The X-Acrocanthosaurus is a large carnivorous variant of the Acrocanthosaurus. It gains a significant boost to melee damage and speed when under the effect of Adrenaline, triggered by its special abilities. This makes it a powerful offensive mount in combat scenarios, especially when maintaining aggression through its roars and stomp attacks.
It can be airlifted by Quetzal or Karkinos for fast deployment.

Taming the X-Acrocanthosaurus requires a knockout method. Use a Chain Bola or trap it with a Bear Trap, Large Bear Trap, or Plant Species Y to immobilize it. Then sedate it using weapons such as the Bow, Crossbow, or Fabricated Sniper Rifle with Tranq Arrow, or a Longneck Rifle with Tranquilizer Dart.
The best food is Exceptional Kibble, with Raw Mutton also working well. Approximately 17 units of Exceptional Kibble are needed. The tame takes about 58 minutes and requires 96 Narcotics. Use the calculator below for your settings.

Each harvest event rolls resources independently. Actual yields vary.
Killing the X-Acrocanthosaurus yields Acro Adrenal Gland, Hide, Raw Meat, and Raw Prime Meat. The Hatchet yields the most Hide, while the Pick maximizes Raw Meat. Dinos with Prime harvest capabilities are best for Raw Prime Meat.
The X-Acrocanthosaurus does not function as a gatherer while ridden. None of its attacks harvest resources from structures or nodes. It is designed purely for combat utility and mobility, not resource collection.

The X-Acrocanthosaurus has a +400% weakness to spike walls, making them extremely effective in defense. It also takes +120% damage from instant damage sources like explosives or raid mechanics. Conversely, it is highly resistant to mining drill harvest damage, reducing it by 100%. Avoid using melee attacks with impact effects, as they are only half as effective.
The head has a 1.5× damage multiplier, making headshots more effective for faster knockout or combat damage. Aim for the head when using ranged weapons or engaging in melee.
