Special Weapon Effects (Borderlands 2)

Important note on drops
Although all Legendary weapons can drop from any enemy or chest each Legendary has one specific boss or enemy that it is hundreds of times more likely to drop from. These specific enemies are what is listed after each non-quest reward weapon.

Pistols

 * Law: 100% Accuracy and recoil reduction while zoomed. +100% melee damage. (Quest Reward, "Won't get fooled again" or drop from the Sheriff in Lynchwood)

 * Fibber: Inaccurate stats displayed. Flavor stats +50% love, +3000% damage. Actual behavior is highly variable - may have enormously boosted critical hit damage, fire one projectile or several; shots may ricochet; if they do, ricochet hits may do substantially increased bonus damage; shots may also travel at slow speed when several are fired, if so 7 are fired for high damage - but will be constant for any given instance of the weapon. (Quest reward from Mal in Eridium Blight)
