Activation rate is far higher for monsters with a Double Attack trait, estimated at around 25%.
Effect Overview[]
Double Attack effects from gear, food or buffs may activate without native access to the job trait.
"Double Attack"+1, "Double Attack"+1% or Enhances "Double Attack" effect are all different wordings of the same effect and will stack.
Additional attacks produced by Triple Attack, and to a degree, Occasionally Attacks X Times weapons are not affected by Double Attack, and only one of these effects can proc at once.
Example: Joyeuse will never attack more than 2 times, and the 2nd attack will never be subject to Double Attack. Furthermore, Kraken Club is never affected by Double Attack if its "Attacks 2 to 8 Times" effect proc's, though it will increase the amount of hits per round.
Double Attack can trigger on both weapons when Dual Wielding, both hands when using H2H weapons and both attacks on virtue stone weapons.
Example: Faith Baghnakhs can produce an additional attack on both hands (consuming 2 virtue stones), and each of these 4 attacks are subject to Double Attack.
When using a normal H2H weapon, the double attack will only appear on the screen on the left hand. When both fists trigger a Double Attack, both are done with the left hand on the screen. When using Faith Baghnakhs, double attack from extra swings can appear on left and right hands.
On multi-hit weapon skills, Double Attack can proc on any hit of the weapon skill. Note, however, that Double Attack cannot proc to induce a weapon skill to attempt to hit more than 8 times.
TP return for weapon skills will increase by 1 TP every time double attack activates during the weapon skills.
