“The B/X Companion is a re-imagining of what could have been, had the 1981 editions of the Original Fantasy Role-Playing Game (the Basic and Expert sets edited by Tom Moldvay, Dave Cook, and Steven Marsh) been followed up by a third Companion volume promised in their pages. Using the same format as the original volumes, and working from the hints and info provided in those 1981 editions, the B/X Companion provides rules for high level play, including levels 15th through 36th, 60+ new spells, 100+ new magic items, 80+ new monsters, rules for running dominions, mass combat & siege warfare, astral travel, and more…all in 64 pages.”
