Salvage

Salvaging is a process used in order to garner common crafting materials, rare crafting materials, runes and weapon upgrades from salvage items, weapons and armor.

All items except for most quest items, weapon upgrades, runes and all unique items can be salvaged for crafting materials. Highly salvageable items, once identified, provide substantially more materials than other items.

Salvaging can be carried out using the following 'kits':

(Basic) Salvage Kit
The Salvage Kit is often referred to as the Basic Salvage Kit. This kit will only salvage common crafting materials from items. If an item contains a rune or weapon upgrade then a basic salvage kit will not retrieve it nor does it salvage rare crafting material from any salvagable item.

Expert Salvage Kit
The Expert Salvage Kit will salvage common crafting materials and rare crafting materials along with weapon upgrades and runes

Superior Salvage Kit
The Superior Salvage Kit will salvage common crafting materials and rare crafting materials along with weapon upgrades and runes.

Keep in mind that even with the Superior Salvage Kit, it isn't always 100% to get you items out of already modded armor or weapons, but with it you do have a better chance.
