The practical application of the Science skill, for fixing of broken equipment, machinery and electronics.— In-game description

Repair is a Fallout, Fallout 2, Fallout 3, Fallout Tactics and Fallout: New Vegas skill. In Van Buren and J.E. Sawyer's Fallout Role-Playing Game it was renamed mechanics.

Fallout and Fallout TacticsEdit

$ \text{Initial level}\%=20+\text{Intelligence} $

Example: A starting Intelligence of 5.

$ 20+5=25\% $

Fallout 2Edit

$ \text{Initial level}\%=0+3×\text{Intelligence} $

Example: A starting Intelligence of 5.

$ 0+(3×5)=15\% $

Fallout 3Edit

Bobblehead Repair

"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\times5)+\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 conditionEdit

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\%\times50\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 efficiencyEdit

Furthermore, repairs become more efficient. The final condition of the item being repaired is equal to

$ \text{Repaired condition}=\left(5+x+\left(0.05*y\right)+\left(0.15*Repair Skill\right)\right)-TIC $

Where $ {x} $ is equal to the % of the highest of the two items and $ {y} $ is equal to the % of the lowest of the two items, and $ {TIC} $ is the item being repaired, all of which are a 0-100 value.

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

$ \left(5+20+\left(0.05*10\right)+\left(0.15*10\right)\right)-10=17% $
$ \left(5+20+0.5+1.5\right)-10=17% $

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

$ \left(5+20+\left(0.05*10\right)+\left(0.15*50\right)\right)-10=23% $
$ \left(5+20+0.5+7.5\right)-10=23% $

Other than determining the item type, it doesn't matter if you repair 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'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.

  • 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 VegasEdit

In Fallout: New Vegas, items can now be repaired to 100% regardless of the player's current skill. However, Repair still governs the effectiveness of repairing one item with another. 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 the player to repair mechanical or electronic world objects (elevators, doors, computers, etc.).
