ok the montinuars on lvl 1 dungon drop the right side of the skull u can kill either the lvl 27 or 12 the fleshcrawlers on lvl 2 dungon drop bottom half of the septre the catabo things on lvl 3 dungon drop the top half of the septre and the ankou on lvl 4 dungon drop the left side of the skull, i would recomend u tackle the lvl 75 ones instead of the 83 and bring food, the highest they hit on rune aromour is 8
