The Scavenging attribute increases the amount of output and skill xp you get from
Formula: +1 item = x/65 points
+1 skill xp = x/125 points
For each level you get 5 attribute points, that would mean +1 item output for every 13 levels, if you invest them all in xp boost. That would also mean +1 skill xp every 25 levels, if you invest them all in xp boost.
