Colliery Underground Second Floor

Enemies:  2 thieves, 1 behemoth, 1 king behemoth, 1 chemist        Guests:  Beowulf

Orlandu will take care of the behemoths easily, also the theives are easy to kill. Save the chemist for last, he has a Blaze Gun, ( The gun Balk had, if you didn't steal it from him ) make sure to steal it, it's a great weapon for Mustadio. Once you succeed in stealing the gun, finish him off.
