| ||For legendary weapon effects in Fallout 4, see Legendary weapon effects.|
Legendary armor effects are effects applied to basic armor 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. Unlike unique armors, they are randomized and are never named. Legendary effects can provide the same effects as unique armor. Like unique armors, Legendary armors can be given a custom name and modified at an armor station.
Legendary armor pieces are only found on the bodies of "Legendary" variants of enemies and in the inventories of merchants. They can spawn at random locations throughout the Commonwealth, depending on the difficulty setting. They are much more difficult to defeat than regular enemies, as each one has a chance to "mutate" after their health is depleted, restoring it to full and boosting their stats. They will almost always have a legendary piece of equipment in their inventory.

S.P.E.C.I.A.L. armor effectsEdit
Fortifying, Cunning, Lucky and Sharp are stackable.
Almost Unbreakable, Nuka, Piezonucleic Lining, Quantum and Low Weight
Auto Stim armor effectsEdit
- The Auto Stim effect will not increase one's dehydration level in survival mode, unlike using a stimpak normally.
Camouflage armor effectsEdit
Cloaking and Chameleon effect has the same effect as the Stealth Boy mod for power armor - it turns the wearer invisible.
- Which part of the armor bears the mod is irrelevant; it will always work the same. All the underlying rules for effective sneaking still apply, so without good sneaking abilities (which means, enough points invested in the Sneak perk and enough U.S. Covert Operations Manuals collected) as well as careful use of the environment, even invisibility won't save the user from being detected by vigilant enemies. The mod also turns not only the wearer invisible but also their weapon including its sights (even the glowing portions of glow sights will fail to glow), making aiming quite difficult unless one of the electronic scope mods (night vision scope, recon scope) is installed. Furthermore, it works on companions as well, although the effect will simply stop working fairly often with no apparent reason and no reliable fix, somewhat limiting its usefulness (especially given most companions' unpredictable sneak behavior).
- Unequipping and re-equipping a chameleon piece from a companion's equipped inventory fixes their chameleon armor's effect.
Martyr's armor effectsEdit
- The Martyr's effect does not stack with additional pieces. In fact, wearing multiple pieces can prevent the slowing of time that the effect is supposed to cause. In the game's files, this effect was intended to only spawn on chest armor, however due to a bug it instead spawns on any armor piece. Also, if the player chracter has the superior Nerd Rage! perk, it will completely override the Martyr's effect.
Bolstering armor effectsEdit
- The Bolstering effect does not add extra resistance to the armor itself, but rather the player character. This can be apparent by looking at the resistance totals under the "STAT" tab of the Pip-Boy, or in the apparel section of the "INV" tab while having full HP, then again after taking damage. (The resistance of the armor does not change, but the totals do).
Damage Reduction armor and weapon effectsEdit
All Damage Reduction (i.e. Hunter's, Ghoul Slayer's, Assassin's, Exterminator's, Troubleshooter's, Mutant Slayer's, Cavalier's and Sentinel's) effect stacks with the armor and weapon effect of the same name.
- Equipping 7 pieces (weapon, helmet, left arm, left leg, right arm, right leg, chest) will negate all damage; except fire or poison damage. This causes enemies to panic and run away, due to how 'the AI of Fallout 4 is programmed.
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 (a semi-common glitch), legendary effects can be added to items using this alternative process:
- Drop the item on the ground.
- Pick up the item in the air by holding E(PC) (how you would normally drag ragdoll and other objects around).
- Open console and enter GetPlayerGrabbedRef. This returns the RefID of the item you're holding in the air.
- Take note of the returned RefID.
- Look up the ModID below for the desired legendary armor effect, note it as well.
- Enter the following in the console (substitute the appropriate RefID and ModID): [RefID].amod [ModID]
- For example, you would enter in something like this: f00726b.amod 001cc2ac.
- 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 circumstances can quickly turn into a chore.
- pc xboxone ps4 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. [verified]
- 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".
- pc xboxone 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.[verified]
- pc ps4 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. [verification overdue]
- pc xboxone 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. [verified]
- pc The Unyielding mode does not provide a +3 bonus to endurance. [verified]
