Ok, so I know this has been posted before, but not with additional information I provide. Common sense, again, sure, but not practiced too often from what I’ve seen.
What is it? The wonderful pickpocket ability. All rogues know about it, but how many of you actually use it? If you do, kudos. If not, start!
***EDIT*** -- Changing this around a bit, came up with an easier way to do it.
One of my favorite places to pick currently, is Auch Crypts. The level of these mobs make it easy to maneuver around all of them without ever being caught. I have also never been resisted here, and never had to vanish b/c I got too close. The first thing you want to do is make sure "Auto-Loot Corpse" is checked in interface options. This way, all you have to do is put pickpocket somewhere easy to reach on your hotkeys, (I use it in 2), get close enough to the mob, press 2, and keep walking, never even having to stop to click anything. I can make it from enterance to Maladaar in about 6 minutes, hitting every pickable mob along the way. Once I hit the boss, pick him, and attack. Of course, put all your durability gear in your bags first, so you don't run into repair costs. Make the run from spirit healer to instance, and do it all over again. On a single run, I make anywhere from 5-8G just in coin, sometimes grab a gem or two, a whole host of vendorable items, and sturdy lockboxes. These lockboxes are where a lot of the G can be made, and also helping to max our your LP if you haven't done so already.
In these, the crazy Arena days, other rogues are ALWAYS looking for blinding powder, as they’re used so frequently in the Arena. Junkboxes of ALL type almost always contain blinding powder, or flash powder. I usually keep 40 or so flash powders on me, just to have plenty for Vanish, and vendor the rest, but those blinding powders sell for a very nice chunk of change. I pull anywhere from 2-4G a stack depending on amount sold and how nubish the other rogue is.
If you want to take the blinding powder and use it to your full advantage, hit some of the older instances. BRD, SM, really anywhere, all the boxes I’ve found have contained one of the types of powders, as well as other poison-making herbs you wouldn’t have to otherwise buy from poison vendor.
Also, if you start running out of room in inventory, there's a vendor just outside SL gate, so you don't have to make a long run to get rid of trash =)
Hope some of you find some use out of this =)
