Editing Open Ended D10 (section)

== Fine Grain (Optional) ==

If you feel that you need more precise scores for attributes you can use a decimal number, as in '5.3'. When you need to test the attribute score just roll ignoring the decimal (in the example roll under or equual 5 to get a success). But, if you happen to roll and miss by one single point (in the example getting a 6 in the die), you can try to 'push' your attribute score for that roll only: roll another d10 and if you score equal or under the decimal number (3 in the example) you manage to success (so, if you roll a 2 you 'push' your attribute score from 5.3 to 6 and thus get a success).

This fine grain system is probability-wise equivalent to rolling a d100. I just think it's faster and more interesting to roll dice this way. You can also combine both regular and fine-grain attributes with this system, focusing in the more interesting things.
