Additional rules index

Throughout the Ars Magic product line, several additional mechanics have been added in supplements other than the core rulebook. Plenty of those books have included rules for specific situations, sometimes clarifying existing rules, sometimes expanding existing mechanincs or providing alternative mechanics, and sometimes providing rulesets for whole new activities.

This list is meant to provide a list of new or expanded mechanics found throughout the supplement books, along with book and page references. This page is meant to only be a list, not expanding on details about the rules referenced, instead linking to the proper page if one exists.
