Ironfire Ant

A type of spirit insect ranked 37th on the Exotic Insect Ranking. They are extremely tough, resistant to most spells and direct法宝 attacks (except high-tier water/ice spells). They can spew black flame and collectively transform into various shapes (spears, swords, etc.), acting like a mutable fire-attribute treasure. They require a harsh environment of molten rock and iron/copper ore to survive and cannot be tamed or bound by masters, as they will self-destruct.
