Our convenient Monster Tile set can be used in place of, or in conjunction with, miniatures for gaming. Each tile is conveniently numbered to make it easy for the GM to keep track of which creature has taken what damage. No more goblin hoards made of six-sided dice!
Monster Tiles are lightweight, store in very little space, durable, and quick to set up. When you're done, just scoop them into a box or bag and you're ready to go. Perfect for convention gaming!
This set contains:
12x Medium Tiles
1x Collosal Tile
