Fallout 3

"Why go down with the ship when you can try to fix it?"

${\text{Initial level}}=2+(2\times {\text{Intelligence}})+\left\lceil {\frac {\text{Luck}}{2}}\right\rceil$

Example: A starting Intelligence of 5 and Luck of 5.

$2+(2\times 5)+\left\lceil {\frac {5}{2}}\right\rceil =15$

Repair is used to fix damaged equipment (bringing up its condition) by using up a second item identical or similar to the original. Repair also determines the starting condition of custom-made equipment.

Maximum condition

The Repair skill level controls the maximum condition the equipment can be repaired to. This is equal to

${\text{Maximum condition}}\%=40\%+\left(0.6\%\times {\text{Repair skill}}\right)$

Example: A Repair skill of 50.

$40\%+\left(0.6\%\times 50\right)=70\%$

In other words, every 5 points in Repair raises the maximum condition by 3%. For example, with skill level of 10 allows items to be repaired up to 46%, skill level of 15 allows repair up to 49% and so on. This is important because weapons and armor in poor condition are not as efficient and their value is decreased. Low quality weapons have less accuracy and damage, which reduces effective range and often causes more ammunition to be used to kill enemies when using ranged weapons, or more hits when using melee or unarmed weapons. Ranged weapons in low condition are also more likely to jam, which lengthens the reload animation. Armor in low condition has a lower Damage Resistance (DR) rating. If the condition of a weapon or armor/clothing is completely neglected, the item will break, making the item unusable until it is repaired (armor and clothing will remain on a character after it breaks, but can not be put back on if taken off).

Repair efficiency

Furthermore, repairs become more efficient. The final item condition from repair is equal to:

${\text{RepairedCondition}}=5\%+{\text{HigherItemCondition}}+\left(0.05*{\text{LowerItemCondition}}\right)+\left(0.15\%*{\text{RepairSkill}}\right)$

up to the maximum condition allowed by your repair skill

Example, combining a minigun with a condition of 20% into a minigun with a condition of 10%, by the player character with 10 points in Repair:

$\left(5+20+\left(0.05*10\right)+\left(0.15*10\right)\right)=27\%$

The same repair performed by the player character with 50 points in Repair will give:

$\left(5+20+\left(0.05*10\right)+\left(0.15*50\right)\right)=33\%$

Other than determining the item type, it does not matter if one repairs item A with item B or the other way around. The formula also works when the two items have different item HP even if one of them is unique — the item condition percentages are taken into account, not HP.

As can be deduced from the formula, the player character's Repair skill is the determining factor, the item used for repairs contributing 5% max to the final state. This can make using or even buying items in good condition for repairs uneconomic. On the other hand, using broken items, which are worthless at 0% condition, is still somewhat effective.

Notes

• Repair is used to disarm certain traps (bear traps, pressure plates, etc.).
• Due to their presence in repair lists, common variants of weapons can be repaired with unique weapons, with the potential loss of these rare items.

Fallout: New Vegas

In Fallout: New Vegas, items can now be repaired to 100% regardless of the player character's current skill. Repair still governs the effectiveness of repairing one item with another, using the same repair efficiency calculation as Fallout 3, but with a static 100% condition limit in place of the skill-based limit.

A higher Repair skill unlocks crafting recipes for different types of ammunition and other gear at reloading benches and workbenches, most notably the Weapon repair kit with 50 skill. High Repair also allows one to repair mechanical or electronic world objects (elevators, doors, computers, etc.).

Non-player characters who repair

Name	Location	Repair cap
Dale Barton	The Fort	58%
Samuel Kerr	188 trading post	64%
Calamity	Jacobstown	76%
Old Lady Gibson	Gibson scrap yard	79%
Mick	Mick & Ralph's	85%
Joshua Graham	Zion Canyon	100%
Paladin Sato	Brotherhood of Steel safehouse	100%
Raul Tejada	Black Mountain / Raul's shack	100%
Major Knight	Mojave Outpost	100%
Sink Central Intelligence Unit	The Sink/Big MT	100%
Commissary terminal	The Divide	100%

The Repair skill of an NPC dictates the maximum condition they can repair to, based on the same maximum condition formula used in Fallout 3. The total cost to repair is independent of the one's Barter and Repair skills and is calculated with this formula:

${\text{Repair cost}}=2\left({\text{Value at max capped repair condition}}-{\text{Value at current condition}}\right)$

If repairing an item were to increase its value by 1000 caps, the repair would cost 2000 caps, essentially a 100% overhead.

Notes

• Non-player characters will not repair apparel (such as Benny's suit) that has no DT.
• Normally, common weapon variants can not be repaired with unique weapons unless the Jury Rigging perk is selected, which can result in the potential loss of these rare items.
• Items whose HP values still round to 100% will not offer the option to repair/maintain them, even if they show less than maximum cap value, and will not appear in the list of spare weapons when repairing another of the same type.
