地域のアンロック方法（進行）

沈黙のベールは最初から開いています。地域がクリアされると、ゲームはそれにリンクされている地域を開きます（OpenAdjacentRegion）。リンクはコード内で固定されています（SetAdjacency).

リンクは:

• Clearing Veil of Silence opens Festering Burrow.
• Clearing Festering Burrow opens Abandoned Mine and the Infinite Abyss.
• Clearing Abandoned Mine opens nothing.
• Clearing Forgotten Abyss opens Dead Swamp, and clearing Dead Swamp opens Forgotten Abyss.

No clear opens Tower of Apocalypse, and no clear of the first three regions opens Forgotten Abyss or Dead Swamp.

Only the first 2 regions have real content; the rest are placeholders (see the 制限コンテンツ ページ）。

各地域は クリアボス を定数 GAMESYSTEM_Dungeon_UnitForClearRegion. In the current data 2 slots are filled:

• 枠 0、沈黙のヴェール のクリアボスは 巨石ゴーレム
• 枠 1、ただれた巣穴 のクリアボスは チェインナイト・センティネル

2 of the 8 slots are filled; every later slot is NULL.

The chain, traced in the DS_B.0.4.11 binary (2026-09-04):

• Every campaign region has 5 floors (GAMESYSTEM_Dungeon_MaxFloor). Floor n runs dungeon phase PhaseUnit[n] from GAMESYSTEM_Dungeon_PhaseUnit = [0, 1, 2, 3, 4, 5] (index 0 is the safe floor), so floor 5 runs phase 5.
• Phase 5 is the boss phase: its room pool is Entry -> Boss -> Portal, and the boss room (DUNGEONROOM_VeilSilence_Boss_GiantStoneGolem, AvailablePhases = [5]) generates there. Festering Burrow's floor 5 generates DUNGEONROOM_FesteringBurrow_Boss_ChainKnightSentinel the same way.
• Killing the clear boss on that floor flags the region's boss as defeated (TryMarkCurrentRegionBossDefeated). The expedition result screen then offers Return; pressing it commits the transition and marks the region cleared (SetClearRegion -> SetDungeonClear -> SetRegionClear) and opens the neighbour (OpenAdjacentRegion).
• On the boss floor the exit portal is already the next region's portal (BUILDING_DungeonFloorPortal2 on Veil of Silence, BUILDING_DungeonFloorPortal3 on Festering Burrow).

"The Golem cannot spawn." Earlier versions said Veil of Silence's own phase table, GAMESYSTEM_Dungeon_Floor_Phase_Division_Veil_Silence, caps the region below the boss phase, so the boss room could never generate.

That table exists in the data, and no build since B.0.3.40 reads it. A search of the game binary's string literals finds zero references in B.0.3.40, B.0.3.44 and DS_B.0.4.11. The floor's phase comes from GAMESYSTEM_Dungeon_PhaseUnit, as above. The boss floor was reachable all along.

"A second lock keeps Festering Burrow closed." Earlier versions also described hardcoded Festering Burrow exceptions in the binary. Those instructions existed in B.0.3.14 and are gone from B.0.3.40 onward:

• IsRegionBlocked returns false for every region
• SanitizeRequestedRegion returns its input unchanged
• Neither OpenAdjacentRegion nor GetAvailableRegion tests the region number

In the demo and playtest builds (B.0.3.x) the game also auto-completed Veil of Silence. A demo-only resolver marked the region cleared from floor 5's result screen, boss kill or not.

DS_B.0.4.11 removed that behaviour. The resolver is compiled to a constant false, and the result screen reads the real boss-defeated flag.

メインストーリーのクリアは、地域のクリアとは別の軸だ。 這い寄る破滅 main chain (メインクエスト 0 から メインクエスト 8) ends with killing the 赤いモンスターネズミ, an elite monster, not the region's clear boss.

Completing it finishes the scenario's story but does not clear Veil of Silence and does not unlock Festering Burrow. See クエスト.

Some earlier builds re-derived the unlock from IsCleared on every load. On those builds IsLocked edits did nothing. See セーブファイル.
