Repair is a skill in Fallout 3.

Initial level[]

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

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

Example: A Repair skill of 50.

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:

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:

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

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.
