Mod of Redemption/Dragon-Lead Chunk

"The caverns are heated with dragon bone..."

The Dragon-Lead Chunk is a post-skeletron ore that can be found in the cavern layer where the lava spawns at 1,500 feet (750 tiles) in a small world, 2,300 feet (1,150 tiles) in a medium world, and 3,350 feet (1,675 tiles) in a large world. It requires at least a Molten Pickaxe to mine.
