## Notes

**Impel Down** is the Intermediate-to-Advanced difficulty map, themed after the underwater prison from One Piece. Its lava traversal sections demand more careful movement than Shibuya's open layout.

**Title tie-in**: 30 Impel Down clears unlock the **Fleet Admiral** title (+18% DMG, +40 HP, +10% EXP). See the tier list for the full title cluster.
