People will destroy heaven to create hell simply because heaven was created by someone other than them, and the heaven they live in makes them feel inferior.

The Mansions of Madness dice are gimmick dice that have 8 sides but only 3 outcomes. 4/8 mean failure, 2/8 mean success, and 2/8 are failures unless you spend a "clue" token to make them a success.

You can just use d4s where 1-2 equal failure, 4 equals success and a 3 can be turned into a 4 with a "clue".

1 success for common tasks (50%+ with 3 dice). 2 successes for challenging tasks (33% with 5 dice). 3 successes for barely possible tasks (25% chance with 5 dice)

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.
