Long Walls Expansion - Mini Dungeon Castle Cavern DND Terrain for Tabletop RPGs, Dungeons & Dragons, Pathfinder, War Gaming, and More! by DCD (10pcs, adds 5ft of Walls)

These are just the job for my D&D games, I have their dungeon as well and recommend them for a cheap way to give a visual representation of you Dungeon

Dirt cheap Dungeons and Loke Battlemats a winning team.

Love these modular dungeon walls. Also highly recommend this long-wall expansion, it can definitely give your dungeon much more space without having to sacrifice important smaller wall segments. An absolute must if you already have one set but sometimes find yourself just shy of the dungeon you want in terms of space before resorting to markers making up the difference.
