Hit

Hit refers to physical damage that occurs as a result of an attack made with melee or ranged weapons. The chance to hit increases by 1% per 15.8 hit rating points at level 70 and 10 hit rating points at level 60.

The base chance to miss with maximum weapon skill against an opponent of equal level is 5% for two handed and 24% for dual wield. The base chance to miss with maximum weapon skill against an opponent three levels higher is 9% for two handed and 28% for dual wield.

Hit rating decreases chance to miss rather than increases chance to hit. Base chance to miss a raid boss (level 73 and 365 defense) with maximum weapon skill (350 at level 70) is 9% for two handed and 28% for dual wielding. Chance to miss increases by 0.1% for each point of difference (equal to or lower than 10) between attacker weapon skill and mob defense.

Melee attacks divide in to two categories: auto attacks (white) and special attacks (yellow). Auto attacks use a one roll table and special attacks use a two roll table. Base chance to miss is the same for both auto attacks and special attacks. Attacking a mob from behind removes parry and block from both tables, provided the attack is more than 0.5 yards away.

Auto Attacks (One Roll Table)

Each melee auto attack made by characters against mobs will result in one of the following in order of precedence:

Result
Miss
Dodge
Parry
Glancing blow
Block
Critical strike
Hit

Increased hit rating can result in increased critical strike results from auto attacks. For example: maximum dual wielding weapon skill, chance to hit 0% and chance to critical strike 50%. Dual wield auto attacking a raid boss from behind results in a loss of 8.6% critical strike:

Result	Chance
Miss	28%
Dodge	5.6%
Glancing blow	25%
Critical strike	41.4%
Hit	0%

Increase chance to hit to 10% and decrease chance to critical strike to 45% results in no loss of critical strike:

Result	Chance
Miss	18%
Dodge	5.6%
Glancing blow	25%
Critical strike	45%
Hit	6.4%

Special Attacks (Two Roll Table)

Each melee special attack made by characters against mobs will result in one of the following in order of precedence:

Result
Miss
Dodge
Parry
Block
Hit

If the result is block or hit, then a second roll occurs to determine critical strike as follows:

Block: roll for blocked hit or blocked critical strike
Hit: roll for hit or critical strike

Increased hit rating can result in increased critical strike results from special attacks upon exceeding the base 9% chance to miss. For example: maximum weapon skill (350 at level 70), chance to hit 0% and chance to critical strike 25%. Special attacking a raid boss (level 73 and 365 defense) from behind results 21.35% critical strike (25% of 85.4%). Increase chance to hit to 10% results in 23.6% critical strike (25% of 94.4%).
