So then either Hachiman or Wargod work with... um... Slash!

Cloud: "Hachiman Slash!"
Tifa: "What?"
Cloud: "You know. Like Wargod Slash. It's the same thing."
Tifa: "What? Really?"

I'd also really like to see the Confu spell as Myst. Confuse and Bewilder sound lame and Mystify sounds "done to death."
