Ubiquity uses a dice pool mechanic where all even dice are successes. This could also be simulated by numbers over half being successful. they key is counting the number of successes, rather than totaling the dice. On a PBP forum, I have simulated it by rolling "x d2 - x", this will give the number of 2s rolled out of the total. D2s do not seem available in the dice roller, so I was trying to figure out the best and easiest way for myself and my players to roll. I do not know if a macro or API would do the job. I know that you can roll in the dialog box, so I suppose it could be done there, but I would prefer the ability to say "roll 10 dice" and the players can do it easily and quickly.
