WarLock Tiles: Dungeon Tiles 1
WarLock Tiles: Dungeon Tiles 1 - Rules of Play says:
The WarLock Dungeon Tile system solves many of the problems present with other tile systems. The WarLock clips allow players to construct rooms in advance and place them on the table as needed. 1 inch tall walls make it easier for players to move pieces around the in the room as they play. Offset walls provide you with the ability to place figures in any square on the grid, without pesky corners eating into your play area. Additionally, all tiles are reversible with wood design on one side and stone on the other for double the functionality. Also included are adapter clips for two of the most popular clip-based tile systems, DragonLock and OpenLock, to help other players integrate these tiles into their collection.
