3.5none is a blacklist ruleset which started as a joke on /tg/, which stated that 3.5e was perfectly balanced provided you threw out the core rulebooks. This has resulted in the following set of rules being built by me:

• 3e books may be used when no 3.5 replacement was provided
• No classes, races, artifacts, spells, or monsters from the following books:
  • Core Rulebook: Monster Manual
  • Core Rulebook: Player's Handbook
• The following books are completely banned:
  • Core Rulebook: Dungeon Master's Guide
  • Ghost walk
  • Magic of Incarnum
  • Forgotten Realms: Faiths and Pantheons
  • Tome of Battle: The Book of Nine Swords
• Humans are banned no matter what rulebook they come from.
• Third party sources may be allowed as per GM's discretion
