Field note 01Yggdrasil LabyrinthEight Strata · Final cap Lv.75
Before you descend
Know how the cap works.
The developer’s v4.1.1 reference lists one cap for each Stratum. Normal and Hard Mode enforce level caps; Picnic Mode removes them. Healing items remain unavailable during battle in all three modes.

Spoiler-light roadmap
Eight Strata. Four story parts.
Names and caps come directly from the developer’s v4.1.1 sheet. Open a row for the named Hard Mode encounter when the sheet identifies one.
Stratum 2 naming note. The dedicated v4.1.1 sheet says “Sand Sea of Golgonda”; the developer’s Hard Mode boss tab and an earlier in-game screen use “Desert of Golgonda.” This guide follows the purpose-built Level Caps tab and records the discrepancy rather than hiding it.
While exploring
Read the Labyrinth’s signals.
01
F.O.E.s
Powerful Pokémon appear on the field as visible encounters. The developer lists F.O.E.s as a core exploration system.
02
Gathering and mining
Spend 1, 5, or 10 stamina at resource points. The developer describes 1 for variety, 10 for quantity, and 5 as the middle option.
03
Chests
Opened chests remain visible to help mark explored ground. Red chests hold items or money; yellow chests hold TMs.
This focused list covers quests that open islands, improve the shop, or award progression tools. It does not duplicate the complete sidequest spreadsheet.

The developer’s v4.1.1 workbook includes a separate postgame boss roster and an Abyssal God guide. The exact story outcome is kept behind the spoiler control below.
Spoiler vaultReveal the verified final postgame trigger
The developer guide identifies the Abyssal God as the final postgame boss and the last obstacle before the true ending.
Use the geomagnetic pole at the base of Yggdrasil to reach Claret Hollows.
Reach the deepest part of the Labyrinth and find the sealed boss-room door.
Defeat at least one of the eight tentacles scattered through the map to unlock the door.
The boss team changes according to how many tentacles have been defeated. This guide does not reproduce the full team tables.
What this guide can prove
Progression help without guesswork.
The available developer references verify order, names, caps, selected boss labels, quest records, and the postgame trigger above. They do not provide a complete written route through every floor.
