One of the aspects of 3E that always proves challenging to convert (for me) is the Difficulty Class. I've been learning to wing it with Xin6 chances, per Rient's Rule #1. However, in looking at 3.0/3.5 resources, it seems like almost everything has a DC. Deciding how to adjudicate these can be frustrating because I can occasionally see the utility of making a check, but not the clarity of how to go from DC to something useful in 0E/1E. One of the conversion documents discusses this and included a nice d8 chart:
|SRD Difficulty Class Examples||Corresponding 1E, Basic D&D, D8 Values, roll within the range to succeed. A natural roll of 1 is always a failure. A natural roll of 8 is always a success.|
|Very easy 0-4||no die roll.|
|Average (10-14) -||3-8|
|Nearly impossible (40),||8|
Well, this is nice and all, but I roll with the d6, so I had to modify it for d6 usage. There is absolutely no real math in this aside from an eyeballing of the differences between a d6 and d8. I didn't want to put that much time into doing an exact statistical analysis, so if you want to and you have a good correction for me, I'll edit the post and make the change.
|SRD Difficulty Class Examples||D6 – 1 always fails, 6 always succeeds.|
|Very easy 0-4||No roll.|
|Easy (5-9)||2-6 (5 in 6)|
|Average (10-14)||3-6 (4 in 6)|
|Tough (15-19) or Challenging (20-24)||4-6 (3 in 6)|
|Formidable (25-29) or Heroic (30-39)||5-6 (2 in 6)|
|Nearly impossible (40)||6 (1 in 6)|
Apply +1 for favorable conditions/modifiers, -1 for unfavorable conditions/modifiers
Now admittedly, I'm liable to use this only if there's a question in my head. Nine times out of ten, if it's easy or average, I'm going to just say "Yes" and move on. I usually apply DCs only when things are tough, when there's a good chance of failure and an interesting result that could happen on failure. Having this chart in my back pocket, though, allows me to get through some of the conversions quicker and use the DC/dice to retain the feel when it makes sense. Perhaps you could find it useful as well.
Credit must go to the authors of the conversion document: H.J. Martin, Barrataria, G. B. MacKenzie and Rich Franks.
(And BTW, copying/pasting tables out of Word into Blogger and then trying to edit the table is a nightmare. Blogger needs a better table editing mechanism.)
