Received this after killing both jesters. The first jester is found in the elemental masters wing.
West after portcullis.
East at junction after the demon door to go to the elemental masters' area.
North when you reach the choice between going NW up the steps and North at the end of the wizards' area.
Second jester: randomly placed in the second maze.
Don't pay him anything; instead tell him about killing his twin.
