i just gm'ed this last week. i found it to be real tiresome to just wander the realm and pick chest at random for minimal gains at best. suprisingly enough, i had better results just staying put in one spot. sometimes it went a few gains beyond the daily .1..... but never got dramatically over that ( i never put in 10 hour days though)
i got the best results at ice.... where the arctic ogre lord spawns right around the corner from the entrance. sometimes people wont be there so you can also spend some time whacking the ogre around.
