Chalicotheriums are passively tamed by sneaking behind them and feeding them beer when hungry, retreating between feedings to avoid aggression or resetting progress; ghillie armor and traps can help. They are versatile mounts and formidable cave fighters, using wide knockback swipes, ranged boulder attacks, rider weapons, and efficient resource gathering, while sitting allows rapid health regeneration. When encountering one, keep your distance and isolate it from others, using ranged attacks from safety or a strong mount while avoiding its slowing, disorienting projectiles; inexperienced survivors should avoid fighting them.
