Battle mage guide

Is it easier to use The Finisher and teleport on 4-5 Blow? Cause when I was trying to Triple-Tele-Finisher-Tele (cause I 1hko everything with Triple, the Finisher is useless unless I teleport to new mobs), it didn't work a lot of the time.

Finisher is a touchy move. Make sure you've let go of your directional key before you fire it off, holding it will usually ruin the opportunity to use it. I've also been able to walk with it a bit before I used it, though I'm not too sure exactly how this happened. I was using it in 2nd job consistently the way you describe though, but only once I made sure to let go of my direction key after the tele prior to it.
