Fallout 3 crafting

Basics
Schematics allow you to create homemade weapons, provided you have the proper components. Acquiring multiple copies of the same Schematic will allow you to make weapons with higher initial condition at the time of construction.

It's a good idea to hunt down additional copies if you plan on using the weapons often. Obtaining more than one copy of the schematics will upgrade the plans. Two plans makes the initial condition of the weapon at construction equal to your repair skill (75% of your repair skill with just one blueprint). Three plans will net a condition of 125% of your repair skill at construction.


 * 1 Schematic ---&gt; 75% condition of your Repair skill
 * 2 Schematics -&gt; 100% condition of your Repair skill
 * 3 Schematics -&gt; 125% condition of your Repair skill (+25% Item HP)

Additional Schematics for the Bottlecap Mine and Nuka Grenade allow you to make more instead of giving more damage. With one schematic - you make one. With two - you make two. With three - you make three.

Note: Additional Schematics cease to yield benefits after three of each kind have been located. They will simply appear as items in your inventory. Also, the produced weapon's condition is still capped at 100%; A third-level schematic with a Repair skill of 100 will still produce weapons at 100% condition, NOT 125%. As such, the third schematic becomes pointless once Repair is elevated to 100. (Bottlecap Mines and Nuka Grenades excepted)

Higher repair lets you to make homemade weapons that have higher starting condition and damage. As you make multiple copies of the same weapon you can combine them with the repair skill for higher condition and damage. Alternatively you can have an NPC repair them. Note - the Bottlecap Mine and Nuka Grenade are always max condition and rely on the explosives skill for more damage.

Contrary to the in-game text, additional Schematics do not increase damage. (For example, every version of the Shishkebab Schematic creates item 434e). As the base item is the same, the base statistics are as well. The only change is in its condition (or number, for the Bottlecap Mine and Nuka-Grenade).

Note If you have the Warmonger perk, all the schematics you acquire afterwards, will be render as "junk" item and can be dropped to the ground.

Appearances
Schematics appear only in Fallout 3.
