Close to the Frontier settlement of Saoki, the caverns are home to many monsters, who ravage the nearby villages. At various depths in the cavern are fixed groups of monsters you can fight to liberate Saoki from their terror.
- B1 - War Beast x2
- B2 - Greater Zombies x5
- B3 - Butterfly x3
You can bypass the first 2 fights and just focus on the main boss (the Butterflies on B3) if you just want to free Saoki, however in killing all 3 sets of monsters you can prevent Jewel Beast's awakening for a short period.
- Find Chests
- Disarm Traps
- Find Ore
- Defeating all the sets of fixed-fight monsters will delay the rampage of Jewel Beast
