Ores

Ores are common items found in BTD6. They are usually dropped by bloons made of metal, rock, or crystal. They have a 20% chance of being dropped. Ores can be crafted into a large number of different rock or metal based items, but sometimes an ore may crack open during crafting and reveal a much more valuable and rarer item ranging from iron to diamond. Ores may also be sold for significant profits that may range from $50 to $1000.
