Cautus Valley Mining Area
During the event, the player will receive one mining operation every day, which can be used to receive Orundum from three different types of Originium deposits in Cautus Valley Mining Area, selected at random in each use:
Deposit | Value |
---|---|
Originium Crude Ore | 300 ![]() |
Originium Ore | 400 ~ 1700 ![]() |
Originium Vein | 1800 ![]() |
- The amount of Orundum received will only be shown after the mining operation is completed.
- If the mining operation does not reach an Originium Vein, the next mining operation(s) are more likely to reach it. If an Originium Vein was not reached by the end of the event, then the last mining operation is guaranteed to reach an Originium Vein.
- Unused mining operations do not transfer over to the next day, so they must be used before the daily reset.

Trivia
- The Chinese title is a pun to the first part of this Chinese proverb 覆巢之下无完卵 (lit. "no eggs remain intact when the nest overturns") which means "no individual can escape from the calamity its group is suffering,"[1] with a slight change of a homophonic character from 巢 ("nest") to 潮 ("tide").
- Under Tides operations are prefixed with "SV", which stands for "Sal Viento" (where the event's plot takes place). However, Children of Ursus operations are also prefixed with "SV", which stands for "Survivor" and can lead to confusion for SV-1 to SV-7.
- This is the first and only case of an event's operation prefixes overlapping with another's.
