The Amargasaurus is tamed by matching its temperature with insulating soup, allowing it to pursue carnivores, helping defeat its target without harming it, and feeding it kibble or berries when hungry; a trap can improve safety. Once tamed, it serves as a versatile war mount with powerful close-range attacks, elemental spikes, and temperature adaptation that aids survival in harsh environments. When encountered, keep your distance from this fast, aggressive creature, whose tail strikes and elemental attacks can overwhelm survivors, creatures, and even damage saddles.
