Hit Rate

Hit Rate is determined by comparing target evasion with player accuracy or ranged accuracy. It also suffers some level correction, as well, but the general formula is:

Hit Rate (%) = 75 + floor( (Accuracy - Evasion)÷2 ) - 2×(dLVL)

dLVL = Attacked Monster's Level - Attacking Player's Level

The dLVL term only applies in areas with level correction.

Increasing Hit Rate is often the single easiest way to improve your melee damage, but it has a maximum:

• 99% For all pets.
• 99% For both fists of Hand-to-Hand.
• 99% For one-handed main-hand weapons.
• 95% For one-handed secondary off-handed weapons.
• 95% for two-handed weapons.
• 95% for ranged attacks.

• Under the effects of Sharpshot the maximum hit rate becomes 99% for ranged attacks.

This means that (no matter how much accuracy you stack), the maximum Hit Rate that you can hope to achieve in the long term has a capped %.

Additionally, for melee attacks, hit rate cannot fall below 20%, no matter how low your accuracy is or how high the target's evasion is.
