Dungeons & Dragons: 3.5e

In July 2003, a revised version of the 3rd edition D&D rules (termed v. 3.5) was released that incorporated numerous small rule changes, as well as expanding the Dungeon Master's Guide and Monster Manual. This revision was intentionally a small one focusing on addressing common complaints about certain aspects of gameplay, hence the "half edition" version number. The basic rules are fundamentally the same, only differing in balancing. Many monsters and items are compatible (or even unchanged) between those editions. New spells are added, and numerous changes are made to existing spells, while some spells are removed from the updated Player's Handbook. New feats are added and numerous changes are made to existing feats, while several skills are renamed or merged with other skills.
