User Summary:
Dangers & Dweomers is a retroclone of Dungeons and Dragons, partway between the original D&D rules and the Advanced Dungeons & Dragons rules, to produce what it calls an "Advanced Basic" version of D&D.
Here are some of the difference compared with basic D&D:
- Assign 4d6k3 to ability scores of choice (rather than 3d6 in order)
- Race is separated from class (races include class restrictions, certain special abilities, and ability score modifiers)
- Classes have some additional special abilities
- Dual-class characters are allowed
- Nine alignments, [LNC]/[GNE] (rather than just three, [LNC])
- No alignment languages
- Secondary skills included (these were optional rules introduced in later D&D supplements, but became core by the Rules Cyclopedia)
- Base Armor Class of 10, with higher values being better (as opposed to a base of 9 with lower numbers being better)
- Experience Points for treasure are at a rate of 1XP per silver (rather than 1XP per gold)
- Aside from monsters and treasure, XP are also available through individual achievements and class-related awards
- Turn Undead table is subtly different (it is listed by Hit Dice rather than specific type, and includes "Demon" rather than "Special" as the highest entry)
- There are schools of arcane magic and clerical domains (which didn't exist in Basic D&D)
- The spell lists are similar, but not exactly the same comparing Dangers and Dweomers and Basic D&D (it's much more like the AD&D spell lists)
- Monsters have Challenge Levels (in addition to the rest of their characteristics)
- Monsters include some non-D&D creatures (such as all "Outsiders", a term which didn't appear in Basic D&D)
- Some additional optional campaign rules are included, some of which were not in Basic D&D
- Treasure is related to Challenge Level (rather than by treasure types)
