A long while ago, I saw a post on a possible D&D 5th Edition DW Hack.

A long while ago, I saw a post on a possible D&D 5th Edition DW Hack. More specifically, it was dealing with how you might go about adapting the d6 0-6, 7-9, 10-12 roll results mechanic to the d20.

Does anyone remember that post?

I suspect the math wouldn’t quite work out, but thoughts are appreciated.

1. You could certainly make the math work in 5e. I’d do an array of selected scoreselecteds or the raw point build

2. Would you adapt the d20 roll and categorize the moves according to how close or far away the roll was to the target DC in either direction?

3. Don’t know the post, but the math for straight DW is this:

Chance to roll 7+ is 58.334%

Chance to roll 10+ is 16.667%

So on a straight d20 roll, the closest is 11+ (55%) and 18+ (15%), respectively.

If you used 5e’s Advantage mechanic, though, you get a bit closer with 14+ (57.75%) and 19+ (19.00%) respectively.

If you used 5e’s Disadvantage mechanic, you would need 6+ (56.25%) and 13+ (16.00%) respectively.

Hope that helps.

I know that 7 to 9 is not the same as 7+ in regards to results, but for the purposes of determining odds, it was easier to demostrate.

4. Er that was supposed to be in my Google window… I’d map a straight d20 to 2d6 probabilities. Give a negative 1 to the roll for every 5 points the in the book DC is greater than 15

5. Thanks for the feedback and suggestions. There’s so much to love about DW, but for me the biggest is the fail/partial success/great success mechanic. No turn seems ‘wasted’ where either you did a thing, or didn’t do a thing.

6. Victor, I need some clarification. Either you had a typo, or I’m missing something. You are subtracting 5 from the TN or AC, correct? In your example:

“Another example would be you need a 15 to jump across a cliff. On a 11 or lower you fall. On a 11-14 you succeed with a setback/price (maybe hanging from the edge), on a 15 or more you succeed with additional effect.”

“On an 11 or lower you fail.” Shouldn’t this have read 10? Other wise, there’s really no way to fail on an 11 or lower, and also partial succeed on an 11-14.

7. Jeremy Strandberg that’s perfect for my use. Thanks for posting.

8. Jeremy StrandbergÂ Thanks so much for the post. Helpful indeed.

9. What’s this ‘turn’ thing you speak of?

10. Jeremy Strandberg

Â Yes. This is excellent. Thank you.
