Stone-encrusted biter variants hardened by underground minerals. Ironhide Biters are heavily armored tanks — 40% more health, 60% physical resistance, and a stone-like resilience that makes them extremely difficult to take down, though they move 15% slower. Includes 4 biter sizes, 4 spitter sizes, 4 worm sizes, and 2 spawner types. Required by the Mineshafts mod.
