In Endor, you can visit the casino. While not mandatory for the story, it's a good place to earn some extra gold or even valuable items if you're lucky. Your main objective is to find Balzack's Mansion. You'll learn that it's located to the north of Endor. The mansion is a dungeon filled with tougher enemies, including Man O' War and Rogue Nite. Maya's 'Frizz' and 'Sizz' spells will be very effective here.
Recommended Level: Maya 12-13, Meena 11-12. Navigate the mansion, collecting treasure chests. You'll eventually confront Balzack. He is a challenging boss. Have Maya use her strongest offensive spells, and Meena focus on healing with 'Heal' and potentially using 'Sap' to lower Balzack's defense. After defeating Balzack, you'll uncover more of the truth about their father's death, but the true mastermind remains elusive. This concludes Chapter 4, setting the stage for the grand union in Chapter 5.
