on running a campaign and planning adventures for characters of level 15 and higher. The introduction also constructs a feudal system to provide a basis for the dominions, which will be granted to or conquered by the player characters. This section ends with notes on the organization and running of tournaments. The next section "The War Machine" was designed by Douglas Niles and Gary Spiegel as a method for coping with large-scale battles, especially those in the campaign's background. This book covers running high-level campaigns, including mass combat, other worlds and planes, and new monsters and treasure. It also contains three mini-scenarios. Reception The Companion Set was reviewed by Megan C. Robertson in issue 61 of White Dwarf magazine (January 1985), rating it a 7 out of 10 overall. Robertson noted that most characters that reach 15th level in the Basic D&D game should be thinking of settling down and retiring and felt that the D&D Companion Set'' provides: "some ideas for this to be a little more interesting than simple retirement".
