Menacing: This ability can only be placed on a melee weapon. This weapon property helps allies deal with flanked foes. When the wielder is adjacent to a creature that is being flanked by an ally, the flanking bonus on attack rolls for all flanking allies increases by +2. This ability works even if the wielder is not one of the characters flanking the creature.

Aura Moderate illusion; CL 10th; Craft Magic Arms and Armor, phantasmal killer; Price +1 bonus.
