Track what is missing and what is finished
The Collection Book area helps you keep a clear line between missing items and collected ones. That becomes more useful when it feeds back into Mission Alerts, because the alert list can show whether a reward still matters before you run it.
Built-in database across item types
The tracker includes an in-app reference database for key STW Collection Book categories. That includes weapons, traps, heroes, survivors, lead survivors, defenders, and related item groups needed to identify rewards and collection targets more reliably.
Viewer and grid workflows
StormBook supports different ways to review Collection Book progress, including a visual in-game-style viewer and a more direct grid/list style. That lets you browse the collection the way you prefer while still working from the same stored progress data.
Why it helps day to day
Without a tracker, it is easy to lose track of whether a reward belongs to a hero, survivor, lead survivor, or weapon line you still need. With the Collection Book data already in the app, StormBook can help you make that decision faster when alerts reset and when tasks are completed.
The Collection Book is not isolated. It is part of the same workflow as alerts and tasks, which is the main reason the tracker stays useful across resets.
