For this code you must be a Sensate. In the private sensorium activate the
green stone where you talk to ravel (Make sure you've already talked to
her once) then activate it again and answer in the following order: 1,1,1,2,1,1,1,1,2,1
for 6000 exp repeat as necassary.
First, talk to the woman at the bar who isn't a dustman. Then tallk to her
again giving the answers 1,1,1,2,3. She gives you 50 coppers and you can
repeat it over and over again.
In the market with Karina, talk to Karina. Then talk to the Harmonium Officer.
He is looking at Karina. Tell him to go to her. Then talk to Karina and
she'll give you some exp. Keep doing thi and she'll give you more.
