat attacks, then lightning should be a good enough way to kill these things.

A person is pulled into the mirror and is replaced by this creature who feeds on their mana from the mirror. You can bash them on the head, but they regrow the head with the mana from the victim in the mirror.

That's a very tought opponent. The question is no longer whether a mage with lightning element can kill this creature. The question is: how to kill it without too much harm to the person inside?
