Ocean Area Survey Quests



Ocean Area Survey Quests (海域調査), also referred to as "lettered quests," are one-time completion quests that ultimately unlock the True Ocean Area Quests. These quests do not have farmable drops, but each world has 3 rewards when obtaining 10/20/30 stars.

See List of Enemies for details on enemy types and enemy colored buffs.

General strategies for clearing:

Enemies do not have to be sunk in order.

Prioritize enemies that will eventually move out of range, or use carriers.

Ships that can inflict the Inhibit status can stop healing enemies from healing.
