Booster Pack Heroes Beginner Guide & Early Upgrades

What should you do during your first runs?

The core progression is straightforward: open packs for heroes and spells, defend the tower, earn Mastery through survival, and use upgrades to improve future attempts. Defeating chapter bosses unlocks additional packs, heroes, spells, and challenges, according to the official Steam game description.

For your opening attempts, concentrate on four checkpoints:

Checkpoint	What to inspect	Practical next step
During combat	Tower HP and approaching monsters	Watch when your defense begins to struggle
At the pack purchase screen	Available Basic Packs and your Coins	Check whether a purchase also advances a quest
In the quest list	Requirements and displayed rewards	Work toward a reachable income objective
Between attempts	Earned Mastery and available upgrades	Read an affordable upgrade’s effect before buying

Demonstration evidence: The reviewed opening material shows a Basic Pack purchase, attention to Tower HP, and Mastery spending between attempts. One opening screenshot records the quest Open 2 Basic Packs with a reward of +1 income. This supports checking early quests; it does not establish a complete retail purchase order or universal pack price.

After a loss, identify one thing to improve. Perhaps you can complete that opening quest, purchase a relevant upgrade, or understand an ability you just discovered. You do not need to solve the entire skill tree before starting again.

Keep the goal small enough to evaluate. “Complete one income quest” gives you a clearer next step than “get a perfect collection.”

Coins, Mastery, and Folium: what each label tells you

Resource confusion can lead to poor purchase decisions. This beginner guide separates the resources named in the reviewed material while keeping their confirmed uses distinct.

Mastery has the clearest official explanation: survival earns it, and it improves heroes and spells or unlocks abilities. The opening notes also identify Coins and Folium, but they do not provide an equally complete explanation of every resource.

Resource	What the evidence establishes	How to approach it
Coins	The reviewed opening loop connects them with pack purchases	Check the displayed purchase cost and your available balance
Mastery	Official descriptions connect survival with hero and spell upgrades	Review upgrade options between attempts
Folium	Its earning and spending rules are not established in the available material	Read its current in-game explanation before planning around it

Income is another label to watch. The reviewed Open 2 Basic Packs quest awards +1 income, but that observation does not establish every income source or a complete earnings formula. Check the reward shown on each quest rather than assuming all quests provide the same benefit.

Source-based recommendation: When choosing a Mastery purchase, favor an upgrade whose description addresses something you observed during the previous attempt. An improvement for a hero or spell available from your current packs has an understandable purpose.

That is a decision rule, not a verified optimal build. The supplied official descriptions do not establish a universal upgrade ranking, exact Mastery returns per enemy, or a complete cost curve.

Before spending, ask three questions:

• Which resource does this purchase require?
• What does the displayed description say it changes?
• Will that effect help with my current objective?

These checks keep pack purchases and between-run upgrades connected to your immediate progress.

Beginner guide to packs and upgrades

Each booster pack has its own pool of heroes and spells. Opening packs expands what you discover, while Mastery develops the power and abilities of your collection. Those systems work together, but a new pack and an upgrade answer different needs.

A useful purchase starts with the information currently visible in the game. Read available pack information, inspect quest requirements, and compare upgrade descriptions before deciding.

Your current situation	Information to check	Source-based recommendation
A Basic Pack quest is unfinished	Required openings and its reward	Consider advancing the quest while making pack purchases
You have earned Mastery	Affordable upgrades and their effects	Choose an improvement with a clear use
A chapter boss unlocks more content	Your current chapter objective	Work toward the boss while improving your collection
A newly discovered spell is unfamiliar	Its current ability description	Learn its effect before planning a combination around it

Avoid treating rarity alone as a complete purchase plan. The official description emphasizes rare discoveries, but the available evidence does not include a retail tier list, comparative damage table, or verified best opening combination.

Similarly, the material does not support a guaranteed sequence of early pulls. A launch-day player review described similar openings across two playthroughs, but that is player experience, not confirmation of the game’s complete randomization rules.

You can make progress without resolving that question. Focus on the pack options, quests, and upgrades your game actually presents.

The practical approach in this beginner guide is to connect each purchase to a purpose: advance a visible quest, discover something from an available pack, or improve a relevant hero or spell.

For example, if you are working toward the reviewed two-Basic-Pack quest, inspect its progress before purchasing. Once the requirement is satisfied, reassess your next objective instead of continuing the same purchase pattern automatically. This uses an observed quest without inventing a fixed shopping script.

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.

Bosses, quests, and the changes in patch 1.0.30D

Chapter bosses are progression milestones. The official description states that defeating them opens access to additional packs, heroes, spells, and challenges. A sensible early objective is therefore to improve your collection enough to overcome the current chapter’s obstacle.

Quests give you smaller goals along that route. Check their requirements alongside your available upgrades, especially when another attempt ends without a boss victory.

Several changes in the official patch 1.0.30D announcement affect progression decisions:

Confirmed patch change	Why it matters
Players can continue acts 1 and 2 after finishing them, with quests still progressing	Completing an act no longer requires immediately leaving unfinished quests behind
An arrow in the skill tree points toward the prestige door when it can open	The tree provides a reminder when that progression option becomes available
An upgrade-blocking integer overflow issue was fixed	An inability to buy upgrades could have been a technical problem
The final relic pack quest reward was fixed	A missing reward had an acknowledged bug fix

The progression advice in this beginner guide is to check unfinished quests and visible prompts before deciding what to pursue next. The act-continuation change supports doing this after finishing acts 1 or 2; it does not establish unrestricted replay of every individual chapter.

Prestige also needs careful handling. The patch confirms the door reminder, but the available evidence does not explain its complete requirements, rewards, or reset rules. When it becomes available, read the game’s explanation before proceeding.

Community reports: Launch discussions included achievement problems and missing relic concerns. The patch says several achievement issues and a relic quest reward were fixed. That does not confirm that every reported completion problem was resolved; the Steam community hub contains reports as well as developer announcements.

Which version does this beginner guide cover?

This article covers the Steam retail release dated November 10, 2026, with patch 1.0.30D changes identified separately. The official Steam listing confirms the retail release date and Windows and macOS support.

The developer’s launch announcement establishes the full game’s broader scope:

Retail content	Announced amount
Chapters	14
Booster packs	10
Units available to pull	40
Upgrades	More than 500
Relics	40

These are figures from the official retail launch announcement, not a list of what is immediately available during the opening chapter. They help explain why early pack options represent only part of the progression.

The demo is a separate product with an April 30, 2026 release date on its official Steam demo listing. Its Next Fest update introduced Interlopers as very rare pulls featuring heroes from packs included in the full game. That is explicitly demo-specific evidence, as described in the official demo update.

Do not use that announcement to assume identical retail Interloper odds or behavior.

Mobile editions also have official listings on the Apple App Store and Google Play. Their existence does not establish that Steam patch 1.0.30D applies to those editions. The supplied Apple listing identifies version 1.0.16 separately.

When comparing advice with your game, check the edition and version first. Opening demonstrations can explain a visible interaction, while current retail announcements establish the specific changes they describe.

Beginner guide FAQ

What should I do after my first loss?

Check your earned Mastery, inspect available upgrades, and review unfinished quests before starting again. The official progression model connects repeated runs with growing power. Choose one reachable improvement so your next attempt has a clear objective.

How do I earn and spend Mastery?

The official description says survival earns Mastery and that it upgrades heroes and spells or unlocks abilities. The reviewed opening material shows spending it between attempts. Exact per-enemy payouts and a complete retail earnings formula are not confirmed here.

Which pack should beginners buy first?

The reviewed opening material includes a Basic Pack purchase and an Open 2 Basic Packs quest awarding +1 income. That makes your current quest list worth checking. This beginner guide does not establish a universally optimal pack order or fixed early purchase prices.

Can I keep progressing quests after finishing an act?

Patch 1.0.30D explicitly allows continued play and quest progress after completing acts 1 or 2. Use that opportunity to inspect unfinished objectives. The announcement does not describe unrestricted chapter replay or provide a complete guide to prestige requirements.
