Defender's harpoon gun

The Defender's harpoon gun is a unique weapon in the Fallout 4 add-on Far Harbor.

Characteristics
Although the Defender's Harpoon Gun does the same amount of damage as a box standard harpoon gun and has no default modifications, it comes with the "Penetrating" legendary weapon effect, meaning it negates 30% of a target's damage or energy resistance. As with the default harpoon gun, it can be modified to use different harpoons and have improved sights.
