Improved Scavenger armor
The new medium armor Improved Scavenger (helmet, outfit, gloves, boots) is crafted at the Improved Workbench once you have Master armorer 4. Its protection matches the improved Ranger armor, and it helps with salvaging: more XP, faster salvaging, a chance at an extra part and lower stamina use.
The full set raises your Loot Stage (by up to 40% at quality 6). When you salvage cars, trucks, air conditioners and other machines, it also gives you a guaranteed alloy.
The table of values by quality is in Improved Scavenger.
