This hardy four-panel GM screen is completely customizable--just prepare the content you want on a piece of regular paper and slide it into one of the MATRIX's eight pockets. Throw your players a bone by stuffing the 4 outward-facing pockets with NPC portraits, maps, lore, and more. And then dig their graves by stuffing the inward-facing pockets with all sorts of nasty baddies, traps, and bosses. You can even add notes directly on the waterproof vinyl with the included dry erase marker. The Master's MATRIX also includes 4 double-sided art inserts and 4 reference pages for Dungeons & Dragons Fifth Edition and Pathfinder.
