When I downloaded Razes fighter (lvl 45 at the gong) and got to whaselands, I invested all his skillpoints. One or two strokes at an imp and he was dead. And he hit REALLY fast. It wasn't even funny. Overpower means you have so much power you're unbeatable (like in Fallout when you'd got the powerarmor AND the plasmarifle. You needed one turn to kill a supermutant and they needed five shots to even HURT you (you were crittically hit for no dmg. The scar will be nice partytalk later in life...)).
