Tangent waves his scythe. The anti-matter is banished to it's point of origin.

Tangent holds his scythe foreward. It glows, and an imaginary storm focuses around Xion. Tangent cast mind mastery!

Xion is confused!
Xion is berserked!
Xion is scared!

Xion, try not to use techniques that are not on your spell chart. If you do, I will too.

And that is perfectally fine, as long as you are killed forever with it.
