How about the old mulitple action peantly from Strombringer. They way it worked there was once you had a 90% skill, you could make multiple parres and riposte attacks, but each one at a -20% penalty (Strombringer used two skills so in mRQ terms we could use one).
I'm not sure how this works. If Jackie Chan wants to split his dodge reaction 6 ways, does he take a -120% penalty?
Suppose Chan has a DEX of 21, and he is fighting a dozen ninjas, each with a DEX of 17. Under the MRQ system, Chan gets 4 CAs and 4 reactions, while the ninjas get 3 CAs each, so Jackie has to split his 4 reactions up 9 ways each to dodge 36 attacks, for a -180% penalty.
Under my initiative system (described in another thread), Jackie still gets 4 reactions, but the ninjas only get two attacks each, unless a few of them manage to squeeze out a third attack with a good iniative roll. So JC only has to split his reactions 7 ways for a -140% penalty to dodge 24-28 attacks.
Also, would it be possible to also split your attacks? The ninjas would probably be able to split each attack up three ways for a -40% penalty. Now Jackie Chan has to dodge over a hundred attacks (138 in the MRQ system, or 72-84 in my own system).
I like the old RQ rule which let a character split an action at 1/2 his chance for each action. This means the ninjas probably can't afford to split their actions more than two ways each, for a total of about 50 attacks in one combat round. But then Jackie Chan only gets about 8 dodge attempts splitting them two ways, or 16 dodges splitting them four ways.
I propose a legendary dodge ability which grants an additional number of defensive reactions equal to the character's Dexterity. So Jackie Chan would have 25 defensive reactions, and splitting them two ways can make 50 dodge attempts at 1/2 his effective skill. Enough ninjas can still overpower him.
The other way to get Jackie Chan would be to put him up against a guy who has a high enough effective strike skill to get past Chan's effective Dodge skill.
Atgxtg once suggested a specialization rule that I've adopted, in which a specialization skill can be added to another skill to determine one's effective skill. This is cool, but I am concerned about its effect on combat, especially the martial arts, since it makes it a lot easier to get an effective skill as high as 200% or higher.
