Idol Worship

Description
After the Arisen has spoken to the Duke, Caxton will inform him/her that he wants a prized idol as a status symbol to get better supplies for his store.

Deliver him a a Gold, Silver, Bronze or Cursed Idol to get access to better equipment in his shop. Note that you can only give him one idol; a Gold Idol cannot later be given to him if you've already given him a bronze one, for example.

The Gold Idol you get from an Escort Duty quest for Symone, which can be started by talking to Fournival after completing Land of Opportunity and Chasing Shadows.

The Silver Idol is acquired as a reward for completing Put the Eye Out, which can be obtained from the Pawn Guild Notice Board.

A Bronze Idol can be found in the lair of The Dragonforged at Hillfigure Knoll, as well as Selene's Hut in Witchwood.

A Cursed Idol can be found just outisde The Abbey in the center of a circle of flowers.

Depending on which Idol you give him, he'll start selling equipment of varying levels. Giving Caxton a Gold Idol will give you the best upgrade to his inventory while giving him a Cursed Idol will net you the worst upgrade to his inventory, with Silver being better than Bronze. Choose wisely.
