Volley Fire 1 (Source)

Q. How does Volley Fire work?

A. It takes one default attack from allranged persons toward one target of your choosing. They will then return to their target of choice, If it succeeds, that is. What you do is, during the volley fire, you deselect your target. That selects the Volley fire target. Then the Squad Commences firing on the selected target. Most Squads never even know that the skill is working, because it doesn’t re-target the SL’s target, it just auto-shoots the target. Volley Fire is untargetted and will hit the three pools at a 3:2:1 ratio Volley fire can be used in PVE to draw aggro off of yourself. To clarify and reitterate, group members do NOT change ttargets during this process, they simply fire at the SL's target when the SL's queued volley round comes up then go back to attacking their original targets. When no one is engaged, and you use /volleyfire.... Nothing happens. Nada, Zilch, nothing. Your party must be engaged in combat before using /volleyfire.

Volley fire only works with RANGED weapons.
