After retrieving all six Deeplake Relics from doing UMV dives in the POLUT Underwater Mining Lab, Cephalops was found inside the Deeplake Tomb as a Set Encounter. After the battle ends, the game will show the statistics page of the caught Cephalops if applicable and allow the player to rollback their progress if the result is not satisfactory, restoring all items used in the battle and returning the player's Loomians to the state they were in before the battle, thus giving the player another chance to catch Cephalops. This also applies when the player runs from the battle. Once the player decides that they are satisfied with the results of the battle, Cephalops will no longer be available as a Set Encounter and will instead roam with an extremely scarce chance to be encountered in the wild.
