Chest Farming Guide

First off, this guide is meant for rogues or druids, since both have stealth, and lock picking is a must.

To begin, you have to designate one rogue or the druid to be the 'Meat Shield'. Start off by wall jumping up the wall to your immediate right as you enter (the exit after the final boss of ramparts).

From there, make sure you and the partner are both in stealth, and watch out for the circular patrol that can spot invisible units. Rogues and druids will know this by the light blue circle that appears above the NPC's heads when you are stealthed. Next, distract the circular patrol when they are far away from the chest, and here's where the meat shield and a bit of hope comes in. Have the other rogue sprint and evasion towards the chest, then off that area you wall climbed up (for a druid, use whatever speed boost you can). This will cause the NPC's to leave the chest and follow your partner, and they cannot follow all the way down, making them evade glitch to my knowledge. While they are trying to go after your partner, you should be free to pick the lock on the chest (if the locked one is currently in that position) and grab the loot. Congratulations, that's chest one.

Either vanish and go for the next chest, which is by the first boss, or leave and reset the instance. If you are going for the second chest (which when you actually do the instance, is the first chest), you'll have to wall jump back up towards that circular area. Distract the NPC's that patrol that rim far enough away that you can walk through the middle of that ring, into the hallway, and down the spiral ramp. You'll be in the room with the first boss and his two healers. Make your way through that area until you get to the next chest, again with more stealth detectors. Use the same plan as before, one person leads them away, the other grabs the chest. Congratulations, that's chest two.

I cannot stress enough, though, how much patience you need to have around those stealth detecting units. If you watch their path and time their path, you'll save yourself a hefty repair bill, and wasted time. One more thing that can compromise your chest nabbing is if your partner gets dazed and killed before you can open the chest. My rogue friend and I both were able to farm these chests with minimal problems, even with dazed effects (wasn't dazed too often). The only thing about farming this method, you have to/should split the profits 50/50 with your partner.
