Walkthrough
The final boss has all 3 different life bars. Shield, Armor, and a Health bar. When buying and selling your gear before the fight you want to consider this and keep a few elemental weapons that are strong against these different life bars.
The final boss will be riding a beast during his Shield and Armor phase. His pet will be defeated once you make your way through these life bars.
During his health bar, the boss will keep calling additional forces to make your life a nightmare. Throughout the fight, there will always be a minor enemy to get a second wind on.
Notes
- If you get a good Tediore weapon in the started chest, you can (easily) defeat the boss with it.
