The Aaron said: Another option would be to set up a Roll Table with: 10,11,12,13,14,15,16,17,18,19,20,10,11,12,13,14,15,16,17,18,19,20 That would be the right distribution. If you wanted to be sure that you knew when the hero point was taking effect, you could put [Hero Point] after half the numbers. Thanks, Aaron. I'm not the GM of this particular game, but I'll prod him to see if he'll set up a table for me.
