Gang Up (Feat)
You are adept at using greater numbers against foes.
Prerequisites: Level 6, Combat Expertise
Unlocks: Team Up (Feat)
Benefit: You are considered to be flanking an opponent if at least two of your allies (not including yourself) are threatening that opponent, regardless of your actual positioning. This feat allows ranged attackers to potentially gain all of the benefits of flanking an enemy, and it also allows melee attackers to potentially gain flanks when out of normal flanking position.
Normal: You and an ally must be positioned on opposite sides of an enemy creature to flank it.
