Cecilia Garden rotates the rewards you get based on what day of the week it is.
On Tuesdays and Fridays, the domain is called Submerged Valley, and you can get the Boreal Wolf's Cracked Tooth Weapon Ascension Material, and all previous rewards.
On Sunday, you can choose whatever domain you desire.
To complete Submerged Valley II, you must kill all 23 enemies. But the time between kills cannot exceed 25 seconds.
- The 23 enemies to eliminate:
- Hydro Slime x12
- Large Hydro Slime x3
- Wooden Shield Hilichurl Guard x8
Due to the Hydro enemies, it is wise to bring along characters that inflict Cryo, Pyro, and Electro Damage.
