Atom's Bulwark is a unique piece of armor in the Fallout 4 add-on . It is a legendary arm or chest piece of Marine armor.
It provides a
Damage Resistance and Energy Resistance of 15 at 0 Rads, equal to combat armor. They both increase linearly according to the following: every time the player character]s current radiation level increases past a 10% threshold of their total health, their total DR and ER will both increase by 5. Specifically, if 10% of their health bar is taken by radiation, they will gain 5 DR and ER. If 90% of their health bar is taken by radiation, they will gain 45 DR and ER.
The specific form of this item depends on the player character's level: below level 40, it spawns as either a left or right arm; above level 40, it spawns as a chest piece.
