One is enough. – ~500% critical hit damage. Extremely high weapon zoom. Increased weapon accuracy and reload speed. Reduced base damage.
Usage & Description
The Monocle is a powerful critical hit weapon, but should only be used as a long-range weapon as its increased zoom can make it difficult to use in close-range combat and the reduced base damage makes it less effective with non-critical hits.
FL4K can make good use of this weapon for bursts of high damage with the Fade Away skill. Since every shot fired while it is active is a guaranteed critical hit, along with the Jakobs perk of a ricochet from a critical hit, this weapon can achieve massive single-shot damage in tight crowds of enemies.
