Precision

 Precision is an offensive character attribute that increases the character's chance of a critical hit, which causes increased damage. In addition, there are a number of skill and trait effects that trigger on a critical hit. The amount of additional precision required to increase the chance of a critical hit by 1% is approximated by the following formula:

(0.0024 × Level2) + (0.06 × Level) + 1

At higher character levels, it takes an increased amount of precision to add 1% to the chance of hitting critically (since the formula depends on the square of one's level):

• 3.16 points at L20
• 7.24 points at L40
• 13.24 points at L60
• 21 points at L80 (the amount required seems to be rounded down from the 21.16 predicted by the formula).

At Level 80, the base precision is 916, with a crit chance of 4%, at 927 precision, it becomes 5%. At Level 80, Critical Chance and  Precision is found by the following formula:

Critical Chance = round down((precision - 822) / 21)

Base precision for a given level can be approximated by the following formula:

Base Precision = round(0.1 × Level2 + 3.162 × Level + 21.89)
