TL;DR - If you want to use a Dungeon World 📖 move in Dungeons and Dragons: Fifth Edition (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 5E. Dungeon World has the following probability based on:
| 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% |
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.
| 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.
