Perk Rank 2 savings
As for Patch 14, the saving you receive during crafting of weapons while rank 2 is equipped are varying by material. In the picture below is an crafting mats example of a Level 45 Gauss Rifle (Fallout 76). The left "Requires" Column shows the crafting mats without this Rank 2 equipped perk card, the right column the same with the card equipped. The lowest saving in this example is ~28% for Screws and the highest Springs with ~57%. As a rough estimation you can expect about 30% savings by using this fully ranked up card.
