Booster Pack Heroes Best Heroes & Upgrade Priorities

Which heroes should you prioritize in Booster Pack Heroes?

Squire is a sensible early investment candidate, Knight offers a defensive role, and Monk and Illusionist have encouraging player-experience evidence. The supplied sources do not establish a measured winner across the retail roster, however. These are recommendations for different situations, with evidence limits explained below.

This guide covers the Steam retail release dated November 10, 2026, with patch 1.0.30D changes identified separately. The official listing confirms that heroes and spells improve through Mastery and that defeating chapter bosses opens additional packs and challenges. Official Steam listing

Treat this best heroes shortlist as an upgrade decision aid. Your next purchase should address what ends your runs: losing heroes too quickly, failing to finish enemies, or lacking enough useful units. A spectacular result from one favorable draw does not establish which investment will improve your next several attempts.

How the main hero candidates compare

The table separates role descriptions from their supporting evidence. The supplied summaries associate several heroes with specific mechanics, but complete retail tooltips, damage measurements, and controlled comparisons are missing.

Hero	Evidence available	Practical recommendation
Squire	Appears repeatedly during the opening gameplay; early progression upgrades are discussed	Consider early investment when Squires make up much of your army
Knight	Blocking is described in gameplay; pre-release community reports also mention stuns	Evaluate when your units need to survive longer
Witch Doctor	Infection is described in gameplay	Consider an infection-focused approach; verify any Skeleton interaction
Demon Slayer	Summary notes associate it with critical hits and kill effects	Check the actual triggers before committing upgrades
Illusionist	Summary notes identify clone generation; a player attributes a successful clear to it	Consider when its current upgrades support your available army
Duelist	Summary notes and gameplay commentary associate it with damage and income	Evaluate its economic benefit alongside combat results
Monk	A player repeatedly praises its performance, including foil draws	Keep it on the shortlist, while accounting for favorable pulls

Squire and Knight: consistency and survival

Squire’s argument is availability during the opening sequence. A hero you repeatedly draw gives you repeated opportunities to benefit from its upgrades. The evidence does not provide a drop-rate percentage, so calling Squire the mathematically most efficient investment would go beyond what is known.

Knight has a clearer defensive identity: the gameplay commentary describes blocking incoming attacks. Community reports on the official itch.io page also mention Knight stuns, but those comments predate retail launch and should be treated as demo-era player experience.

Witch Doctor, Illusionist, and specialized effects

Witch Doctor’s infection makes it worth examining when you want an alternative to straightforward attacks. A Skeleton pairing is suggested in the reference notes, but the supplied material does not establish the exact interaction or required upgrades. Read those descriptions before building around it.

Illusionist receives a favorable assessment in the gameplay transcript. That is useful player experience, although the recording’s build is unconfirmed. Demon Slayer and Duelist likewise deserve inspection rather than automatic priority: critical effects, kill rewards, and income depend on their actual conditions.

For a best heroes comparison, these distinctions matter more than assigning unsupported S-tier labels.

Best heroes: a build decision matrix

A useful build begins with a problem you can identify. If ordinary waves overwhelm your army, an income-oriented option may not address the immediate failure. If your units survive but a boss remains standing, additional defense may produce little improvement.

These are source-based decision criteria, not tested combinations or guaranteed clears.

What happens in your runs	Candidate to evaluate	What to check before investing
Opening armies disappear quickly	Squire upgrades or Knight	Whether the next upgrade improves the units you regularly draw
Your army survives, but enemies remain	Demon Slayer or Duelist	Current damage effects and any critical-hit or kill requirements
You want to explore infection	Witch Doctor	Infection wording and explicitly stated interactions
You want to explore clone generation	Illusionist	Current clone behavior and relevant upgrade descriptions
Combat is manageable, but purchases feel limited	Duelist	Whether its income condition activates often enough to matter

Build around your current collection

Choose a candidate you can actually support. An upgrade for a frequently drawn hero may contribute more often than an appealing effect attached to a hero you rarely see. The sources confirm that packs have different pools, but they do not provide complete retail odds for calculating an optimal purchase sequence.

Likewise, avoid assuming every named effect combines automatically. Infection, Skeleton generation, clones, and kill effects sound compatible in broad terms. Compatibility requires explicit tooltip wording or observed results.

Separate combat progress from economic progress

Duelist illustrates this distinction. The gameplay commentary notices extra income associated with it, but supplies no reliable payout formula. You can reasonably investigate its economic role without claiming it is the strongest damage dealer.

A useful best heroes recommendation should explain what improves. More coins, longer survival, and faster boss kills are different outcomes. Judge a proposed build against the outcome you need next.

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.

Which upgrades make a build more reliable?

The official progression loop supports a practical approach: survive, earn Mastery, improve heroes and spells, and attempt the next challenge. It does not supply a universal upgrade order.

Use the following distinctions to avoid confusing a lucky run with lasting progress.

System	What the sources support	How to use that information
Mastery	Used to improve heroes and spells	Compare available upgrades against your current obstacle
Shop coins	Used for pack purchases in the gameplay demonstration	Consider whether a purchase helps field a useful army
Foil pulls	Foil heroes are part of the game; gameplay shows favorable examples	Read each reveal instead of assuming one universal bonus
Relics	The retail launch announcement lists 40 relics	Evaluate combinations around the relics you actually possess

The relic total comes from the developer’s retail content announcement, which also describes a much larger progression system than the opening chapters alone. Official retail launch announcement

Use a repeatable upgrade check

Before spending Mastery, ask:

• Will this affect a hero or spell I regularly obtain?
• Does its description address what defeated me?
• Does it require another effect I have not unlocked?
• Am I judging it mainly from one unusually strong foil draw?

Then change one major priority and compare the next few attempts. This is a suggested evaluation method, not a documented game mechanic. Look for consistent improvements such as reaching a boss more often or keeping more units alive.

Keep Monk results in context

The gameplay transcript contains enthusiastic reactions to Monk, particularly when multiple foil Monks appear. It also includes attempts where those favorable draws still fail to defeat the boss.

That makes Monk a promising candidate rather than proof of a guaranteed solution. Its reported strength should encourage you to inspect its upgrades, not dismiss the rest of your collection.

The same applies to support options. Player experience mentions useful contributions from Thunderstorm, Raise Dead, Frenzy, and Portal. Their exact retail values are not supplied, so there is no supported formula for pairing them with a particular hero.

Good best heroes decisions account for the whole run: available packs, permanent upgrades, support effects, and the enemy that stops progress.

What do retail, demo, and patch sources confirm?

Version matters to any hero recommendation. A demonstration can show an interesting interaction while leaving its current retail strength unresolved.

Source scope	Confirmed information	Implication for build advice
Retail launch	14 chapters, 10 booster packs, 40 units, more than 500 upgrades, and 40 relics	Opening-chapter impressions cover only part of the available progression
Next Fest demo update	Illusionist upgrades were reworked; enemies and shop rolls were adjusted	Older demo assessments may describe different conditions
Patch 1.0.30D	Plane of Death enemies were weakened, and final-stage blizzard HP loss was reduced	Some survival problems changed without establishing a new hero ranking
Patch 1.0.30D progression changes	Completed acts 1 and 2 can remain playable while quests continue progressing	Players have additional room to continue unfinished progression

The demo update also introduced Interlopers as extremely rare pulls of heroes from full-game packs. That explains their demo role; it does not establish a reliable retail farming strategy or numerical drop rate. Official Next Fest demo update

Patch 1.0.30D additionally fixes upgrade purchasing and certain reward issues. If progression appears broken, check that patch context before concluding that your chosen hero is the problem. The notes contain no direct hero-by-hero ranking or comparative damage data. Official patch 1.0.30D notes

For your next attempt, identify the failure first, inspect one relevant upgrade, and choose a pack that can support the plan. That gives you a concrete decision even while complete retail comparisons remain unavailable.

FAQ

Is there a verified best heroes tier list?

The available evidence does not establish a measured ranking across the full retail roster. Squire and Knight are reasonable early candidates for consistency and defense. Monk and Illusionist have favorable player-experience reports, but those reports do not prove universal superiority.

Is Monk the strongest hero?

That is unconfirmed. The gameplay transcript repeatedly praises Monk, including strong foil appearances, but also records failed attempts with favorable Monk draws. Its performance is encouraging evidence to investigate its upgrades, not a controlled comparison against every other hero.

What is the best build for beginners?

Start with upgrades that benefit the heroes you repeatedly draw, then address the cause of your losses. Evaluate Knight when survival is the issue and inspect damage-oriented effects when enemies survive too long. The sources do not support one fixed beginner combination or guaranteed purchase order.

Should you build around foil heroes or Interlopers?

Treat them as opportunities when they appear. The evidence does not provide reliable retail odds or a guaranteed acquisition method for planning around them. A practical approach is to improve the ordinary draws you regularly receive, then adapt when an exceptional pull gives you another option.
