Metal Sea Overview

Unlocks at Stage 150

The Metal Sea in Digimon UP unlocks after challenging Stage 150 and once three days have passed since the server launched. Progress through the stages to meet the stage requirement, then access the Metal Sea once the three-day requirement has been met.

Attempt Count Resets Daily at 15:00

Entering the Metal Sea requires a 'Digital Gate: Green', which replenishes up to a maximum of 2 each day at 15:00. Be sure to use any remaining entries before the daily reset to avoid wasting them.
