subtitle: Rules for Original Dungeons & Dragons Combat Using the Chainmail Rules
from the Introduction:
This pamphlet (formatted to neatly fit into an original D&D boxed set) is designed to hopefully clear some of the cobwebs by compiling the hints throughout the original brown booklets and spelling out the missing information. It presents a unique and potentially quite fun variant on combat in original DUNGEONS & DRAGONS, and one the author hopes will provide enjoyment in actual play as well as one potential answer to this philosophical debate.
Note: to use this pamphlet you will need BOTH the original DUNGEONS & DRAGONS booklets AND the original CHAINMAIL rules. It does not reproduce rules from either source; it merely serves as a bridge to link the two, cross-referencing rules from D&D with those from CHAINMAIL.
