Scavenging

While adventurers will routinely uncover treasure during their adventures, certain characters might have a greater ability to "feel" their way through different piles of wreckage or trash to uncover salvageable items. Scavenging can accomplish three different objectives: Additional Loot that can be sold for gold or used for specific quests, Additional Items that could be magical, Gathering Profession that can be used with the Reforging Profession.

Scevenging can also be a useful way to acquire gems for the Enchanting profession.
