The official OED character sheet is here! A form-fillable digest-sized PDF that automatically enters ability score modifiers, total encumbrance, and your character's movement rate as you go. Makes prepping new characters for play a snap. Also available as two records on one sheet, good for printing blank copies for players to fill in when replacements are needed.
Monster Stat Blocks
Brief stat blocks for all the monsters in Original D&D, suitable for pasting into adventure notes. Includes Equivalent Hit Dice (EHD) values for encounter-assessment, random monster tables, and XP awards. Over 200 monsters included! (For the raw data in spreadsheet form, see here.)
Tables to generate monsters in the dungeon as per OED level analyses. Suggested as a replacement for OD&D Vol-3, Underworld and Wilderness Adventures, p. 18-19.
Tables to generate traps in your classic D&D dungeons. Keyed by level (for use with the same Monster Determination Matrix in the books, or above). Complete stats to copy-paste into your adventures!
Software tools for assessing demographics, monster strength, creating NPCs, and large batches of men in OED. Plus a link to our Github repository for source code downloads; free to inspect, use, and share under the GPL-2.0 license.
It's everything all in one place, and so much more! We've taken our normally minimalist OED rules and made them "verbose" so everything is as complete as possible. Includes full rosters for character classes, monsters, traps, equipment, encounters, treasures, and more. (There's even clerics in the forbidden appendix.) It's free and open on Github -- get it, modify it, and make a pull request if you think you can improve on it. Click on the link to the left, then the ODT file, then the "Download" button to get it.
