Designer's comments: Dangers and Dweomers is my personal spin on Dungeons & Dragons. A complete, free, OGL game. I took the chance of writing it after Swords & Wizardry made its appareance, as a base I used S&W, the BFRPG by Chris Gonnermann and the d20 SRD. As much as possible I streamlined the S&W system, filling what I found as gaps with material from the BFRPG and the Srd. As always my ideal model is the D&D Rules Cyclopedia. ... After a long while I've decided to do some more work on Dangers and Dweomers. I've added to the page THE BLUEBOOK OF DANGERS AND DWEOMERS, basically a return to more Old School sensibilities. this is the version I'm currently GMing the rare times I get to play. User summary: This re-working of the Dangers & Dweomers rules has subtle changes to the rules that lean more towards an old-school gaming sensibility. For example, the section on gaining experience, the original Dangers & Dweomers states that experience is gained for killing monsters, gaining treasure and roleplaying your character. The Bluebook edition of the rules omits roleplaying as a source of experience for characters. it also includes tables for wilderness encounters and a section on retainers & assistants. The section of referee's information has been re-edited as well and the small interior line-art illustrations have been removed, reducing the page count considerably.
