So despite Guardians no longer being a thing, this (at least) still drops. When trying to use, as a lvl 10 Pastamancer, it gives the message,
"You're not really sure what to do with this thing..."
- It adds weight to your Pasta Thralls. You get that failure message when you try to use it without a thrall out. --Prestige (talk) 22:47, 22 November 2013 (UTC)
I can confirm that this drops from the Grave Rober Zmobie in the Alcove. --Phantomreader42 00:08, 17 April 2009 (UTC)
Also got one from a corpulent zobmie, so it can drop from both listed alcove monsters. Seems relatively common but I don't have the chance to spade the exact drop rate. I'll try deleting the content request since the drops needing confirmation are confirmed. --Phantomreader42 01:17, 17 April 2009 (UTC)
