Writer: Kenneth S. Hood

49 pages, 100% open game content


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.


Note: The Grim-n-Gritty Hit Point and Combat Rules, Version 4.0 are not the same rules as the Grim and Gritty: Revised and Simplified rules.

This is a very solid core of rules to make combat as nasty as you want to. The changes to hit points, armor class, and critical hits are all very useful in running a more serious, deadly game. The author's supposition that skill is more important in de [...]

This rough and harsh optional game mechanic well put together. The writer keeps making his point about realistic like combat. I understood the frst time. And if the reader doesn't get it by page 3. He's not going too. Thank to one mans obsession. We ha [...]

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
