MA T'ien Ch'i - a little of this, a little of that and BAM!

I definately wouldn't go picking a fight with those spells, but they're castable by the mages you're buying per Baalz' guide, and you can dial them up in 3 turns of research. And I'll guarantee they're effective against 0prot troops.

You don't have to go chasing them, you just need one proper deployment to convince the Ermor player that the opportunity cost of rushing you is too high.
