I logged in on my treasure hunter in training tonight intending on getting him his GGS gain in Lockpicking, my dreaded foe, then log off and go to bed. I opened the bag of twelve boxes in my bank, and started my usual routine. I locked them all, and started picking; on the second box I got my GGS gain. On the fourth box I got my second. The sixth my third. Forty-five minutes later and I've gained 3.5 points, from 81.1 to 84.5. I must say, I like this better than grinding for hours for a .1 or two.
