Acrocanthosaurus
DMG · 21 maps
Overview
The Acrocanthosaurus is a large carnivore with a unique taming mechanic involving narcotic feeding during its frustrated roar. It excels in combat and structure damage, making it a powerful offensive mount. The Acrocanthosaurus can be airlifted by Quetzal or Karkinos for fast deployment.
It is primarily used for raiding and taking down enemy structures due to its high melee damage and ability to damage Stone, Wood, and Thatch structures.

The Acrocanthosaurus must be tamed via knockout, but it is immune to ranged tranquilizers. You must hand-feed it Narcotic, Bio Toxin, or Ascerbic Mushroom during its frustrated roar. Use a Fabricated Sniper Rifle to trigger its shield stance and track adrenaline phases. Immobilize it first with a Chain Bola, Bear Trap, or Large Bear Trap.
The best food is Exceptional Kibble, which requires about 17 units. The tame takes around 58 minutes and needs 96 narcotics. Use the calculator below for your settings.
