Alluria Publishing presents their solutions to 3d combat for both aerial and aquatic adventure. While developing their latest Pathfinder supplement, the Cerulean Seas Campaign Setting, they regularly reviewed common three dimensional solutions and devised a few of their own. If you already own Cerulean Seas, then you already have this material. If not, or you work with systems other than the Pathfinder Roleplaying Game, this will work with almost any system that uses miniatures and one inch squares as five-foot spaces (including most editions of Dungeons & Dragons). Product also contains plans and templates for stands that facilitate 3d miniature combat.
