Calling it right niow!

Aire Tam Storm makes a return in this game from Final Fantasy 7.

For those who don't know what it is:
Emeral Weapon, a boss enemy, used this move which does massive damage potentially instant kill.

Why you ask? the name itself "Aire Tam" storm is just Materia backwards. For every materia you have equipped you would take 1111 damage. So with 9+ materia equipped you would take 9999 damage.

I am calling it right now, so mob will eventually have a move that will base it's damage based off how much materia you have equipped. Possibly Legatus Darnus.

That... would be evil.

So very evil.

I can imagine the forum rage already.

a lot of potential in that.
Why stop at Materia?
make enemy attacks that deal greater damage to certain gear TYPES.
After all, any class can wear off class gear (at least in part).
Even better yet, apply it to battle phase changes.
