Fallout 4 legendary armor (2024)

	For legendary weapon effects in Fallout 4, see Fallout 4 legendary weapons. For legendary effects in Fallout 76, see Fallout 76 Legendary Mods.

Legendary armor effects are applied to basic armor in Fallout 4, that use special prefix modifiers that cannot be obtained elsewhere. They cannot be scrapped, but can be modified. They will appear on screen when picked up, and are marked with a star. Legendary armor pieces can also be awarded for completing certain quests and can rarely be found in tribute chests.

¹ The legendary effect mod_Custom_PA_APRegenRad adds an enchantment ench_mod_LegendaryPA_RadsCoreHealth, which increases the power armor's fusion core drain by 50% and adds a perk LegendaryPA_RadsCoreHealth, that does not have any effect because its condition can not be fulfilled. Additionally, the legendary effect also increases damage resistance and energy resistance by 2.

Console command

Legendary effects can be added to items by dropping them on the ground and using the console command attachmod while having them selected, followed by the mod ID. You can't stack several mods on a single item, but you can stack over multiple pieces (armor). You can also replace a mod with another one via console. If the item is for some reason unclickable, legendary effects can be added to items using this alternative process:

1. Drop the item on the ground.
2. Pick up the item in the air by holding E_(PC) (how you would normally drag ragdoll and other objects around).
3. Open console and enter GetPlayerGrabbedRef. This returns the RefID of the item you're holding in the air.
4. Take note of the returned RefID.
5. Look up the ModID below for the desired legendary armor effect, note it as well.
6. Enter the following in the console (substitute the appropriate RefID and ModID): [RefID].amod [ModID]
7. For example, you would enter in something like this: f00726b.amod 001cc2ac.
8. The item will drop to the ground, and when you go to pick it up, you will get an overview similar to the one you get when you pick up any given legendary item for the first time.

By utilizing the steps described above, it is possible to apply legendary effects to power armor pieces. Keep in mind, though, that contrary to regular armor and weapons, power armor can't be renamed, so keeping enhanced power armor pieces apart from others of the same name under these circ*mstances can quickly turn into a chore.

Bugs

• When using armor with the Chameleon modifier, the Pip-Boy's display will be warped and the text colors over bright and blurry, making it difficult to read. If crouching and invisible, attempting to access the Pip-Boy will sometimes result in the UI being rendered partially or completely white and unusable. If standing and invisible, attempting to access the PipBoy can result in the PipBoy being transparent so the user is left looking through the character's arm.
  • Can be solved by saving and then loading that save or going into 3rd person and back into 1st person. Another way to solve this is to be using the Fallout 4 Pip-Boy companion app on a mobile device, such as a smartphone or tablet.
  • The over-bright, blurry Pip-boy effect seems to be the game adding the HUD and Pip-boy lighting/color together, so if you change one or the other in the Settings so that these colors contrast (i.e. red Pip-boy and green HUD), the Pip-boy becomes more readable, though still not as clear as when not "invisible".
  • Each additional piece of chameleon armor equipped appears to slightly reduce the distortion of the Pip-boy display.
• There is a relatively uncommon bug whereas the player character will retain the effects of chameleon permanently, even after removing all buffed items. Suicide seems to fix this bug.
• The Martyr mod may not work at certain times unless you go into V.A.T.S. This seems to be related to having multiple items equipped at once with the Martyr effect.
• The Fortifying mod will add 10 carrying weight but no HP bonus. It does show you had +1 Endurance on S.P.E.C.I.A.L. chart. This might be an intended design, in case player buff too much HP with all armor pieces equipped in higher level.
• The Unyielding mod does not provide a +3 bonus to endurance.
