Hmmm. probably could be used for dancing lights (if you had enough of them), wall torches, will-o'-wisps (other colors), tiny fire elementals, fire shield, flame blade bearer, flaming sphere indicator, light spell effect. Only three?
This looks like it will compatible with the Waterfront Map Pack. What's going to be on the flip side? Is there any chance to get the Map packs to have there own flipsides? Having just a white side seems to be a waste of a side.
