A java based tool that takes load off the AD&D or OSRIC GM by being able to quickly load creatures encountered and manage the combat quickly without having to reference attack matrix, hd calculations or other charts and tables. With the press of a few buttons a GM can create an encounter and then cycle through the rounds of combat easily finding the AC the creature hit, damage done and other basic information.

Does NOT require a network connection to work and should run on just about any operating system or hardware.

Requires Java to run. You can get the latest version from here: http://java.com/en/download/index.jsp
