From publisher blurb: No time to whip up some aquatic-themed battle maps? No problem! Here's your solution! Includes 62 full concept battle maps--including a half-submerged, multi-level wizard's tower, sunken ruins, a beach side turtle humanoid village, a flooded temple, and a giant sand castle! All come with grid versions. But that's not all! 2 water overlays for tokens, medium and large sizes, so that your tokens can appear as if underwater! Goes well with the sets: Instant Dungeon Crawl: Undersea Adventures (1 & 2), Instant Dungeon Crawl: Flooded Dungeon and Instant Dungeon Crawl: Flooded Caves! Just add monsters!
