Seems like all the casting goblins on Kunark drop them... they all have different names, but the stats on all of them are lore, no drop, 3cha. Also seen: iksar witch doll, koa'dal blood doll, etc. Don't believe there's any quests for them, at least none I've heard of (and these things have been in the game since Kunark...) can be useful if you need a little charisma boost, though there's much better charisma items out there.
Also, casting lizardmen in Feerott and Rathe drop a series of 3cha dolls as well.
I think it's just screwed up pathing allowing them to attack you from inside walls; I was being attacked on the bridge at the goblin camp yesterday by a mob I couldn't see and would guess it had managed to get inside the bridge somehow. Pathing at that part of the camp is so screwy that my pet wouldn't even attack mobs right next to it.
Does anzone know what this is for? There are 2 other dolls with the same stats around. Alll equip in the shield slot. Seems pretty stupid if there would be no quest involved.
