The Sham

The Sham is a Absorb Shield manufactured by Vladof.

Special Shield Effects
Extremely high bullet absorption chance. Greatly reduced shield capacity, reduced recharge delay and recharge rate.

Usage & Description
The Sham is heavily geared towards being used against any enemies that use firearms, relying heavily on its absorption rate to prevent bodily harm to the user. All Vladof shields come with a chance to absorb bullets, but what makes The Sham special is its dramatically high chance of ammo absorption compared to any other shield in the game (see Absorb Chance).

The Sham's Achilles heel is not only its low capacity but the fact that there are enemies in Borderlands 2 who do not need to use guns to deal damage, thus making The Sham's viability in combat dependent on what the user is in combat with at the time.

Absorb Chance
The lowest possible absorb chance on The Sham is 76% (if Body, Battery and Capacitor parts of the shield are of Dahl manufacture, which reduces special effects on shields) and the highest possible absorb chance is 94% provided the Body and Battery are manufactured by Maliwan, and the Capacitor by Hyperion, at the cost of less shield defence and recharge rate.

This doubles absorb chance on the other Legendary Vladof shield in the game, the Transformer, which has a highest possible absorb chance of 42%, and any other purple rarity Vladof shield which have highest absorb chances of 48%. Please notice that both of that values can be as low as 19% and 15% respectively, and even lower on white, green or blue shields, which could make The Sham to have up to 9 times the absorb chance of an average shield.

Trivia

 * The name of the shield is a reference to the ShamWow commercial. The red text is a reference to ShamWow pitchman Vince Offer's pitch catchphrase "...Because you know we can't do this all day..."

It is also a reference to the Tediore Defender, from the original game.
