FF8 had a system that allowed you to 1 shot (or maybe a few more hits than just 1) everything till the end of the game, fun game! no really, I enjoyed that

Cifer: " I'm a Witch-Knight, you'll never defeat me"

Squall - Attack!

Cifer: "ugh ahrrr....how is this possible"

it was a valid tactic to start each fight with less than 20% HP so you can start with limit breaks
