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 the 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, which 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 user 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, characters interact 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, 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. Finally, instead of gloves and boots, the power armor frame has a set of fully articulated mechanical hands and feet, which mimic the wearer's hand and foot movements via controls in the shins and forearms, increasing the wearer's arm length and overall height by about a foot.

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 (as the frames with their plates affixed are heavy enough to crush bear traps by stepping on them), 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 character's 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

 * 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. After this, location stopped all respawning, including Gunners and all items.
 * Wayward Pines Motel has similar bug, has created 3 sets of Raider Power Armor at location. Raider used one, leaving two behind at last count.
