The アンキロサウルス, a tamable, herbivore creature in ARK: Survival Ascended, is a common sight across multiple maps. It falls within the Farmer classification.
With 700 base Health, the アンキロサウルス is solidly tanky. Dealing 100% base Melee Damage, the アンキロサウルス brings solid damage output to the table. Stamina sits at 175 base, providing average stamina. It carries 250 base Weight - a solid weight pool.
Taming the アンキロサウルス requires rendering it unconscious first - use Tranq Arrows, Darts, or Shocking Tranq Darts to apply torpor. Feed it Regular Kibble for the fastest tame and highest effectiveness bonus.
Once tamed, the アンキロサウルス is valued for its harvesting efficiency, collecting key resources faster than most tools. It reproduces by laying eggs, which must be incubated between 16°C and 20°C. Killing a wild アンキロサウルス yields 6 base XP. It can be cloned at a Cloning Chamber for 0.93 Element plus 0.01 Element per level.
