When a dragon's fireball lands near obsidian, it will turn into an obsidian diamond ore. This block is a combination of the properties of obsidian and diamond ore.
The chance for obsidian turning into diamond ore is configurable via gamerule, as well as what blocks can be converted via a block tag.
