AD&D Rules in Space (CSH)

__TOC__
As stated in the Concordance of Arcane Space, the bulk of the AD&D® game rules are unchanged by the move into space. However, the concepts of a spelljamming campaign do affect how those rules are applied. In addition to the rules changes listed in the Concordance, various other changes in focus or approach must be considered.
This section details the changes to the AD&D game rules when used in a SPELLJAMMER® setting environment. Most of these are changes in emphasis rather than changes in the rules themselves. Nevertheless, DMs (and players, once they have become familiar with the SPELLJAMMER setting) are encouraged to read through this section.
To make this section easier to understand and correlate to your AD&D 2nd Edition Player's Handbook and Dungeon Master's Guide, we have adopted the same organization. Each section below corresponds to a chapter in these books. (If a chapter required no additional material, it has been omitted from consideration here.)
