An old function in Season 1, where you could find scrap metal and turn it into something useful. Highly unbalanced weapons, nearly free. Removed, after Sheila muscled her way into the weapons market, and used her favourite Shotgun to kill off any unfair competition. Well, new weapons are for more reliable than weapons made out of junk you found in a Scrapyard anyway, right?
Now no longer relevant, though a Mystical Scavenging skill remains a Buff for a few races. The more proficient you were in scavenging, the more money you could make from it. Easy abusable, people made weapons from scrap and undermined Sheila's prices.
