The release records no separate place for this step: its task page files the area the step opens, and a page the step opens is not a place the step happens in.
The release records no separate condition for this step: its task page files the cell that follows it, so nothing is printed here as something to satisfy first.
Task: Deeper Research
Stuck on this step?
This step’s task page also offers “I can’t find …” for the item the step hands over and “I can’t reach …” for the area it opens. Neither is a reason this step is stuck, so neither is repeated here.
Main Tasks
- Deeper Research
This stage is one recorded step of this task.

Optional & Parallel Content
Parallel content can be developed alongside this stage’s route; optional content is not confirmed as required. The record decides which is which, and the two are never mixed into the numbered step above.
Parallel
The record marks no parallel path on this stage — everything recorded here is on the main route.
The record marks no parallel path on this stage — everything recorded here is on the main route.
Optional
The record marks nothing on this stage as optional, so nothing here is offered as a can-skip extra.
Stuck in This Stage?
A required item is missing
The finder answers where each item comes from, so a missing key or rope can be sourced rather than guessed at.
The task this stage belongs to is not appearing
The task guide carries the release’s own recorded conditions, including the ones nobody expects to matter.
You are not sure which step you are on
The assistant asks what you have finished and answers with the next recorded step.
You lost an item you already had
Item pages record where each one comes from, so the item can be checked against its own source rather than an inventory guess.
