Merchants buy and sell all manner of items, but I'm only interested in their works of art. Good art is like a balm for the soul. Please do let me know if you get your hands on any, Professor!
A trader is visiting the market. Try to trade using the item Ignatz gave you.
  1. Accept the quest from Ignatz.
  2. Do some trading.
  3. Report to Ignatz.
What a remarkable piece of art! Masterful works like this normally go for steep prices. You clearly have a knack for dealing with merchants.
