So does anyone have a list somewhere of farm spots for specific option stones? I can't find any information about this on the forums.
Strange that no one else has asked.

I just got lvl 97 and from what I have seen so far , drop rates of useful option stones has been extremely low or even non existent. Do the good ones like Protection of Marea, Flag of Roha, Teardrops of Edoneh,DD option stones,etc drop only from boss mobs or something?
