If you use miniatures for your roleplaying games, I’m sure by now you’ve at least seen those hex and square grid battlemats. Y’know, the one’s you can roll up but require water-soluble markers. Longtooth Studios offers an alternative in the form of white, rigid, dry-erase boards scored with 1 inch grids. Their Battle Graph Boards are also modular, connecting to each other like puzzle pieces, and thus allowing you to add to the table only what’s needed for the encounter.
