Doomsday: Odysseus Returns Base Search Event Strategy

To maximize milestone points and exchange tokens in the Doomsday: Odysseus Returns Base Search event, rush directly through early levels and save your exploration energy for deeper floors. Locate the access key, unlock the exit terminal, and descend immediately on Floors 1 through 10. Once you reach Floor 11 and beyond, transition to clearing high-value supply tiles before exiting.

Grid Pathing and Tile Priorities

Each floor is covered in fog on a grid layout. Revealing a tile consumes a fixed number of search tokens, and you can only uncover tiles adjacent to previously cleared spaces.

Path straight toward the center of the grid rather than tracing the outer borders. A central line exposes more adjacent tiles per step, giving you greater visibility across the board with fewer consumed actions.

Prioritize tiles based on their impact on progression:

Hostile sentries block movement until defeated through combat or combat items. Engaging sentries on low-tier floors expends stamina for minimal point returns. Unless a sentry directly obstructs a passage or shields an access key, bypass it.

When to Rush vs. When to Clear

The point-to-energy ratio scales significantly as you descend, making full clearances on early floors inefficient.

Floors 1 to 10: Early Rushing

Adopt a strict rush strategy for the first ten floors:

1. Reveal central tiles until you find the floor's access key or security card.
2. Move directly to the exit terminal once unlocked.
3. Descend immediately without uncovering remaining supply crates or clearing defeated sentries.

This conserves your starting stamina and quest batteries for sectors where reward multipliers are much higher.

Floor 11 and Beyond: Selective Clearing

Reward quality and milestone points increase noticeably in deeper tiers. When entering Floor 11 and higher:

1. Locate the access key first to secure your route to the next floor.
2. Survey the remaining fog and reveal high-value targets, including vision terminals, elite supply drops, and rare gear materials.
3. Take the exit once high-value tiles are cleared or when search tokens drop below what is required to reach the next floor's exit.

Stamina and Shop Currency Management

Event stamina regenerates automatically on a fixed timer. Extra search batteries come from daily active quests, alliance assistance, and limited gem purchases.

• Prevent stamina capping: Spend your regenerating stamina throughout the day so the timer never pauses at maximum capacity.
• Time gem purchases: Hold off on buying search batteries with gems until the final day of the event. At that point, calculate your total depth to determine whether extra batteries will push you across a specific milestone reward threshold, such as legendary hero fragments or armament chests.
• Exchange Shop priorities: Spend accumulated event tokens on exclusive armament components and universal legendary hero badges. Avoid buying basic speedups, stamina packs, food, or wood crates, as these can be gathered freely during routine gameplay.
