Atom's Bulwark

Atom's Bulwark is a unique chest piece in the Fallout 4 add-on Far Harbor.

Characteristics
This unique marine armor chest has the effect of raising one's damage and energy resistance the more radiation one accumulates. These resistances are 40 by default, but grow by 5 with every 100 rads accumulated.

Location

 * Received from the synthetic High Confessor Tektus after the completing of Reformation.

Behind the scenes
Another version of Atom's Bulwark was cut from the add-on before release. Marked as obsolete, its enchantment would have provided an increasing energy resistance bonus as the player character gained rads. It would cap out at 60 Energy Resistance, with over 900 rads in the player character's system.
