Sentry Ahab's helm

Sentry Ahab's helm is a unique robot mod for the sentry head in the Fallout 4 add-on Automatron.

Characteristics
Although Ahab's helm is classed as a mod, it essentially serves as a blueprint instead. This means that it can be crafted multiple times for different automatrons once it has been aquired. The most notable feature is the deathclaw skull joined with metal plates to form its shape.

Locations
Found on Ahab in the Fort Hagen hangar during the quest Headhunting.

Bugs
Attaching and reattaching Sentry Ahab's helm at a robot workbench gives 28 XP each time, and can be done unlimited times, which gives access to very easy XP. Every time the helm is attached, a new copy of it is made, it has a value of 68 Bottlecaps each, giving access to unlimited Bottlecaps. Creating this item cost no materials, so there is literally no limit for how much XP and Bottlecaps that can be generated with this bug.
