Subject and Contents[edit]

This was a revised edition of the core rules that streamlined gameplay a bit. The layout was improved from First Edition but still rudimentary by modern (c. 2012) standards.

Contributions to Canon[edit]

ArM2 introduced the Houses of Hermes, though it mentioned them only briefly and left the details to the supplement, Order of Hermes.

Comparison with Other Editions[edit]

Compared to ArM1, Second Edition was generally more polished and streamlined. Many of the changes seem to have been made with playability in mind:

  • ArM2 was the first edition to use seasons for laboratory work and character advancement (ArM1 used months, which were comparatively much more cumbersome)
  • ArM2 converted Parma Magica into an Ability (in ArM1, Parma Magica was a Rego Vim General spell)
  • Combat was revised to be somewhat simpler and faster-paced.


ArM2 was out of print for many years. On December 2, 2016, Atlas Games announced on Google+ that a PDF was finally made available.

Opinion & Reviews[edit]

ArM2 maintained a loyal following even after ArM3 was published, and was long called the One True Edition (or OTE) by its proponents.
