On those boring days...

Emerald wipes me out with this laser beam that takes off around 7,000 per hit

Use less materia!

#ofMateria x 1000 = Damage from Aire Tam Storm

It can be used for your benefit, though. If you have an HP plus (or two) on Cloud/Barret/Cid to get their hp to 9999, and only have two materia per person equipped, it'll be nifty if he hits you with Aire Tam (With you having full hp, that is. That's the hard part). With 7777hp, your character(s) will go berserk and start slapping him/his orbs for 7777 damage I think... 15 times. Plus, if you've got Omnislash, Ungarmax, and Highwind limit breaks on (and ready), each hit from those will do 7777. So let's see.

If he's got none of his orbs out... you'll hit him for (note: I'm not 100% sure of how many attacks Omni/Ungar/High do.)

45 x 7777 + 16(Omnislash) x 7777 + 20(Ungarmax) x 7777 + 18(Highwind) x 7777 = 769923 damage. Ouch. That's a big knock off his million HP.

And then, as long as your HP remains 7777, every hit will BE 7777. But lose 1HP, and you're back to base damage.
