Arms Law, 1st Edition was the first Rolemaster product released by Iron Crown Enterprises when it was published in 1980. Arms Law is the core rules weapons system for Iron Crown's original Rolemaster fantasy role-playing system. This First Edition book was later combined with the natural animal and martial art attack charts from the book "Claw Law" as the Second Edition book "Arms Law & Claw Law". Arms Law covers weapon attacks and includes a 12 to 24 page book and several pages of separate detailed attack charts for 30 weapons and statistics for various critical strikes and fumbles. Note: Internet sources state the first printing had a blue-and-white illustrated cover, single-sided attack charts, and 24 pages of text. Later versions had a black-and-white illustrated cover and were printed in a smaller font, reducing the number of pages to 12.
