In the 2nd disk go to the Caravan at night and talk to Raul the hunter repeatedly. Eventually he will give you the vernato pipe/flute. Next, go to the Village of Zoah during the day and talk to Jeal in the bar (use the back entrance because the front entrance is closed during the day). Give the vernato pipe to Jeal and as a reward she will ask Juba to give you free advice and drinks. Return to the Caravan and talk to Raul again. He will give you 1000dn for the trouble.

The 1st time you enter the Village of Zoah talk to the man who lives to the right of the sewer entrance in the 2nd section of the Liberal District. Look at his gun and he will start a conversation about being a hunter. Talk to him again a couple times and he will give you a little hunter's quiz. If you answer all of his hunting question correctly he will give you the mauler gun part which increses your gun's power by 30+.
