The Rock Elemental must be trapped in a sturdy stone or metal enclosure and carefully knocked out with cannon fire aimed at its head, then fed suitable food while protected during taming. As a mount, it offers exceptional durability, resistance to most attacks, elemental immunity, powerful ranged attacks, high carrying capacity, camouflage, and strong base-defense utility. When encountered, its rocky disguise can make it difficult to spot, so confirm suspicious formations with a spyglass and retreat if it becomes aggressive. Defeating one generally requires powerful creatures, bleed attacks, explosives, or heavy weaponry rather than fighting it on foot.
