Iron Gut

 is a task in.

Synopsis
"Iron Gut" Pietro swallowed a valuable gemstone - Ngati's Black Tear - to avoid its theft, but now he's unable to pass it through his system. I've offered to help him "retrieve" the stone.

Walkthrough

 * Talk to Rosanella at the Radiant Court about a medicinal concoction that might help Pietro purge the gemstone he swallowed. She will provide a list of the ingredients for Ondra's Bile - a Rotten Hagfish, an Unripened Palm Stone, and a vial of Fire Kelp Extract. The stuff will keep him going from both ends for a week or two, but is guaranteed to work.
 * The rotten hagfish can be found in one of the crates at Lifter's Refuge.
 * The unripened palm stone is sold by (or stolen from) a merchant, Birna in Radiant Court.
 * The fire kelp extract is sold by Jacob Harker for in The King's Coffin, you can also steal it from him.
 * Bring all of the ingredients to Pietro and make him throw them up.
