The Wushu rulebook:
Speaking of diverted dice, it’s not fair for groups of players to gang up on a single Nemesis. Rolling more dice than the other guy is a serious advantage, so your dice pool limits will need some adjustment when fights aren’t one-on-one.
There are two ways to go...
If you’re feeling ambitious, let the Nemesis rack up a separate dice pool for each hero aligned against them. If two players get 6 dice each, you get a total of 12. Only 6 can be directed against a single hero, though. Fair is fair.
If you’re feeling exhausted, make your players split a dice pool between them. If the Nemesis gets 6 dice, two players get 3 dice each. Three players would get 2 dice each. If that’s not enough, raise the limit a little (you get 8 dice, two players get 4 dice each).
One on One
I know it means “monkey-to-monkey” in Spanish. The wordplay is Latin. Stuff it.
Let's call these two methods "Big Pool" and "Small Pool".
I suspect that the two distributions are comparable, but small pool is swingier. Therefore, my hypothesis is that the choice between big and small pool is merely a matter of style. However, before committing to one style or another, I would like to know whether style has consequences - is there a probabilistically significant difference between the two methods?
