With Rules of Wor, Three Sages brings out an OGL supplement for fantasy d20. “Plug and Play” style combat rules change the game from turn-based to judging concurrent actions with a strike rank system. The second section adds two new races and six new classes including an innovative holy fighter and holy servant character class. Other campaign-enhancing materials include the Panacean spell school, cult descriptions, and a fun character background generator to fill out family, friends, and rivals.

This product is a supplement for the Dungeons & Dragons core rulebooks. It is published under the Open Gaming License (OGL) and is compatible with the D&D 3.0/3.5 edition rules and the D20 System.
