Tired of players who lack fear of death and wade into the thick of battle without batting an eye? Want to add a sense of danger to your game? Do you want your monsters to be MONSTERS?

For years, the Grim-n-Gritty Hit Point and Combat Rules have provided a realism-based alternative to the standard cinematic combat rules of the world's most popular fantasy RPG. Now updated for use with the 3.5 edition rules, GnG 4.0 provides the following:

  • Alternative rules for figuring hit points based on the size of a creature, making massive monsters truly terrifying.
  • Injury penalties which hamper your character's performance as he suffers damage.
  • Armor that reduces damage, rather than lowering the chance to be hit in combat.
  • Opposed rolls for combat, using a Defense statistic.
  • A "Relative Degree" mechanic that replaces critical hits and increases the damage you inflict based on the success of your combat roll, rewarding skill rather than weapon selection.
  • Effect-based called shot rules.
  • Some support for psionic, modern, and future characters.
  • Epic-level rules.
  • Guidelines for adjusting a creature's CR based on its size.
  • A new action type and new defensive actions.
  • New automatic fire, suppressing fire, and energy weapon rules.
  • Over 50 new and revised feats for use with the system, including psionic, metapsionic, and metamagic feats.
  • Martial arts feats for nerve strikes, breaking strikes, and grappling.
  • Four new spells and three psionic powers.
  • New and revised magical and psionic items.
  • Suggestions for implementing the rules in a high-magic setting.
