Sword x Staff: Secret Treasure Operation Energy Guide

In Sword x Staff, optimize your energy during the Secret Treasure Operation event by prioritizing exit keys and advancing immediately rather than uncovering every tile on a floor. Because each revealed square consumes a fixed amount of energy and overall free stamina is limited, spending moves on peripheral tiles drains the reserves required to reach deeper levels containing high-value milestone rewards.

Board Clearing Strategy: Key Sniping vs. Full Clears

Every exploration grid hides passage keys alongside minor consumables. How you handle these boards determines how deep you can climb before the event ends.

• Key Sniping: Once you reveal the stage gate key or objective item, unlock the passage and advance immediately. Leaving unrevealed tiles behind saves substantial stamina across multiple floors, allowing you to hit advanced reward checkpoints on free energy.
• Full Board Clearing: Clear an entire floor only if it is explicitly designated as a guaranteed bonus room or contains confirmed high-tier treasure chests uncovered through early clues.

To minimize energy spent per floor, check high-probability central tiles or follow diagonal paths rather than clearing row by row. Avoid the sunk cost trap: uncovering several empty tiles before finding an exit does not justify spending additional energy to clear the rest of the board. Advancing through the gate permanently seals the current level, so leave standard crafting materials and minor consumables behind without hesitation.

Stamina Budgeting and Milestone Calculations

Secret Treasure Operation awards its primary prizes at fixed floor thresholds. Before committing energy, compare your projected total stamina against the remaining event schedule to ensure you can reach a designated milestone.

If your calculations show that your total energy will fall short of the next major reward tier before the event concludes, stop aggressive clearing on intermediate floors. Pushing partway toward a tier yields diminishing returns and leaves your account stranded between prize ranks.

When to Purchase Energy Bundles

If you aim for competitive rankings or specific high-tier milestone rewards, free energy alone may not cover the full distance.

Apply one strict rule when spending premium currency or buying limited-time shop packs: purchase additional stamina bundles only if the added energy guarantees reaching a specific, high-value milestone that justifies the expense. Buying partial energy packages that merely advance you across an intermediate, unrewarding floor wastes resources without providing a tangible progression boost. Calculate the total cost required to reach the target tier, confirm you have sufficient time remaining in the event schedule to explore the boards, and execute your purchases in a single coordinated run.
