How to Participate
You can participate in the Sunken Depth Defense Event through the Sunken Depths Memory in Seria’s room or by clicking the HUD icon() above the fatigue bar.
Protect the barrier gauge while defeating the Memories of the White Ocean! The Sunken Depth Defense will end if the barrier gauge reaches 0% after playing for 2 minutes or if you complete all 40 rounds.
Daily rewards accumulate based on your playtime and completing accumulated missions increases both max obtainable amount of Daily Rewards and amount of rewards obtained per time.
Complete your daily/weekly missions and exchange the Sunken Depth Defense Tokens for useful items in the event shop. You can also earn additional rewards through the Achievement Progress in the Sunken Depth Defense Stats!
