Booster Pack Heroes Achievement Guide: Unlocks & Fixes

What should you check before chasing achievements?

This guide covers the retail Steam game released November 10, 2026, using evidence collected November 11. The official Steam listing identifies the full game; the separate Steam demo listing identifies the demo. Demo observations are labeled below.

Start by checking whether you are running patch 1.0.30D. Its official notes confirm fixes for several achievement triggers and a missing final relic-pack quest reward. They also introduce continued quest progress after finishing Acts 1 and 2. Those changes directly affect achievement cleanup. See the official patch 1.0.30D announcement.

The available evidence supports a focused roadmap and troubleshooting guide. It does not provide a complete official achievement list, every spending threshold, or all hidden conditions. Early milestone names below come from achievement-index excerpts; requirements associated with collection problems are clearly labeled as community reports.

Before another farming session, write down three things: the locked achievement, your current collection or quest progress, and your game version. That gives you a specific target and makes any remaining bug easier to explain.

Track pack milestones and collection discoveries separately

A useful achievement guide separates repeated actions from unique discoveries. Opening more packs can advance an opening milestone, while a collection requirement depends on discovering the missing entry.

Available achievement-index excerpts identify these early targets. Their full pages were inaccessible, so confirm the wording in your Steam achievement panel.

Reported achievement	Requirement shown in the excerpt	What to check
Fresh Packs	Open 10 packs	Whether the opening milestone has registered
A lot of packs	Open 100 packs	Pack-opening progress rather than collection size
Out of Place	Discover an interloper	Whether an interloper discovery has registered
Shiny!	Discover a foil hero	Whether you have discovered a foil hero

The distinction matters when choosing your next action. If your objective involves pack openings, inspect that milestone. If it involves discovery, identify what remains undiscovered before choosing packs. The official description confirms that different booster packs have different pools of heroes and spells, and chapter bosses unlock additional content. That supports matching purchases to the collection gap you are trying to fill. See the official game description.

Keep spending requirements separate as well. The supplied excerpts mention Bag of Coins, but do not include its condition. Its name alone cannot establish a required amount, whether it counts spending or earnings, or whether progress must happen within one run.

Treat interloper advice from the demo carefully

The developer’s Next Fest announcement describes interlopers as unusually rare heroes that could appear when opening any pack in the demo. Those heroes came from pack pools associated with the full game. The announcement supplies no numerical drop rate.

That is demo-specific evidence. It does not establish retail odds, a guaranteed farming method, or a required number of openings. Use the official demo update to understand the feature’s documented demo behavior.

Resolve relic, foil, and bestiary gaps

This achievement guide treats a missing discovery and an achievement that fails to register as separate problems. First inspect the relevant collection; then compare its state with the locked achievement.

Community reports associate the following names with collection completion. These are reported requirements, rather than independently verified official descriptions.

Achievement named in community reports	Reported requirement or collection state	Useful next check
Museum Curator	Discover every relic	Compare the relic collection with the locked achievement
Hall of Holos	Discover every foil hero and tome	Inspect heroes and tomes separately
Prismatic Bestiary	A player reported a fully unlocked foil bestiary	Check the bestiary and record your version

Players reported Museum Curator and Hall of Holos remaining locked despite apparently completed collections on the Steam community hub. These reports establish that players encountered problems; they do not prove that every similar case has the same cause.

Museum Curator: check the patch before replacing relics

One player reported 39/39 relics with the achievement still locked. Developer Jordy replied that players on an older version should restart to obtain 1.0.30D, and that a continuing problem on that version would need investigation. That is the most specific developer response available for this issue. See the relic achievement discussion and developer reply.

The launch announcement advertises 40 relics, while that player reported a 39/39 collection display. The evidence does not explain the discrepancy. Record the number your game shows rather than assuming either number proves what your save lacks.

Another player questioned whether destroyed relics had to be reacquired. That remains an unanswered player experience, not a confirmed ownership requirement. There is no supported basis here for recommending that you replace every destroyed relic. See the community question about previously discovered relics.

Foil Small Spider: a documented improvement, without exact odds

Patch 1.0.30D makes the foil Small Spider spawned by the Spider Queen easier to find. It does not publish a drop percentage, guaranteed encounter count, or complete acquisition procedure.

A separate community report describes Prismatic Bestiary staying locked after the player completed the foil bestiary, with the Small Spider as their final discovery. The player also suspected quest order, but no developer confirmation establishes that explanation. See the Prismatic Bestiary report.

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.

Check chapter, prestige, and plane progress independently

The progression route in this achievement guide begins with the requirement displayed in Steam. Chapter completion, prestige completion, and plane objectives should each be checked on their own terms.

The launch announcement describes 14 chapters, 10 booster packs, 40 units, and more than 500 upgrades. Those figures describe the full game’s content; they do not establish the number of achievements or a guaranteed completion route. See the official launch announcement.

Progression target	Supported evidence	Recommended check
The Last Crucible	Community reports describe Chapter 4 at Prestige 1	Confirm both chapter and prestige against Steam’s wording
Prestige access	Patch 1.0.30D adds an arrow when the prestige door can open	Inspect the skill-tree reminder
Unfinished quests after Act 1 or 2	The patch allows continued play and quest progress	Review remaining quests before moving on
Plane of Death	The patch reduces enemy difficulty	Retry after updating if combat blocked progress
Frozen Plane	The patch reduces hero health loss in the final blizzard stage	Reassess the encounter on the updated build

For The Last Crucible, community reports identify Chapter 4 at Prestige 1 as the relevant condition. The available evidence does not include a verified sequence for reaching it or explain whether an earlier completion will register automatically after updating.

Use the prestige-door arrow as a navigation aid when it appears. It indicates that the door can open; it does not establish that a particular achievement requirement has been completed.

For plane encounters, the balance changes support trying again on the updated build. The patch also confirms that the Forger’s hammers can be parried and adds a hint explaining that interaction. No supported timing window or guaranteed build is supplied.

Troubleshoot locked achievements after patch 1.0.30D

The repair sequence in this achievement guide follows the developer’s version-check advice and the documented patch changes. Patch 1.0.30D fixes some achievement triggers, but its notes do not identify every affected achievement or guarantee that all reported cases are resolved.

Symptom	Relevant evidence	Next action
Completed collection, locked achievement	Several triggers were fixed	Check your version and restart if still on an older build
Final relic-pack quest reward missing	The patch fixes that reward	Update, then inspect the quest and reward state
Upgrades can no longer be purchased	An integer-overflow issue was fixed	Update before assuming you reached an intended limit
Quests remain after Act 1 or 2	Continued quest progress is supported	Keep playing the completed act if those quests remain relevant
Achievement stays locked on 1.0.30D	Developer requested further investigation for a persistent relic issue	Document the achievement, version, and visible progress

Follow this sequence before committing to another long grind:

1. Identify the requirement. Copy the achievement’s current Steam wording.
2. Check the matching progress. Use the relevant collection, quest, chapter, or prestige state.
3. Confirm your version. Follow the developer’s restart advice if you are on an older build.
4. Recheck after relaunching. Compare the game’s visible progress with Steam’s achievement status.
5. Document a persistent mismatch. Record the locked achievement, collection count, and last relevant discovery or completion.

Updating is a supported first step. Replaying an entire chapter, reacquiring every relic, or resetting progress is not established as a necessary fix by the available evidence.

Likewise, the fixed final relic-pack reward does not prove that an already affected save will receive it automatically. Check what happens in your own game and include that result in any report.

If progress is visibly incomplete, pursue that specific gap. If the relevant collection appears complete and the achievement remains locked on 1.0.30D, a precise report is more useful than repeatedly opening unrelated packs.

Achievement guide FAQ

Which version does this achievement guide cover?

It covers the retail Steam release, with patch 1.0.30D changes explicitly identified, based on evidence collected November 11, 2026. Demo interloper information is labeled separately. The supplied material does not establish matching achievement conditions or fixes for mobile editions.

Do you need to own every relic simultaneously?

That is unconfirmed. A player asked whether previously discovered and destroyed relics must be replaced, but the supplied discussion contains no definitive answer. Check your collection and version before spending resources to reacquire relics.

Does patch 1.0.30D fix every achievement?

The official notes confirm several achievement-trigger fixes. They do not list every repaired achievement or guarantee universal resolution. The developer specifically advised checking 1.0.30D for a relic achievement problem and offered further investigation if it persisted.

How long does earning every achievement take?

A verified achievement-completion estimate is unavailable. The developer describes at least seven hours of full-game content, depending on luck and speed. That is not a 100% achievement estimate, especially while collection-trigger issues remain under discussion.
