Foldout battle maps for your D&D campaign.
Dungeon Masters need awesome maps to create memorable encounters. This pack contains 3 full-color, double-sided, 21" x 30" battle maps with 1-inch scale grids. One map features two never-before-seen encounter locations: a besieged keep and a ruined, fortified manor. The other two battle maps are picked up from out-of-print products. You can even combine the maps in this map pack to create huge encounter areas. All the maps provide attractive, reusable terrain suitable for any D&D campaign.
Map Pack products are compatible with all editions of the Dungeons & Dragons Roleplaying Game and are designed for use with D&D miniatures.
