The Prison Island was an island which had training zones that were substantially better than the Main Island, Desert Island and Lost Sea Island. However, SS class was required to access the island and at least 10 Sp for the Strength, Endurance or Psychic stats respectively to train there.
An NPC clothed as a prison inmate was present inside the cell building (where the portal is located), which sold boosts for tokens (Boost Shop), limited to 5 for each boost each day (reset time at 00:00 UTC).
