Colossal Scimitar - where to farm and drop rate

  • Hey guys, I would really like to get a colossal scimitar by farming it myself. I tried moddok crevice for several days and easily about 80 runs without any luck. I switched to farming the corsairs in Zehlon Reach but nothing so far. How goddamn rare is this thing? Idc about req or anything, just max dmg with insc slot would be fine. Can anyone suggest other strats if I want to get it myself? Or is it that rare and I should expect farming for weeks?
    I have got the feeling that Zehlon Reach might be better than Moddok Crevice because I get somewhat regular weapon drops from the warriors there while in Moddok crevice they hardly drop anything beside armor pieces.
    Any advice would be appreciated:-)
