False Swipe Move/Weapon : Certain attack will not drop Pal under 1 HP

[UnDoneCairn]

I was wondering if there was any possibility for a move and/or weapon that functions similar to False Swipe in Pokemon, that would leave a Pal at 1 HP even if you keep attacking it with the same move or weapon?

Just to make it easier to catch things, like how I always used the move in Pokemon. I wouldn't want the effect on all moves or weapons, since that would make catching the only way to resolve combat aside from running scared (my usual strategy works great sometimes), but as an option it would be lovely
