Booster Pack Heroes Hall of Holos: Foil Collection

What does Hall of Holos actually require?

The requirement covers foil heroes and foil tomes. Finding ordinary versions, finishing chapters, or buying upgrades does not by itself demonstrate that you have completed those foil discoveries. The reviewed achievement notes specifically identify tomes as something players can overlook when assessing their collection.

This guide covers the retail Steam game, which launched on November 10, 2026, and the available evidence available on November 11. The official Steam listing identifies the retail release; patch-specific findings below come from the developer’s published notes.

Collection check	What the evidence establishes	What to verify
Foil heroes	Every foil hero belongs to the requirement	Check hero discoveries individually
Foil tomes	Every foil tome also belongs to the requirement	Review tomes separately from heroes
Ordinary discoveries	Owning the ordinary version does not establish foil discovery	Confirm which version you actually found
Bright or unusual artwork	Appearance can lead to mistaken assumptions	Confirm foil discovery beyond visual contrast

A useful hall of holos checklist therefore records heroes and tomes separately. The available evidence does not provide a complete named checklist or a verified total of required foil entries, so an exact completion count would be speculative.

Audit heroes and tomes before opening more packs

Start your hall of holos check by identifying what you can actually confirm. A collection that looks finished at a glance can still contain an ordinary tome you have mistaken for its foil version.

The reviewed discussion notes include a developer asking a player whether they also had every foil tome. They also describe a player experience involving confusion over the Frozen Tome’s contrast. That example supports a practical recommendation: treat brightness as a reason to inspect an entry more closely, rather than sufficient evidence of foil discovery.

Work through the audit in this order:

1. Review heroes individually. Record which foil discoveries you can confirm.
2. Make a separate tome list. Give tomes the same attention as heroes.
3. Flag uncertain entries. If you cannot establish whether a variant is foil, keep it unresolved.
4. Compare discoveries with the achievement status. Record whether the achievement remains locked after your review.

These are source-based troubleshooting recommendations, not a developer-published sequence that guarantees an unlock.

What you find	What it suggests	Useful next action
A hero without confirmed foil discovery	A possible collection gap	Investigate that hero’s available pack pool
A tome without confirmed foil discovery	A possible collection gap	Focus your check on that tome
An entry judged only by brightness	Discovery status remains uncertain	Recheck the evidence for its foil version
Every required foil appears confirmed	A tracking issue becomes more plausible	Check the installed patch and document the collection

Keep your notes specific. “Every hero seems shiny” provides less useful information than a list showing which heroes and tomes you checked. Likewise, completing a skill tree answers a different question from discovering every foil variant.

If a tome remains uncertain, focus on resolving that uncertainty first. You do not yet have enough evidence to classify the problem as an achievement bug. If every required discovery is confirmed, your next step is version checking and a clear report rather than assuming another random pack will solve it.

Choose packs around confirmed collection gaps

The official game description says booster packs have their own pools of heroes and spells. It also explains that defeating chapter bosses unlocks additional packs and collection options. Those facts support targeting an identified gap through the relevant available pack pool. They do not establish a universal fastest farming route. See the official pack and progression description.

For a hall of holos cleanup session, begin with a missing discovery you can name. Then use the game’s available information to determine which pack can supply it. This gives your pack opening a clear purpose without relying on an unsupported claim about the best pack.

The supplied material does not establish:

• Exact foil drop rates.
• A guaranteed number of packs before a missing foil appears.
• A pity counter or a method for resetting one.
• A specific upgrade purchase order for completing this achievement.

Those gaps matter when evaluating farming advice. A strategy that sounds efficient may depend on probabilities or interactions absent from the evidence.

The official launch announcement lists 10 booster packs and 40 pullable units in the full game. Those figures describe the broader release. They do not supply a verified breakdown of every hero and tome counted by Hall of Holos.

Older player experience on the official itch.io page includes difficulty finding a foil Raise Dead tome in the demo. That illustrates why a tome deserves a separate checklist entry. It does not establish a retail drop rate, expected completion time, or guaranteed farming method. The context remains the official itch.io demo discussion.

Official gameplay video

The launch trailer by Funday Games shows the game’s general pack-opening and tower-defense loop. It is a gameplay overview, rather than a demonstration of this guide’s specific objective.

What patch 1.0.30D confirms about achievement problems

If hall of holos remains locked after your collection audit, check whether your installed game includes patch 1.0.30D. The developer reports fixing some achievements that previously could not unlock, but the published notes do not identify each affected achievement by name.

That distinction limits what the patch can prove. It establishes that achievement fixes were shipped. It does not establish that Hall of Holos now works for every affected save or explain whether previously completed requirements are checked automatically. The relevant source is the official patch 1.0.30D announcement.

Published patch change	Relevance to your investigation	Remaining uncertainty
Some achievement unlock problems were fixed	Updating is a sensible troubleshooting step	Hall of Holos is not specifically named
Acts 1 and 2 can continue after completion, with quests progressing	Earlier acts offer additional play after their endings	No guaranteed Hall of Holos completion route is described
Some tome reveal descriptions were corrected	Tome information received fixes	This does not establish a changed foil drop rate
The Spider Queen’s foil small spider became easier to find	A specific foil discovery received an adjustment	Its inclusion in Hall of Holos is not established

The small spider change deserves particular care. It is a confirmed patch improvement, but the available evidence does not show that this enemy discovery is part of the achievement’s hero-and-tome requirement. A separate foil collection problem should not become an extra requirement without evidence.

Community reports on the Steam Community hub include players saying Hall of Holos stayed locked despite apparent completion. Reviewed notes also describe mixed reports around the fixes. These accounts support investigating a possible tracking issue, but individual reports do not establish identical conditions across all saves and builds.

If your achievement remains locked, prepare a report with your installed version, confirmed hero discoveries, confirmed tome discoveries, and any uncertain entries. Mention whether completion occurred before or after updating. This information helps distinguish a missing variant from a trigger problem without claiming a guaranteed repair.

Keep retail, demo, and mobile evidence separate

Version context matters because the supplied sources cover several editions and different update histories. An observation from one edition should retain that label when you use it to assess achievement advice.

Evidence source	Confirmed context	Appropriate use
Retail Steam listing	Full game released November 10, 2026	Establish the retail Steam scope
Steam demo listing	Separate demo released April 30, 2026	Identify demo-specific observations
Official App Store listing	Supplied listing shows version 1.0.16	Keep Apple release evidence distinct from Steam patch evidence
Official Google Play listing	Supplied listing records an update on November 10, 2026	Establish the Android listing’s own update context

The developer’s Next Fest demo announcement describes Interlopers as rare pulls that could introduce heroes from full-game packs into the demo. That announcement explains a demo feature; it does not establish a retail Hall of Holos strategy or prove that demo discoveries satisfy the retail achievement.

A useful hall of holos report should identify the edition and installed version alongside the collection details. The Steam patch number alone cannot establish which fixes another storefront’s build contains.

For your next session, choose the action your evidence supports: resolve an uncertain foil, pursue a confirmed missing discovery, or document a probable achievement issue after checking the patch.

FAQ

Why hasn’t hall of holos unlocked after I found every hero?

The requirement also includes every foil tome. Review tomes separately, and confirm foil discovery rather than ordinary ownership or bright artwork. If both groups are complete, check your installed version and document the problem. Launch-period community reports describe apparent completion without an unlock, so a tracking issue remains possible.

Does patch 1.0.30D definitely fix Hall of Holos?

The official notes confirm fixes for some achievements, but they do not specifically name Hall of Holos. Updating is supported advice; promising an unlock for every existing save is not. The available evidence also does not establish a reliable action that forces the achievement to recheck completed discoveries.

Does the foil small spider count toward Hall of Holos?

Its inclusion is unconfirmed in the available evidence. Patch 1.0.30D makes the Spider Queen’s foil small spider easier to discover, while the stated achievement requirement concerns foil heroes and tomes. Keep the spider patch change separate unless additional evidence establishes its relevance.

What is the fastest verified way to finish the achievement?

No fastest route is established. The most useful supported approach is to audit heroes and tomes, identify a specific missing foil, and investigate its relevant pack pool. If every required discovery is confirmed, check the patch and submit a detailed report instead of relying on an unverified farming trick.
