Swords & Wizardry
Swords & Wizardry is a clone of the original Dungeons & Dragons. S&W: White Box recreates the very first release of Dungeons & Dragons. The Core Rules adds much of the content that appears in the first few Dungeons & Dragons supplements. You can download a free copy of either edition here.
I'm currently (Mid-2011) running a White Box campaign. All of the following was created for that campaign, but may be applicable to the Core Rules as well.
- Hit Points - Graphs of HP probability over level per class, comparison to traditional D&D way of rolling.
- Numbers versus Experience Points - Graphs of Level, HD, HP, BHB, and ST versus XP
- Swords & Wizardry Rules - The rules in properly styled OpenOffice ODT and Microsoft Word DOC formats.
- FRR Swords & Human Wizardry Campaign - 2011- Forgotten Realms Revisited Campaign
- Monsters by HDE - The monsters from Swords & Wizardry White Box, sorted by HDE. Useful for identifying level appropriate monsters.
