Every number in this card is at official 1× rates, with the fastest food. Taming speed and food consumption multipliers change all of it, and most servers are not on official — the calculator at the top of this tab takes your rates, a Sanguine Elixir, and every other food this creature will eat.
Effectiveness is what decides the bonus levels: every unit of food eaten costs a slice of it, so the food that needs the fewest units finishes at the highest level. That is why kibble is worth the trouble — not that it is much faster, but that it is fewer feedings.
Torpor drains at 0.3 per second while it is unconscious, so on a long tame you will need Narcotic to keep it down. The calculator works out how much.

- Dismounting Protection
All the Stegosaurus' plates effects protects the rider from being dismounted by almost any way (Except by
Net Projectile or if the Stegosaurus goes unconscious). This mechanic has different interactions with the Stun effect depending on the affected: If the Stego goes stunned the rider will not get dismounted and they can use weapons above the Stegosaurus, but they will not be able to control the Stego until the stun effect goes out. If the rider or both rider and Stego goes stunned the rider will not get dismounted, but player will not be able to do anything until the stun effect goes out. - Plates Damage Reduction
The Stego's plates reduces the incoming damage that it receives from projectiles by x0.7 its normal damage, however it receives x1.67 extra damage from projectiles that impact on the head. All its damage multipliers stacks with the Hardened Plates damage reduction. On ARK: Survival Ascended the body damage multipliers also apply for melee attacks.
- Weight Reduction
The Stegosaurus reduces the weight of the following resources by the listed amount while they are in its inventory:
