I have been fighting lately in the LOIO area, near the Sarnak fort. I have been overwhelmed by having to destroy these and goblin warbeads, I almost hate to loot the bodies after the fight is over. They are there and if you go into the zone and shout for someone to let you know when they have some, I am sure you can get them.
