Want to share the playful elegance that is Original Edition Delta with friends and acquaintances, but don't know where to start explaining it? Here's a postcard-sized promotional flyer that you can hand out or email to get the ball rolling. They'll know we mean business!
A concise, digest-sized listing of all the monster Equivalent Hit Dice (EHD) listings in the Monster Database (see below). These have been found by computer Monte Carlo simulations (several million sample combats each). Use these for encounter balancing, XP awards, etc.
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.
All the monsters from Original D&D in a handy spreadsheet (Open Document Spreadsheet, ODS format). Includes OED-style interpretations to fill in any gaps, special abilities, estimated Equivalent Hit Dice (EHD) values for balancing and XP, automatically-generated stat blocks for copying into adventure materials, and more.
