I'm trying to complete the Drain Bolt VIII quest, and it asks me to kill one of the Valkor Guards and obtain one of their skulls. With some help, a few of the guards (which were around lv103 with 17k health) were killed and I looted them all, but did not get a skull. One of the people helping me said that he got his skull on the first kill, and said the quest might be bugged due to a change in mobs and that the loot for them may have not yet been fixed. Can any one confirm this or am I just have a bit of bad luck with the skull not dropping?
