On the lowest level of the dungeon, flood water has created a stagnant mire that can impede the progress of adventurers and hide unusual threats. e-Adventure Tiles: Flooded Dungeons contains 25 tiles featuring water filled dungeon passages (10ft. and 20ft. wide) and chambers. In addition to the usual Bonus Tiles, this set features 10 more transitional tiles that will connect with any of the other Dungeon sets of e-Adventure Tiles.
