| Starter Island -> Snow | Early linear progression through beginner and lower-mid content | Best used for core leveling rhythm, quest familiarity, and early setup |
| Shibuya | Mid progression map with rising system and material value | More than just a level gate, it starts feeding broader progression systems |
| Hueco Mundo | Higher-value mid progression island | Important because later systems and collection routes increasingly overlap with these maps |
| Sailor Island | Strong farming island with multiple boss-related loops | One of the most commonly highlighted islands for efficient farming |
| Shinjuku | Transition into stronger system-heavy progression | Pushes players toward more structured farming and tougher content |
| Boss Island | Boss-centric route for drops, tickets, and progression materials | Important because many mid-to-late upgrades depend on boss farming |
| Slime Island | Home of the Skill Tree NPC | Critical growth island because it unlocks a major permanent damage system |
| Dungeon Island | Dungeon system entry point with extra unlock conditions | Not just a leveling map, but a system gateway with its own requirements |
| Academy Island | Late-game quest zone around the 10,000 to 10,750 range | Signals that you are close to the current endgame route |
| Judgement Island | High-end late-game quest area around 10,750 to 11,500 | One of the most important newer progression regions in the current version |
| Soul Society | Late-game region gated by the Hogyoku quest and fragment order | Cannot be treated as a simple level gate because system progression matters first |
