Attack Power or Raw Damage is a damage statistic in Monster Hunter World (MHW). Monsters also have raw damage, which is offset by the hunter's Defense stat.
How Attack Power is Calculated
Formula for Physical Damage displayed
Raw Base x Sharpness x Combo Move x
x Monster Part x Quest Difficulty x Rage Status
For example, hitting a Great Jagras' tail with a Wide Slash from the Buster Sword III, assuming Quest Difficulty and Rage status multipliers of 1.0 and no boost to Attack from Items or Skills, will yield:
149 (Raw Base)
x 1.2 (Sharpness multiplier for blue-level sharpness - non-elemental)
x 0.26 (Combo Move multiplier for Great Sword's Wide Slash attack)
x 0.45 (Monster Part multiplier for Great Jagras' tail against Cut Damage)
= 21 damage
Raw Base or True Raw
The Attack value displayed on the Attack Status portion of the Equipment Info screen is obtained by multiplying a weapon's Raw Base by a modifier specific to the weapon's type. Changes to Attack made by Skills such as Attack Boost or Items such as Demondrug are also subjected to this multiplier. The weapon type modifiers are as follows:
Hammer (x 5.2)
Great Sword (x 4.8)
Hunting Horn (x 4.2)
Charge Blade (x 3.6)
Switch Axe (x 3.5)
Long Sword (x 3.3)
Insect Glaive (x 3.1)
Lance (x 2.3)
Gunlance (x 2.3)
Heavy Bowgun (x 1.5)
Sword and Shield (x 1.4)
Dual Blades (x 1.4)
Light Bowgun (x 1.3)
Bow (x 1.2)
To calculate a weapon's Raw Base, simply divide its displayed Attack value (without boosts from Skills or Items) by its type-specific modifier.
While trying out weapons in the Training area, note that the Monster Part multiplier for the large training post is 0.8 for Physical damage and 0.3 for Elemental.
Refer to Affinity to see how it can affect displayed damage numbers.
Remember that Raw Damage is subdivided into three types: Cut, Blunt, and Ammo, and that Monster Body Parts have individual Body Part Multipliers for each.
Refer to Damage Types to see how different weapons my perform in combat.
