Littlest Brown Book With Clarifications And Additions

fom Gygax (early years only), Holmes, and Philotomy.

We'll stay minimal but just go a couple of steps further than Littlest Brown Book.

Also, let's convert all those inch measurements to feet.

If you'd like to contribute, have a look at the To Do list. You can also find me in the OSR Discord.

Current focus

Add bits from Philotomy's Musings

To do

  • Split book into 3 (or 4) parts: (Player Book), Spellbooks, Referee Reference, Campaign Creation
  • Only include house rules that are very close to OD&D as written. Rules that fill in gaps. Rules that one might easily imagine early referees using. Philotomy's Musings are generally suitable.
  • Read through Holmes.
  • Read through various Gygax articles.
  • Have a look at Delta's rules.
  • Find out if any of my own house rules or Idraluna's may be derived from/cited from an early source.
  • Consider Smoldering Wizard's OD&D Elf.
  • Consider Philotomy's Movement in Combat and 10 second combat round.
  • Consider Holmes' exploration movement speed as a house rule (described by Philomy's Movement While Exploring)
  • Anti-cleric reversed spells aren't listed
  • Holmes features a reversal for Purify Food & Water (Contaminate Food & Water) on the Cleric List,
  • Shields sundering
