Keep inmind that you will want to lockpick in the area that is current for your level if possible. if for example if you are 50th and your lockpicking is 100 you will need to go back to some lower level areas and then work your way up to the more difficult. hope this helps.

This location is very easy to find using the coordinates: 52,45.

If you stand at a particular spot. You have the ability to unlock 4 of the five Practice Lockbox's there. (Screenshot Provided).

Just in case. The words "Practice Lockbox" will ALWAYS be yellow. The word "Locked" changes colors the way Ebonstar says.

You should stay there with the practice boxes until you cannot level your picking skill anymore (when the word "Locked" becomes gray).

The boxes respawn very quickly, and sometimes they are booby-trapped. ( I had the Frost Hold Magic trap. )

I was able to gain 101 skill points from this location. I went there with a skill level of 4 and left there with a skill level of 105. Not Bad - Now I go back to the Zoram Strand!

There are numerous creatures outside. But you do not have to worry about them coming in to attack you (at least I did not have to). My stealth was good enough to walk past all creatures - INCLUDING horde. So it is possible to make it there without a fight. In case you are just trying to get your picking skill up.

Good luck,

The next picking area for me was:

Duskwood Chest

So it was no hassle getting higher skill. All I had to do was kill the one spawn every time it showed up. I got to open the chest several times before he showed up. After that, I went to Desolace - in Kalimdor:

Area of Lockboxes

The pins are not the actual lockbox locations. But it is the area you should be in. Just be sure to bring something to breath under water with, as the boxes are ALL underwater, and you should have the ability to kill a level 33 mob.

I am now level 46, and my picking is maxed at 230. The Desolace boxes are still green for me and only take about 4 to give me one skill point.

At a 230 skill level you can open most of these on the list:

Sturdy Junkbox - 175
Heavy Junkbox - 250

I'm on the Mannaroth Server, and I very rarely see any Horde there. For that matter, I rarely ever see Alliance there either. Plus, you're under water.

The certificate is to hang on the wall and show everyone that you are a certified klepto.....won't your mother be so proud!...but seriously, it is just a certificate, you don't use it for anything.&nbsp The purpose of the quest is to get you trained up in lock picking so you are able to use the skill for the other quests to come that involve picking locks.&nbsp The very next rogue quest involves picking a lock in the tower in SE Westfall.

Now Alther's Mill is down the road east of Lakeshire. Follow the road east from Lakeshire till you come to a fork in the road, head down the right path (dirt path) Watch out for the lvl18-20beasts. The mill should be a building with a big saw in the middle.

At Lvl 16 the maximum lockpick skill you can get is 80, so practice on the locks till you get 80.Your maximum lockpick skill increases by 5 every time you gain a level

The reward he gives you is useless and can be destroyed or put in the bank. It has no furthur use so its trash.

Need Lockpicking of 25 to open the chest. Coordinates at 52,41. Training Chests go yellow at 30 and green at 55.

In the room is a box marked "Lucias's Lockbox".&nbsp There's also a number of practice locks.

Use the practice locks until you reach level 75.&nbsp Once you reach about 25, you will never fail again.

Once you reach 75, you can open Lucias's lockbox.&nbsp I'm stil not sure what the certificate is for, but I got 1550 XP for finishing the quest.

Go to Lakeshire

*Ironforge < Stormwind < Lakeshire, Or if you havent been there yet, Follow the road East of Goldshire until you come across it*

Head north up a path for about 10 seconds, then turn Right on a dirt path, Walk a little and you should see what looks like a lumber mill, there are about 6 pracitce lockboxes there. They keep respawning too, They should get you to at least 100 lockpicking in 5 - 10 minuites
