finally got this guy...not sure if it was luck or plain coincidents...
after hunting this guy off and on for 2 weeks, approx 15hrs...i was bored and took out the 3 goblins from the camp...low and behold look who shows up, tainted followed very shortly by the corrupted...
saw a previous post about killing the cyclops from the neighboring isle and thought i might try something different as well...
thats my 2cp...
