But if redirecting magic nastiness is lawbreaking, then I'm gonna have to go look at Proven Guilty again. I thought it was standard WC practice to bat back incoming bad stuff.
You're probably right but I was just kidding. Lawbreaking conversations can get a thread widely off topic.
But if you beat their roll in order to redirect, are you using the original roll or new roll in the final stress count? Also, why couldn't redirect be the same mechanic as riposte? Is there a difference between them besides target? If there isn't, why differentiate?
And if everyone is giving up their turn, then of course it can go on infinitely. The PCs smack back an attack, the BBEG + flunkies turns it around on them, and the two sides just spend each round doing nothing but sending the attack back where it came from until somebody rolls a -4 and everybody on their team is out of tags. That's a potentially indefinite series of redirects.
With riposte, one guy attacks and another defends. If the defense beats the attack, the defense becomes an automatic attack on the first attacker. The amount of success depends on the difference of shifts between those two original rolls. You don't make any extra rolls. That makes it hard to include a third person.
That said, you could do as Dragoonbuster suggested and have the 3rd person make a defense against the original defense roll(since that defense roll has become the attack).
With Step into the Blow (which I'm suggesting you use), if you fail to defend, you get an immediate attack against your attacker at +1.
I'm suggesting that, if you dodge, you get an immediate attack against another person in your zone using the attackers weapon value. You have to give up your next turn to do it. So you can only do this 1 time every 2 exchanges.
Example:
Ogre swings club at Bob.
- Bob defends, re-directs club at Alex (Bob rolls an immediate attack and uses the Ogres weapon value)
- Alex can defend. If Alex also has the stunt, he re-directs at Thomas. (Alex rolls an immediate attack and uses the Ogres weapon value)
- Thomas rolls to dodge. If Thomas also has the stunt, he re-directs at Bob. (Thomas makes an attack roll and Bob gets to defend. Bob has already used up his next action, so he can't use the stunt again. If he successfully dodges, then the attack hits no-one).
This scenario would be coolest (and most like a bugs bunny cartoon) if Thomas re-directs the attack back at the ogre and the ogre smacks himself in the face.
On the next exchange, Alex, Thomas and Bob can't act. They've all given up their action for that exchange. It, therefore, goes straight back to the Ogres turn and the whole process starts again.
