Publisher's blurb: Rock Formations contains close to 400 boulders, stones, crystals, and stalagmites plus a number of rock clusters and rough stone walls, all laid out in a single PNG image with a transparent background. Customize your Dungeons in Blue creations by cutting and pasting individual components into your geomorphic maps. Note that a handful of boulders and stalagmites from this set have appeared in previous Dungeons in Blue products (notably Icon Packs One and Two), but there are still over 350 unique items in Rock Formations.
