Skill Rules

Standard Skill Rolls

ArM makes use of standard skill difficulties. The following table converts these skill difficulties to d20 difficulty classes (DCs). [Note 9]

Task Difficulty	ArM Roll	d20 DC

Average	6	10
Difficult	9	15
Very Tough	12	25
Extremely Difficult	15	30

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.
