In a previous thread, we went around and around about whether you can borrow infinite actions, or whether the word "available" means "available in the current combat turn." Finally someone asked the devs, and they said you can only borrow from within the same turn (except full defense, which contains an exception that lets you go one action into the next turn). This thread is not for re-hashing that argument, so I beg you, don't do that. And I'm too lazy to find that thread, you do it if you want proof
So, those of us who initially said actions were unlimited had a problem to deal with: Finishing Move doesn't say that you only get one Finishing Move. You just use it after making any melee attack. If you read it literally, and borrowing was unlimited, then you could make a hundred, or a trillion finishing moves at the same time, and then be stuck without being able to act until, potentially, the end of time. The solution was to "interpret" finishing move to only allow one chained attack, which was reasonable. After all, the devs clearly did not mean for the maneuver to shatter space/time.
However, now that we've had the issue clarified, Finishing Move crops back up. You can no longer do infinite moves because you can never borrow more than four actions. So, chaining Finishing Move to itself is now balanced. Or is it? It seems pretty cool than a person with mediocre strength who could never kill anyone with one punch can attack and then do three finishing moves in a Bruce Lee style combo and knock an enemy out all at once. But then again, a troll exploiting this ability could kill someone with the first punch, and kill their corpse three more times. They could probably end up destroying a car in one action phase.
So. Does the language support it? Or if you're too lazy to open the book like me, is it right (for the sake of game balance and morality) to allow Finishing Move to chain to itself?
