This special ability allows a weapon to find chinks in a foe's defenses using the wielder's knowledge of the target. Whenever the weapon's attack is a critical threat, the wielder gains a +2 bonus on the confirmation roll if she has 5 or more ranks in a Knowledge skill that is related to the target's creature type (such as Knowledge [planes] for an outsider opponent).
