It's 1 Hit, 30 feet tall overall -- 12 feet for the Cone and 18 feet for the Flame -- and 10 feet in diameter at the base in 6P scale. It also counts as Cover without the Flame Piece if you want to add a Tile or something to round out the numbers. I think it's a good way to use up those Large Flame Pieces if you didn't have one already. For me, it's also the start to a new set of terrain. I also think it looks pretty spectacular and a bunch of these would make a good "Ooohh, look at that" display on a battlefield.
I currently have nine of these assembled. I hope this gives people ideas or techniques to use in their terrain builds. Flickr page.
