PFS StandardGang Up Feat 8*

Rogue 
Source Player Core pg. 172 2.0
Archetype Red Mantis Assassin
* This version of the Gang Up feat is intended for use with an Archetype and has a different level for access than the original feat.

You and your allies harry an opponent in concert. You can flank an enemy if it’s within reach of both of you and an ally—you and your ally don’t have to be on opposite sides. This benefits your allies as well as you, but only if they’re flanking with you, not each other. The other requirements for flanking must still be met.

Archetype Use

This feat can be used for one or more Archetypes in addition to the listed Classes. When selected this way, the feat is not considered to have its class traits.
