For rolls requiring 2 successes, use the following chart to convert Call of Cthulhu percentiles into Mansions of Madness dice pools.

0% 1 Die (impossible because you can't roll two successes on a single die)
22% 2 Dice
29% 3
34% 4
38% 5
41% 6
43% 7
45% 8
46% 9
47% 10
48% 11
49% 13
50% 17

For 3 successes...

0% 1-2
19% 3 Dice
23% 4
25% 5
27% 6
29% 7
30% 8
31% 10
32% 11
33% 13

The math I'm using is (1-(6/8)^X)/Y

X = the number of dice
Y = the required successes

If my math is off, meh.

Insomnia strikes again. I'm going to convert the dice pools of Mansions of Madness into percentiles so you can convert Call of Cthulhu scenarios into Mansions of Madness scenarios.

Use the following to convert difficulty ratings to dice successes on the Mansions of Madness D8s which have a 2/8 chance of 1 success (not using clues)

25% 1 Die
44% 2 Dice
58% 3
68% 4
76% 5
82% 6
87% 7
90% 8
92% 9
94% 10
96% 11
97% 12
98% 13
99% 15
100% 19

Note that this is only the probability of 1 success.

Men and women are opposites.

Women look for a man with the character of a god.
