Iron Fire Ant
Origin
Natural spirit insect. Requires extremely hot lava environments with abundant iron/copper ore to survive. Nearly extinct.
Effects & Usage
Extremely tough defense, nearly immune to physical attacks and most spells. Weak to mid/high-tier water and ice spells. Can spew black demonic flames. Can merge together to transform into various weapon shapes (spear, sword, arrow) for powerful attacks. Cannot be tamed or bound by masters – they self-destruct if forced.
