Forest Entrance
You will begin the mission in here. In this area you find a number of egg sacs for orb farming. Also you will locate Secret Mission 5 here (it is hidden inside the mini-grave house beside the tree trunk). Orb statue is also here, so you should be able to maximize your orbs if you want to complete the Vitality and Devil Trigger Gauge. Simply head straight to the path between the rocky mountains.
Windswept Valley
You can find Holy Water by jumping along the northern edge of the map. Simply head straight down. Here you will find a new breed of lesser-demon, the Chimera. Chimeras are weak to buster, yet if left unattended, can prove deadly. Kill them as fast as you can. Head through the stairs and enter through the church.
