Basic Dice Mechanic

Unlike standard WoD mechanics, there is no additional relevance to 1 or 10 on the die. That allows results to be compared to the following chart without rolling:

Difficulty
Dice 1 2 3 4 5 6 7 8 9 10
1 1 1 1 1 1 1 0 0 0 0
2 2 2 2 1 1 1 1 1 0 0
3 3 3 2 2 2 2 1 1 1 0
4 4 4 3 3 2 2 2 1 1 0
5 5 5 4 4 3 3 2 2 1 1
6 6 5 5 4 4 3 2 2 1 1
7 7 6 6 5 4 4 3 2 1 1
8 8 7 6 6 5 4 3 2 2 1
9 9 8 7 6 5 5 4 3 2 1
10 10 9 8 7 6 5 4 3 2 1
11 11 10 9 8 7 6 4 3 2 1
12 12 11 10 8 7 6 5 4 2 1

And for your reference on things where it’s a purely pass/fail, here is the chance of getting at least one success (e.g., if there are people trying to resist an area effect, this is roughly the percentage that will pass):

Difficulty
