Fallout 4 Power Armor

Power Armor is a unique form of external armor $$

Background
Power Armor is a multi-component armor unit, comprised of a base frame, with assorted armor pieces mounted on it. For Power Armor to function it requires a fusion core as a source of power, which drains over time and actions that consume AP will increase the rate of depletion. Once the fusion core is drained 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. or hold breath when aiming with scopes. Power Armor in Fallout 4 requires no training to use.

Power Armor is capable of boosting the Sole Survivor's strength beyond the normal S.P.E.C.I.A.L. limit of 10 to 14 with modifications. Wearing Power Armor negates any bonuses given by standard armor. Power Armor helmets have headlamps that are used in place of the Pip-Boy lights, which are disabled while wearing the armor. While in Power Armor, the player character is incapable of swimming, with the user instead walking across the bed of any given body of water. Handheld or wrist-mounted weapons such as knuckles cannot be equipped.

While wearing helmeted Power Armor, the Sole Survivor can remain underwater for an extended period, but after several minutes submerged the drowning animation will play, and the player character will lose health rapidly and die. Power Armor completely negates all fall damage, with or without any pieces of armor attached, enabling the wearer to fall without any harm to either health or the armor itself. This alerts any nearby enemies of the player character's position. Landing on or in close proximity to an enemy or even friendly NPC deals a great deal of damage to them from the fall as well, which may cause them to become hostile.

Companions
Companions can be instructed to enter Power Armor via the companion command system. This is done by selecting Talk when facing a companion, then instructing them to Enter Power Armor when the player character's crosshair is over the Power Armor suit they wish for them to occupy. Certain companions (e.g. Nick and Hancock,) will remove the helmet by default. One can force them to wear the helmet by equipping it from the companion's inventory, as with standard armor pieces. To have a companion exit Power Armor, select the Talk dialogue option and Relationship will have been replaced by Exit Power Armor. Some companions however are unable or will refuse to use Power Armor. Paladin Danse will refuse to exit his Power Armor and cannot be assigned to another suit. His Power Armor also does not degrade from combat or fall damage. Companion worn Power Armor does not drain the fusion core if it has one installed and can use core-less frames without penalty.

Maintenance
The parts may be repaired and modified at Power Armor stations located around the Commonwealth, where a Power Armor frame is installed at, or within close proximity of the station. The armor and frame can neither be renamed nor scrapped for component materials. Power Armor stations can be built at settlement locations under the crafting tab in workshop mode, if the player character has the necessary perks.

There are six tiers for each Power Armor piece, each granting higher damage resistance and health. The amounts of materials required for upgrading Power Armor pieces are fixed for each specific item, which means improving an armor piece from tier E to F has the same material cost as upgrading it from tier A to F. Depending on the player character's current situation, it might sometimes be wiser to postpone the next upgrade until higher (or the maximum) ranks of Armorer and Science! have been unlocked in order to save resources. This is especially true for the more advanced Power Armor models as they require much larger quantities of increasingly rare and specialized materials for their upgrades than for example T-45 or raider Power Armor. The helmet's lamp can even be customized with different colored light filters or a more intense white light in place of the default one.

Leveled
Most Power Armor located around the Commonwealth is level scaled, up to [[Mod:Creation Kit/Encounter Zone|maximum level] of an area. For example, at lower levels, one will find T-45 Power Armor though at higher levels it can range from T-51 Power Armor up to X-01 Power Armor. Leveled frames spawn with T-45 pieces at levels 1-13, T-51 pieces at levels 14-20, T-60 pieces at levels 21-27 and X-01 pieces at level 28 and above. The upgrade level of armor pieces also increases within these ranges, e.g. T-45b armor will spawn starting at level 11. The armor pieces generated do not include previous levels, e.g. a leveled frame encountered at level 26 will only have T-60 pieces.

Frames sometimes spawn with incomplete sets of armor. Randomized frames can spawn with raider pieces at any level, T-45 pieces starting at level 15, T-51 pieces starting at level 25, T-60 pieces starting at level 35 and X-01 pieces starting at level 45. The armor pieces generated include all previous levels, e.g. a randomized frame encountered at level 26 can spawn with any combination of T-51, T-45, and raider armor pieces.

The leveled Power Armor list adds additional armor sets at following player character levels:

The only exception to this is the suit of randomized parts, which have their own separate pool (per component) to draw from:

Locations
The parts of armor (ex. body, head, etc.) are in a fixed number and type for each spawn point. Some frames appear to spawn different parts by loading a save from before ever entering that area, but the type of armor (e.g. T-45, T-51, X-01, etc.) depends on the player character's level when entering the area for the first time. Additional Power Armor pieces of any type can be purchased from Rowdy at the Atom Cats garage.

Owned
If worn, frames can be stolen by destroying or pickpocketing the fusion core. Whenever a player character enters a stolen frame, if there are Power Armor pieces equipped on the frame while doing so, companions that the player character currently has in tow, or within the area, will consider the act as "stealing" and the player character's affinity with them will change accordingly.

Behind the scenes
Power Armor in Fallout 4 was designed by art director Istvan Pely.
