This location becomes accessible at Chapter 5. This location has a lot of good loot but most are hidden behind obstacles that will require a fair amount of over-damage. During your first visit, some of the exits will be blocked by guards but you can still fully explore the area. There are also several upgrade materials that you’ll need to get from here as well as other Requests
so fully exploring the island is recommended. Please refer to the map below to find all treasure chests and Delicious Candies on the mountain.
As for the obstacle in the northwest that requires 100,000 Over Damage
to destroy, follow these steps:
1. Have a full Fairy Gauge ready.
2. Head to the obstacle's location and save.
3. Activate Link Hunt
and quickly accept it so you'll only link 2-3 monsters.
4. Activate Wendy
's Arms Buff
5. Use a Magic Chain
and complete the full combo.
Successfully destroying the obstacle will yield a Sparkling Candy
