D100 System Core

User summary: The D100 System Core presents a fairly straightforward mechanism for resolving actions in a tabletop role-playing game. The rules present a traditional, but minimal, Attribute-Class-Skill system. Resolution utilizes a d% roll that is modified. However, the modified result is compared to a simple action table and each digit signifies a particular result such as success or failure, degree of same, and hit location (for combat).
