Here’s a fun dice pool system. I’ve tested it and it works fine. There was a discussion about it at one point on Michael Prescott’s G+ feed, I think, but now that that’s going away I want to preserve it somewhere. Someone else (maybe Michael) started calling it Milton dice so now that’s what it’s called.
- Your attributes and your skills give you a number of d6s to roll.
- The GM sets a target number to hit.
- Roll those dice.
- Add up the results on all the dice, but 4s, 5s, and 6s count as 0s. (So for example, you roll 4 dice and get 1, 1, 3, 4. Your total is 5 because the 4 counts as 0, and you just add up the 1, 1, and 3.)
- If your total is equal or greater than the target number, then you succeed.
What’s cool about this system?
- By only counting 1s, 2s, and 3s, each die has an average result of 1. This is because 1+2+3=6 and there are six sides on a die. It makes things really easy to calculate. If I’m rolling 5 dice, then my average result is going to be 5. Likewise, setting target numbers is easy. A TN of 5 will probably be hit by a character rolling that many dice. It has a pleasing transparency that a lot of dice pool systems lack, as Luka pointed out. The odds are a little funky in the 1 or 2 dice range, but it evens out nicely after that.
- You only have to add up 1s, 2s, and 3s, which makes the addition really fast.
- You can distribute 6 points around a d6 in other ways, like make 1 and 2 be worth 0, 3 and 4 be worth 1, and 5 and 6 be worth 2, but that gets confusing without custom dice. This uses the pips the dice already have.
