WOW Rogue+Other Class GOLD MINE

Ok so I am kind of well geared. I am a human rogue and I’m speceed combat dags, which is a bad choice for this, I should be combat swords or something but anyways.
I also have imp sap. Go to the crypts instance in auchdoun and stealth to the very end of the second room.
Odds are there is a chest there that is locked or un locked, but w/e. it is guarded by 2 elites, 1 is imp sapable, the other is not but no worries if u imp sap the immune one nothing bad will happen. imp sap the non immune one, kill the other elite, who is level 65-66. Beware he spawns 2 adds usually that are random, so use COS and blade fury if u got it. that with adren rush and evasion is kickin.... so kill the first mob, and depending on your heath afterwards... it varies from almost dead to more than 75%.... either vanish or kill the other mob, he also spawns 1-2 mobs.
Loot chest and you’re done. Also as a bonus, there is usually an anchient lichen/ adaman mine right there as well. I’ve gotten 2 BOE blues, 1 living ruby and some other gems/green d/e fodder. 7g per chest in gold as well.
Enjoy and GG BLIZZ. I’ve also seen a 70 priest do this, holy spec using mind sooth to make it to the end of the room, and into a corner. Then mind control one mob, use it to kill the other and be burned down itself. Then dps it the rest of the way. Should be easy
