Power Armor Frame

The power armor frame is the basis for all power armor in Fallout 4.

Characteristics
Any combination of power armor parts can be equipped on a power armor frame', which is a furniture object that does not exist in your inventory. A power armor station can be used to modify power armor components on a frame.

The base frame provides 60 Damage Resistance, and Energy Resistance, but negates effects of other apparel and armor worn underneath. It also sets the base Strength to 11, which can result in negative effects to carrying capacity. Although the weight of worn apparel and armor is not ignored, any power armor plate segments attached to the frame do not affect carrying capacity.

Power armor requires a fusion core to function and the fusion core's power drains over time. Actions that consume AP deplete additional power. Once the fusion core is drained (or if there is no core installed in the armor at all), the Sole Survivor will still be able to slowly walk in the armor, but will be over-encumbered and unable to use V.A.T.S. Power armor negates falling damage, but will itself be damaged if falling from a sufficient height, as well as damaging others near the point of impact.

Comparison to previous portrayals
Power armor in Fallout 4 requires no training to use as it did in Fallout 3 and New Vegas and is unique in other aspects as well. First is the frame upon which separate armor segments are mounted, as compared to previous suits which existed as holistic entities which were worn whole aside from the helmet. Second, the player character interacts with the frame in the world to use the power armor, instead of equipping the power armor via the inventory. The use of fusion cores as 'fuel' for power armor is at odds with previous lore descriptions of late-generation power armor &mdash; even within the games published by Bethesda. Apart from the earliest variants of the T-45 (which were mentioned as using disposable power cells at an alarming rate), suits like the T-51b are noted for having personal fuel systems capable of lasting centuries. By contrast, fusion cores, even in mass numbers, can only grant a few hours of usage. Third, however, is the most 'accurate' rendition to date with regards to the size of the armor, its general movement and abilities. Unlike the descriptions regarding power armor from previous Fallout games, the power armor frame does not appear to make use of any recognizable form of unified hydraulics system for strength enhancing purposes (unless they are somehow hidden inside the armor segments or the base frame itself). It instead appears to solely derive its strength boosting abilities entirely from servo motors strategically placed within key points of the frame. The frame does not include armored gloves but rather entirely separate mechanical hands controlled by the operator inside. The frame is capable of boosting the Sole Survivor's strength beyond the normal S.P.E.C.I.A.L. limit of 10, potentially going as high as 14 with proper mods. Last but not least, power armor helmets have fully functional headlamps that are used in place of the Pip-Boy lights, and the lamp can even be customized to feature different colored light filters or use a particularly bright light in place of the default one.

In Fallout 4 power armor has had several alterations in regards to its physics, mainly the prohibition of swimming, with the user instead walking across the bottom. This makes wearing power armor at places like Libertalia risky as if falling off the walkways one will sink to the bottom and have to walk to shore.

Locations
Power armor frames can be found at numerous locations throughout the Commonwealth, both on NPCs and placed in-world. Almost all frames spawn with armor pieces attached. The type of armor found on most frames is determined when the player character comes within range for the first time, regardless if the player character sees or interacts with the armor at all. Depending on the frame, the selection of armor may be fixed, based directly on the player level, or randomized, and may also be affected by the level range limits of the location (see notes for more detail).

Owned
If worn, frames can be stolen by destroying or pick pocketing the fusion core.

Barter

 * Atom Cats Garage from Rowdy. Also sells Atom Cats T-60 pieces, sometimes T-51 pieces, and rarely X-01 pieces.
 * Commonwealth Weaponry in Diamond City.
 * KL-E-0 in Goodneighbor.
 * One can be ordered from Proctor Teagan on The Prydwen.
 * It is possible to purchase more than one from vendors. Just come back in 48 hours.

Bugs
}}
 * If wearing a suit of power armor, one can enter another frame. But this will delete the first suit.
 * If the player later enters and then exits the duplicated suit, their pip-boy may bug and turn invisible. This can be fixed by reloading an older save.
 * One cannot attach a piece of power armor if it has stacks. e.g. if having a stack of two X-01 torso then one would not be able to attach such piece. This is remedied by simply clearing the stack until one remains, one should be able to be attached to the power-armor piece once more.
 * If one tries to modify a power armor frame that has no pieces on or in the inventory, the Sole Survivor can become stuck in an inescapable animation loop. Loop stops after about 30 minutes if waiting. One can get out of this by using the movement button rather than the back button that would've been used to exit the modification menu, similar to getting out of chairs while sitting.
 * If one brings all companions to the Red Rocket truck stop all equipped in full X-01 power armor, calls the companions with the bell then fast travels to Sanctuary Hills, then back to the truck stop, randomly a Brotherhood knight will appear to kill X6-88. The knight who appears is also dressed in full x-01 power armor with jet pack. All companions will then kill the knight and his equipment can be taken. Danse will not dislike the act.
 * Modifying an armor piece with a material mod (denoted 'X+' in the material mod menu) purchased from a merchant (tested with Prism Shielding purchased from Rowdy) and replacing the mod without backing out of the submenu will add a duplicate of the mod to the player character's inventory.
 * A bug has also been noted in the 24-32 level range, causing the X-01 to spawn with the appearance of a T-51 or T-60 Power armor set. In some instances, such as with the 35 Court spawn location, once the player character enters the chamber containing the armor the visual glitch will correct itself. If this glitch occurs, upon inspecting the components of the armor frame the X-01 appears to be equipped. Removing these pieces and re-attaching them to the frame has also been reported to fix the visual error.
 * Often the Raider at the Federal Ration Stockpile does not get into the armor, so may need to wait until respawn.
 * Sometimes the power armor at Mass Pike Interchange spawns in the middle of the commander's bed, becoming unusable by him or player. Fixed by going to earlier save, or by returning to Mass Pike Interchange at another time (may still be "stuck" in the bed, but can be entered). Sometimes commander sleeps through the battle and has to be awakened with a gun shot so he/she can get into armor.
 * If you "craft" with the nearby power armor station, it will move it from the bed to the crafting station. Then the player can use the armor.
 * If one is wearing a suit a power armor then exits the power armor and gets into combat while repairing the power armor attached to the frame, one will enter the armor and become unable to exit, being "attached" to the frame and armor. this can be quite problematic, in the situations of needing to swap weapons in combat, due to another bug concurring at the same time that prevents the player from pulling up the Pip-Boy interface correctly.
 * Reloading saves does NOT fix this issue either, making the glitch difficult, if not impossible to fix after it has occurred.
 * If several Power armor Frames are bought from a single vendor, the armor frames will be stacked on top of each other. When attempting to enter one of the frames, you will be unable to move and stuck in between suits. This can also happen to a companion.
 * Mass Pike Interchange has bug such that multiple sets of frame plus T-45 armor are respawned. Have seen as much as 13 sets standing around (1 lower level, 12 upper level). Getting crowded up there.
