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.
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)
@Stahesh I've always had a soft spot for Call of Cthulhu as a TTRPG. The books are obscure and rather expensive, but solving a mystery is inherently more satisfying than killing monsters for gold coins to level up and kill more monsters.
I've watched a playthrough of the Cthulhu waifu game. I applaud the originally of combining cosmic horror and a dating sim just for the shitpost value.
@Tfmonkey I like call of cthulhu because cosmic horrors are better compare to average horrors like slashers.
Yes killing monsters get boring easilly when I play Diablo 3 I will need to take breaks or tried metin2 too boring killing same stuff over and over.
I watched someone play Sucker for love and Ln'Eta was good other girls were boring to me.
If you like Lovecraft and fishing you will like Dredge.
@Tfmonkey insomnia is a codeword for autism. Got it.
@Tfmonkey I’ve never played any of these games and don’t plan to, but this is still more interesting than anything voodoo has to say.
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.
