Double strike

Double Strike is an auto-attack proc that is unique to Daggers. Double Strike hits the target twice with one attack, and the damage for both strikes are calculated separately. Having 100% chance to Double Strike would double your effective attack speed with daggers from 1.33 to 0.67 seconds per hit.

The chance of executing a Double Strike depends on your rank in Dagger Mastery. With 0 Dagger Mastery, your base chance of executing a double strike is 0% even while wielding daggers. Note that some skills like Assassin's elite skill Locust's Fury can alter the chance.

Dual Attacks that successfully hit always result in double strikes, although the second hit can still be blocked or evaded since each is calculated seperately.
