No one doubts the power of the gods! Deities of healing, fiendish lords of destruction, spirits of the land, and entities from beyond the stars all receive reverence in their own sanctums and sacred sites. Whether your heroes need healing or are thwarting an enemy cult, no Game Master wants to spend time drawing idols and altars. Fortunately, with Paizo Publishing’s latest GameMastery Map Pack, you don’t have to! This line of gaming accessories provides simple and elegant tools for the busy Game Master.
Inside, you’ll find 18 captivating 5" × 8" map tiles that can be combined into a variety of serene sanctuaries and sinister shrines, including:
Altar to the Old Gods
Game Masters shouldn’t waste their time sketching maps every time their players need to pick up supplies. With GameMastery Map Pack: Shrines, you’ll always be ready whenever adventurers need to make (or become) offerings to the gods!
Wet, dry, and permanent markers erase from the tiles!
