Lightning Claw

A lightning claw is a specialized type of power weapon, most commonly used in Space Marine Assault and Terminator squads. It consists of a powered gauntlet fitted with three or four blades, which can carve through armor and flesh with ease. Lightning claws are almost invariably worn as pairs.

Gameplay
In the Warhammer 40,000, the lightning claws count as a power weapon and enable the user to re-roll failed to wound rolls. If worn as a pair, they allow the user to make an additional attack.
