The Long Ear Invitation puzzle in the Delver of the Cryptic event for Arknights: Endfield offers a blend of challenge and enjoyment. The primary objective is simple: follow one specific long-ear to the exit. However, players aiming for completion must also locate six long-ears scattered throughout the puzzle before making their escape.

To earn all the rewards associated with the Long Ear Invitation stage, players must not only finish the main puzzle but also meet the bonus goal of identifying all six long-ears and leading them back to their hideout. At the beginning of the stage, three long-ears can be found, but players need to stay alert as some will scatter throughout the area only to reappear later.

Among them, one long-ear will reach their hideout before the player, marking their first successful rescue. Players should continue to follow the remaining long-ears, particularly the one that leads to a hidden space behind a breakable wall. Utilizing explosive barrels located within the stage will be crucial to access various sections and unlock further rooms.

As players navigate through the labyrinth, the long-ears will engage in a pattern of scattering and rejoining, and it’s vital to track their movements closely. Following the right path will lead to hidden spots where additional long-ears await, often behind barriers that require strategic action to access.

The journey through this puzzle intricately combines observation, strategy, and the occasional explosive action, ensuring that players remain engaged. Each captured long-ear brings them closer to fulfilling the stage’s requirements, highlighting the game’s balance of exploration and goal achievement.

In summary, the Long Ear Invitation puzzle challenges players to adeptly traverse its intricate paths, successfully capturing all long-ears while unlocking secrets within Arknights: Endfield. With patience and keen observation, completing the stage and reuniting the long-ears becomes an achievable feat.
