Polymancer was a magazine covering roleplaying games and related hobbies such as miniatures, wargaming, and LARPs.

Articles in Polymancer tended to be long (over four pages) and the black and white illustrations differed from the color artwork found in Dragon.

[5] The articles in Polymancer were eclectic but they appeared under a few regular headings: There was a full adventure scenario in every issue.

During its run, Polymancer had horror, fantasy, post-apocalyptic, science fiction, pulp, cyberpunk, and Espionage scenarios.

One scenario was written to be played as a set of linked miniatures wargame battles, as an RPG adventure, or both.

Each of these game rules systems were implemented in Polymancer magazine in order to allow the content to contain usable game stats, while maintaining the publication's policy of being easily convertible to rules systems that the magazine's readers would prefer to use themselves.

[12] It was stressed that Polymancer Studios did not intend to create another generic RPG as a product, but rather as a tool to make the magazine more relevant.

Although based on percentile dice, Mojo differed from other percentile-based games such as Call of Cthulhu and Rolemaster.

Basic task resolution was accomplished by rolling under the character's attribute + relevant skill + a modifier set by the gamemaster on an ad hoc basis.
