The objective in this mission is to defeat the boss. The map is separated by floating islands and aside from fliers, your ground units need to utilize the sigils to teleport from one point to the other. You can see where a sigil leads to by selecting the sigil. Remember that you can only travel to unoccupied sigils. If an enemy or allied unit is standing on the other side of the sigil, you won’t be able to use them. Have a good balance of strong ground units and fliers since there are a considerable number of bow-wielders here as well.
Also, the large fort where the boss is located can only be accessed by activating a central sigil underneath the giant statue in the starting area. You have to break the statue by activating all eight dragon veins in the area. Each of these dragon veins are located inside the smaller forts and protected by enemy units. In order to free these dragon veins more effectively, you’ll really have to divide your forces, preferably in groups with royal family members who can activate the dragon veins. Concentrate on strategically placing your units and thinning out the enemy numbers. There are treasure chests to look after in this map but there are several enemies carrying green items that can be dropped upon their defeat.
Enemy units will appear on unoccupied/unactivated dragon veins around the 6th turn onward. After activating all dragon veins, the central vein will be revealed and you can use it to teleport inside the base where the boss and the last three enemy units are waiting. Make sure to regroup and heal first before using the central sigil to reach the boss. The boss is pushover herself so extra preparations are necessary.
Note: The specific character’s death in this chapter is permanent and there’s nothing you can do to prevent it since it is part of the story.
