Understanding Damage in ARK
In ARK: Survival Evolved and Ascended, calculating your actual damage output involves more than just looking at your Melee Damage percentage. Every creature has a hidden Base Damage value. For example, a Rex has a base of 62, while a Carcharodontosaurus has a base of 211 (at zero stacks).
Key Factors in the Calculation:
Melee Stat: This is a multiplier of the base. 200% Melee means you deal 2x the base damage.
Mate Boost: Having a male and female of the same species nearby provides a passive 33% increase to damage and 33% resistance to incoming damage.
Imprint Bonus: If you are the person who raised the creature and it is 100% imprinted, you gain a 30% damage and resistance bonus while riding it.
Saddle Armor: This is the most significant damage mitigator. A primitive saddle (25 armor) reduces incoming damage by roughly 50%. A 100 armor saddle reduces it by 80%.
Example Scenario:
If you have a Rex with 400% Melee (Base 62):
Initial calculation: 62 * 4.0 = 248 damage.
With Mate Boost: 248 * 1.33 = 330.6 damage.
With 100% Imprint (Riding): 330.6 * 1.3 = 429.7 damage.
Hitting a target with a 25 Armor Saddle: 429.7 / 2 = 214.8 final damage.
