Booster Pack Heroes Squire Upgrades & Early Investment

What do we know about squire upgrades?

The most useful starting point is separating what was observed from what the developer officially documents. The official game description confirms that surviving earns Mastery, which you spend on hero and spell upgrades. It does not provide a complete Squire skill tree or its individual costs. Official Steam listing

Upgrade	Available detail	Evidence status
Squire Might	+50% attack damage; costs 10 Mastery	Observed tooltip recorded in the reviewed notes
Squire Training	First evolution after 2 kills, further evolution after 3 kills, full healing on evolution	Community reports from a gameplay guide; exact build not established

These are the two named Squire upgrades supported by the reviewed notes. Their presence here does not establish a complete upgrade list.

For the retail Steam release, use these details as a starting point and compare them with your current tooltips. A matching name is useful, but the displayed effect, cost, and conditions determine whether the observation applies to your version.

How to evaluate Squire Might’s damage bonus

Squire Might provides the clearest numerical information available for squire upgrades: the observed tooltip shows a 50% attack damage increase costing 10 Mastery.

On its own, a 50% increase means multiplying the relevant starting damage by 1.5. That arithmetic explains the stated bonus; it does not establish how the game combines Might with other modifiers. The available evidence contains no stacking formula, damage breakdown, or controlled comparison.

The practical question is whether stronger Squire attacks address the problem ending your runs. If the Squire is regularly attacking enemies that survive those hits, increased damage is a reasonable upgrade to consider. If the unit rarely gets an opportunity to attack before your defense collapses, the percentage alone does not demonstrate that Might is your best purchase.

Before spending Mastery:

• Read the current tooltip. Check whether it still displays the observed 10-Mastery cost and 50% attack bonus.
• Identify the immediate obstacle. Distinguish enemies surviving attacks from your units failing to stay alive long enough to contribute.
• Compare available alternatives. Use their actual effects and prices, rather than an assumed universal upgrade order.

These are recommendations based on the documented effect, not a tested ranking of the skill tree.

Also keep the bonus’s scope in mind. A Squire attack upgrade supports the unit’s damage contribution. The available tooltip observation does not establish a matching increase to health, healing, attack speed, or your army’s overall damage.

That makes Might straightforward to assess, even though the evidence does not establish it as the strongest early purchase.

What community reports say about Squire Training

Squire Training is the more conditional part of squire upgrades. The reviewed gameplay-guide notes describe a first evolution after two kills, a further evolution after three kills, and a full heal when evolution occurs.

Those details are community reports, with the guide’s exact build unconfirmed. They are not Squire-specific guarantees published in patch 1.0.30D.

Reported event	Community observation	Detail still unresolved
First evolution	Happens after 2 kills	Exact kill-credit rules
Further evolution	Happens after 3 kills	Whether that count resets or refers to a cumulative total
Evolution healing	Fully heals the evolving unit	Interaction with other health modifiers

The second threshold deserves particular care. The notes do not establish whether “three kills” means three additional kills after the first evolution or three kills overall. An exact combined kill requirement would therefore go beyond the evidence.

The same limitation applies to later progression. The supplied material does not establish evolved-form names, additional evolution stages, their stats, or Training’s purchase cost.

For a useful in-game check, observe one Squire through its first reported threshold. Watch its visible transformation and health, and consult any available description explaining the trigger. This helps you compare your build with the community account without assuming an undocumented progression chain.

If the reported full heal occurs, evolution could help a damaged Squire remain useful longer. That is a source-based strategic interpretation. Its value depends on reaching the trigger before the unit dies; the report does not establish continuous regeneration or a guaranteed survival loop.

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.

How should you prioritize squire upgrades?

Prioritize the obstacle you can actually observe. A damage bonus and a kill-triggered evolution solve different problems, so the available evidence supports a conditional decision rather than a fixed purchase sequence.

The official progression loop links survival, Mastery, and stronger heroes and spells. That gives you a useful framework: choose an upgrade with a plausible connection to surviving your current encounters. It does not make every hero upgrade equally valuable in every run.

What you observe	Reasonable next step	Basis for the recommendation
Squires attack regularly, but enemies survive their hits	Consider Might after checking its current tooltip	Its observed effect increases attack damage
A damaged Squire approaches a reported evolution trigger	Watch whether evolution restores its health	Community reports describe a full heal
Squires die before reaching evolution	Reassess the immediate survival problem	A conditional heal requires the trigger to occur
Another part of your defense repeatedly fails	Compare upgrades affecting that weakness	Mastery also supports other heroes and spells

Treat this table as decision guidance, not a measured tier list. The source material does not provide enough comparative results to calculate the best Mastery efficiency across the whole collection.

A practical evaluation takes three steps.

First, identify what happens immediately before the run falls apart. “I need more power” is less useful than “these enemies survive several Squire attacks” or “the Squire dies before evolving.” A specific observation points toward an effect you can assess.

Second, read the relevant node before buying it. For Might, compare the damage bonus and cost with the recorded observation. For Training, look for wording that explains the kill requirement and evolution behavior. The current description matters more than an unsupported assumption about the branch.

Third, watch the next run for the outcome you intended to improve. For Might, that means the Squire’s contribution against enemies it attacks. For Training, it means whether evolution occurs and what happens to health.

Keep expectations narrow. One successful run can show that your setup worked in that encounter, but it cannot establish an optimal build for every chapter. Likewise, one failed run does not isolate the value of a single upgrade when the rest of the encounter differs.

Retail, demo, and patch 1.0.30D: which evidence applies?

The retail Steam game released on November 10, 2026, according to its official store listing. This article’s retail context is that release, using evidence collected on November 11. The Squire-specific observations remain separately qualified because their exact builds are not established. Official retail release listing

The Steam demo has its own listing and update history. Its existence and documented changes should be kept distinct from retail mechanics. Official Demo listing

Evidence	What it establishes	How it affects this guide
Retail Steam listing	Mastery upgrades heroes and spells	Confirms the general progression system
Next Fest demo announcement	Demo changes included fairer shop rolls and skill-tree visual improvements	Shows why demo observations need version context
Patch 1.0.30D announcement	Fixes an upgrade-purchase overflow issue and allows continued play after acts 1 or 2	Provides relevant troubleshooting and progression information

The official Next Fest demo announcement also documents enemy balance adjustments. Older player experience may therefore reflect different encounter conditions.

For squire upgrades, the most relevant patch 1.0.30D fix concerns an integer overflow that could prevent further upgrade purchases. If purchases stop working unexpectedly, check your installed version against the official patch 1.0.30D notes. That documented bug does not mean every unavailable node has the same cause.

The patch also lets players continue completed acts 1 or 2 while quests keep progressing. This is useful progression context, but it does not establish unrestricted replay of every individual chapter. The notes contain no Squire-specific damage or evolution changes, so they do not independently verify the reported values.

One search-result trap is worth addressing: an itch.io comment discusses clearer wording for “Pack in a Pack,” mentions a Squire upgrade, and proposes a 15% extra-pack description. That is player experience about wording, not a verified Squire pack-generation effect. Do not use it to assign the Squire an extra-pack chance. Player discussion on the official itch.io page

FAQ

Which squire upgrades should I buy first?

Consider Squire Might when increased Squire attack damage addresses your current obstacle and its tooltip matches the observed effect. Evaluate Training through its current description and reported evolution behavior. The available evidence does not establish a universal Might-first or Training-first order.

How much Mastery does Squire Might cost?

The reviewed tooltip observation records 10 Mastery for +50% attack damage. That is an observed value, not a Squire stat independently confirmed by patch 1.0.30D. Check the displayed cost and effect in your installed build before purchasing.

How many kills does Squire Training require?

Community reports describe a first evolution after two kills and a further evolution after three kills. The notes do not clarify whether the later count is additional or cumulative, so an exact total across both stages remains unconfirmed.

Does Squire evolution fully heal the unit?

Community reports describe a full heal on evolution. The available official material does not specify that behavior or its interactions with other effects. Watch the evolving Squire’s health in your current build before relying on the reported heal as part of your survival strategy.
