While experimenting at the Auction House, I noticed that there were several copies of a particular Legendary necklace, called "Squirt's Necklace," for sale for crazy prices. I know that Squirt is a merchant in the Bazaar during Act 2, but I didn't see her selling this item, and she heavily implies that she would hurt me if I was to try to take it from her directly.
It's a level 24 necklace from what I understand, so it would work well with my mid-to-late 20's Witch Doctor. However, the prices for this item on the AH are crazy high.
Is there any reliable way to get this item? Does it drop from some particular boss or mob? Does Squirt sell it under certain circumstances? Or am I just supposed to get lucky?
