Hey all. Wheres the best place to get clue scrolls? Ive searched the forums but no mention. I spend forever killing werewolves, but they dont drop anything. I move to goblins and get 2 in 10 mins! Only problem, both of them were rubbish (pickaxes and studded chaps) Im lvl 55, so I cant go killing the lvl 90 monsters. but which NPC is best for decent drops more often? Cheers all Sindaaran
