Okay guys I made it this far now I need 12 Titan Runestones. I know I can only get them off of the last 6 bosses and that Li Shen is a dependable drop. Right? And the other bosses have a 30%ish chance of dropping one. My questions is, can I run Pinnacle repeatedly and get one off Li Shen each time, or is it only one a week? I assume I can get one on LFR and 1 from 10 man. I want to get this done asap, any help is appreciated.
