Exploring Sumatra Continent was his lifelong dream. And the farther he was forced to stray from this path, the greater it became his obsession. Originally, the Zinger build was perfect for his dream.
With enough planning, schemes, and appropriate execution, Inala was confident in killing the Empyrean Boar King during the Fourth Major Disaster. That was the intended outcome. However, with seven cooks stirring the plot, things were messed up beyond control.
Some of the faults lay with him too, and Inala was aware of them. However, the situation forced his hand to make such a choice. Otherwise, he wouldn't have managed to survive or grow to his endgame build.
