Your highness, we have evaluated the technology encountered in Berlin which was employed by the Black Widow. Our findings conclude effects and recovery time are quite similar if not identical to a standard issue law enforcement stun gun. Variations in the weapon’s impact and effectiveness are completely reliant upon the operator’s settings. We estimate that Romanoff’s devices are capable of emitting at maximum 250,000 to 300,000 volts at 4 to 5 milliamps, and at minimum 40,000 to 50,000 volts on a barely measurable amperage.
Based upon King T’Challa’s experience, the minimum settings were engaged. With delivery of a small amperage current, the effects should only be temporary. With the added protection of his armor, he was spared some of the more uncomfortable side-effects such as weakened or sore muscles, cramping, external first-degree epidermal burns, temporary nerve damage, and temporary lapses in consciousness. As with any device that incapacitates the victim, there is also risk of blunt force trauma injuries from a fall. Recovery time from this attack is minimal.
Should the highest setting of the devices be engaged and a prolonged exposure to high amperage current is experienced, side-effects could include permanent nerve damage, third-degree subdermal burns, loss of vision, even death. Needless to say, recovery time from an attack of this magnitude could take weeks if not be enduring and indefinite injuries.
