My Adaon have one ring of unlife, but iron golem as shield and high staff damage are enough for me. Just I wan't to first clear lambar cave or mercian crypt(my main target is nr 2, with very strong death staff), eventually I will second time complete Castle Storme. Later I defeat Void Lord...
I kill Araim, Mausoleum lich, Glibra (rumor boss), High Priest and Abbot. That's all? But i don't kill Void Lord (and any dark presence) and Lord of Pit
And I collecting limited and unique items, so maybe i take bishop ring for my collection?
Also remember that it's easier to get xp than unique...
i have now earth elemental lvl 14 (with summoner III and earth master II) and never use companions, they steal exp
but maybe i finish trial and error and get staff of malan
and i have to finish this quest with Adaon?
