Yeah, but what if you want to use a GF that has a certain elemental attack so you don't completely kill an enemy?

If you're stronger than they are, and don't have item or magic junctioned, it can be sorta hard to take off hp without killing them. Solution? use quezacotl and shiva and the early ones and don't boost them.

one of my proudest accomplishments was boosting queza up to about 158. shiva doesn't get nearly as far, and hasn't yet.

But really, it was just a way to add interaction, at the cost of the tip of my left thumb. (it gets jammed really painfully into Select)

although it feels sorta cool when the vibration starts up and it rattles my teeth. because I have the other end of the controller against my chin. *shrugs* it's a fairly effective way of boosting.
