GM Character Tool 4 is a character generator that assists users of the popular pen-and-paper roleplaying game Hârnmaster in creating, managing and storing characters.
It is almost identical with version 3, but is now provided by Columbia Games free of charge.
Hârnmaster is a fantasy game that emphasizes character development and combat realism using an unique interactive skill system.
GM Character Tool 4 supports Harnmaster 3 (HM3), the latest version of the Harnmaster rules from Columbia Games. Character Tool 4 may also be used in conjunction with Harnmaster Core (HMC), although some adaption needs to be done.
