Critical Chance is the probability that an attack will be a critical hit. This can be raised with attributes, traits, skills, and weapons. Governing attribute is Precision. It can have a large effect on expected and actual DPS. The Boon Fury grants a flat 20% critical chance.
It is calculated for each hit and not each skill use. That is to say, in multi hit skills, each hit has a separate critical hit chance.
