The Pocket Edition contains core Chapters A-G, J, K, & W and the full Index. All errata is now incorporated, including the new Chapter A pages and revised Chapter F from Hollow Legions. The Pocket Edition also sports a handy IFT chart on the back cover.
The Pocket Edition is not meant to replace the full 2nd edition rulebook, but it is a comprehensive and handy table-side reference to the core rules that no devoted ASL player should be without.
