View source for Implement (Quality)

A weapon with this quality counts as a magic implement, for any wielder that has an Implement Bonus as a class feature.  This means that, while wielding this weapon, the wielder can add their implement bonus to any to-hit rolls (including melee touch, ranged touch, standard melee, and standard ranged to-hits) that are required by a spell or spell-like ability.  The implement bonus does NOT apply to to-hit rolls for normal attacks (such as an attack with the weapon, or an attack of opportunity with the weapon), but only when making a to-hit roll for a spell or spell-like ability.  In addition, a weapon with the implement quality can be flicked and swished around in order to perform the somatic component of any spell the wielder is casting, in lieu of having a hand free to do so.
