Chapter 2 sees Class Zero deployed to the Rubrum region to defend against a renewed Milites offensive. This chapter introduces more complex mission structures and environmental hazards. You'll also have more freedom to explore Akademeia between missions and undertake side quests.
Pay attention to mission briefings, as they often contain vital information about enemy types and environmental conditions. Consider bringing cadets with specific elemental magic if the mission intel suggests it. This chapter also introduces the World Map, allowing for strategic movement between locations.
