Well after reading alot of guides here and seeing people trying to get out of leacher by posting obvious guides I am quite hesitant to post this. But here goes.
Everyone knows about the scarlet strath runs to try to get orbs and blues. Many times I have taken 30 mins or so to clear out the side only to get one orb. So I figured a better way to do things.
All you got to do is stealth right up to the Grand Crusader Saidan Dathrohan who is of course the last boss across the hall from the final boss, dispatch him quickly loot the righteous orb that ALWAYS drops along with the blue and possible green.
Pop in kill the last boss, take your gear off die, run back in reset the instance rinse and repeat. You can get 5 guaranteed Orbs in less than an hour, and depending on your server they can go from 50g a pop on up.
I am not an enchanter so doing enchant runs is out of the question, this was the 2nd best thing I could come up with to make some good cash really quick. I usually make my run, hearth to shat, go farm for an hour or so then head back and get 5 more orbs, just keep rinsing and repeating. Hope this helps some of the more casual players who cant spend the hours upon hours farming.
