Pearl Harbor Tool Box

Origin
Pearl Harbor is an American naval base stationed in Hawaii. During World War Two it acted as the launching point for battleships into the Pacific. To cripple their forces, the Japanese Navy launched a surprise attack to keep the United States out of the war. Over 300 planes were launched, destroying 188 American aircraft, killing 2403 Americans and wounding another 1178. Structural damage to military instillations was minimal, as were losses the Japanese suffered. The strike shocked the American public and the nation declared war on Japan the very next day, entering World War Two on the Allied side.

Effects
Vehicles and devices that are damaged will be instantly repaired when it contacts any tool. The one exception is boats and watercraft, which are only temporarily strengthened. The existing damage will return and worsen, causing the craft to sink.
