It kind of works with my schedule right now since I've mostly been able to play a few minutes at a time, so I can kill the trainers and masters, leave the room, exit and come back later when they've respawned.
I sold off all my small rocks after using skill points on Magic Finder so I could get a new estimate, and I'm currently at 26 small rocks.
Update (1/10/12 - 10:30pm pst), just got my first RoLS at 51 small rocks

Its not just luck though, I spent 10 skill points on Magic Finder so its great to see it paying off. I definitely find the 1% less cc compared to polished ring of backstabbing to be worth the trade off for the extra AD potential, extra AC, BC and shadow regeneration.
---------------------------
Now that I'm using the ROL and don't need the cc% items, I've replaced the Villain's armor with Superior hard leather armor, and replaced Troublemaker's gloves with the GoLF - I know its less AC, but I wanted the extra HP boost, and to actually say I'm using it
