What to buy?

[Olaf the Stout]

Dungeon Tiles are printed on thick cardstock. Some people have used dry-erase markers on them without a problem but I would say do this at your own risk. They make life a lot easier since you don't have to draw the map as you go, you can just plunk down the next dungeon tile. They also look a lot nicer.

Here are the links to them on the WotC site:

D&D Dungeon Tiles
D&D Dungeon Tiles II: Arcane Corridors
D&D Dungeon Tiles III: Hidden Crypts
D&D Dungeon Tiles IV: Ruins of the Wild
D&D Dungeon Tiles V: Lost Caverns of the Underdark
