Fallout: New Vegas crafting

Characteristics
Crafting is used for building a large range of things, which means items have a lot more practical value than in Fallout 3. Crafting covers the creation of custom ammunition with the Repair skill, custom weapons with the Science skill, and the creation of food and medicinal items with the Survival skill.

Conversion (charge variant)

 * ¹ Requires Vigilant Recycler & Gun Runners' Arsenal
 * ² Due to Vigilant Recycler having Science 70 as a pre-requisite, none of the Optimized recipes can be made at the skill listed in the workbench.

Production

 * ¹ Without Hand Loader perk, it can also be made using a schematic.

Poisons (venoms)
All poisons are created at campfires. Poisons are used to coat melee or thrown weapons and can have massive effects on your enemies. Note that one dose of poison is enough for one application to an enemy.
