Porting Apocalypse World style moves into D&D 5E

TL;DR – If you want to use a Dungeon World move in D&D 5E, roll 1d6+1d10: Failure on 8-, partial success on 9-12, success on 13+.

I love the Apocalypse World engine moves. These moves are discreet rules that are portable from one AW Engine game to another.

But I’m exploring using the moves in other systems; In particular D&D 5E. Dungeon World has the following probability based on:

Roll 2d6
Bonus Failure (6-) Partial Success (7-9) Complete Success (10+)
-2 72.2% 25.0% 2.8%
-1 58.3% 33.3% 8.3%
0 41.7% 41.7% 16.7%
1 27.8% 44.4% 27.8%
2 16.7% 41.7% 41.7%
3 8.3% 33.3% 58.3%

Apocalypse World Engine Probabilities

What follows is what I found to be a reasonable mirroring of the Apocalypse World Engine probabilities. Roll 1d6+1d10. On an 8- failure, 9-12 partial success, and 13+ success.

Roll 1d6 + 1d10
Bonus Failure (8-) Partial Success (9-12) Complete Success (13+)
-3 75.0% 23.3% 1.7%
-2 65.0% 30.0% 5.0%
-1 55.0% 35.0% 10.0%
0 45.0% 38.3% 16.7%
1 35.0% 40.0% 25.0%
2 25.0% 40.0% 35.0%
3 16.7% 38.3% 45.0%
4 10.0% 35.0% 55.0%
5 5.0% 30.0% 65.0%

I ended up writing a script to run several iterations and compared this to the Apocalypse World engine probabilities.

The d6+d10 is a reasonable approximation. I chose d6+d10 instead of 2d8 because of the flat peak; 7 to 11 has the same probability for d6+d10; Whereas 2d8 has a “pointy” peak.
