Skill Conversions
The following outlines how skills and talents from ArM convert to d20 System skills. Italics indicate new d20 skills (stat in parenthesis indicates basis for skill) found in the New Skills section.
Mapped Skills
These skills have an equivalent in d20, and are thus mapped to that skill. In future editions of these conversion rules I may elaborate on changes to these d20 skills needed to accommodate ArM mechanics.
