Baseline D&D Combat Simulator

For my final post of 2018, I am posting a link to a DnD combat simulator.

While having two combatant whack at each other until one of them is dead is not very realistic in terms what goes on in a campaign. It is a useful baseline to have while designing a combat system.

The source code for this can be downloaded from.

I developed a similar utility to use with a Majestic Wilderlands RPG based on Fudge and confirmed the feedback I got from my players that a +1 advantage seems to tilt the odds by a lot. No matter how I tweaked the combat procedure the steepness of the bell curve of 4DF dominates how bonuses work.

Ironically it wasn't until two years later I found d6-d6 fixes the issue as the bell curve is now the same as rolling 2d6.

With this utility one get a rough idea of how the changes over various DnD editions effected combat by plugging the various numbers as they existed in ODnD, ODnD+Greyhawk, ADnD and so on.

Hope this proves useful for your campaigns and I wish everybody a Happy New Year!

OSR Survey

Brendan S and Ben Milton are two hobbyists with a long history of participating in discussion related to the OSR and classic DnD. They have constructed a detailed survey that looks to be comprehensive.

The link to the survey.

At the conclusion of the survey one can leave additional comments unfortunately I forgot to copy and paste my answer. But the following is the gist of what I wrote.


Irregardless of how people used the label OSR, think of the label OSR, or want the label OSR to represent there are several salient points.

1) There is a group of hobbyists who are interested in playing, promoting, and publishing for classic editions of DnD.

2) To ensure that no one vision or ideal stifles a hobbyist's creative vision the promotion and spread of legal open content is vital.

3) #2 pertains not just to classic DnD but to any system that hobbyists are interested in provided there is legal open content to use as a foundation for sharing.

4) Hobbyists interested in #1 are interested in other things as well. So hobbyists sharing or selling will often have a variety of works in addition to classic DnD including hybrids.


Open Content coupled with the low barriers of distribution enabled by the internet and digital technology ensures that anybody with the desire will be able to get their vision out there either commercially or just to share.

Keep in in mind that the consequences of creative freedom will be messy. Resulting in a confusing kaleidoscope of works along with conflicting visions of the source material. The key to remember irregardless of the results of the survey, that you are free to do what you think is best with the material in the form you think will work for your project. That thanks to the internet and other forms of digital technology you can't be stopped from sharing what you created.
