Collarless is Mewgenics’ classless cat, which means it starts from a very different place than Fighter, Mage, Hunter, or the other named classes.
There is no built-in class stat package telling you what the cat should become.
The current class data lists:
- no class Buffs;
- no class Debuffs;
- no separate unlock method.
That makes Collarless look plain at first, but its strongest mechanics are specifically about building an identity instead of receiving one automatically.
Soul passives can push the cat toward another class’s stat profile and ability pool. Skill Share can turn one passive into a party-wide effect. Unrestricted can completely change once-per-battle actions. Other Collarless passives reward full HP, familiars, low HP, Luck, copies, or strange breeding setups.
Quick answer: Collarless is not a normal generalist class. Its strength comes from finding one mechanic worth copying, sharing, or importing and then building around it. The important decision is usually not “what is the best Collarless spell?” but what do I want this Collarless cat to become?
Collarless at a Glance
| Collarless Trait | Value |
|---|---|
| Role | Custom / cross-class / breeding / passive engine |
| Class stat bonuses | None |
| Class stat penalties | None |
| Standard basic attack in ability data | Melee Attack, 5 Physical Damage |
| Other possible Collarless basics | Includes ranged and replacement basic attacks |
| Best at | Cross-class specialization, passive sharing, unusual build combinations |
| Main weakness | No native class stat package or single guaranteed build direction |
| Unlock | No unlock method listed in current class data |
That last point is important.
The structured class file leaves Collarless’ unlock field blank. I would not turn that into a claim that Collarless is “unlocked by default” unless the game data explicitly establishes that elsewhere.
Collarless Does Not Have One Fixed Combat Identity
Most classes answer the build question immediately.
Hunter wants ranged precision.
Necromancer has Leeches and corpses.
Psychic has Gravity and mana states.
Tinkerer has Tech and equipment.
Collarless does not give you that answer.
Even its basic-attack data reflects that broader identity. The ability pool includes a standard Melee Attack (Collarless) for 5 Physical Damage, but also Collarless ranged basics such as Short Shot and Short Lobbed Shot, plus replacement attacks created by other mechanics.
That means I do not start a Collarless run by deciding whether Collarless is “a melee class.”
I start by looking at the actual cat.
Its passive, mutations, basic attack, inherited mechanics, and later Soul access matter more than the class label by itself.
Soul Passives Give Collarless a Class Direction
One of the most important Collarless systems is the set of class Soul passives.
A Soul does two things:
- it applies a stat package associated with another class;
- it causes abilities from that class to be offered when leveling.
That second effect is the real reason Souls matter.
A Collarless cat does not merely copy some stats.
It can begin developing through another class’s ability pool.
For example:
| Soul | Base Stat Package | Level-Up Effect |
|---|---|---|
| Fighter’s Soul | +2 STR, +1 SPD, -1 INT | Fighter abilities can be offered |
| Hunter’s Soul | +3 DEX, +2 LCK, -1 CON, -2 SPD | Hunter abilities can be offered |
| Mage’s Soul | +2 INT, +2 CHA, -1 CON, -1 STR | Mage abilities can be offered |
| Monk’s Soul | +2 INT, +2 CHA, -1 STR, -1 DEX | Monk abilities can be offered |
Upgraded Soul passives increase those stat modifiers further while keeping access to the corresponding class ability pool.
So a Soul is much closer to choosing a direction for the cat than equipping an ordinary stat passive.
Souls Should Match the Cat You Already Have
I would not choose a Soul just because its parent class is strong.
A Hunter’s Soul makes much more sense on a cat whose basic attack, mutations, or existing passive already benefits from Dexterity, Luck, ranged tools, or Hunter abilities.
Mage’s Soul becomes more attractive when the cat already has a reason to care about Intelligence, Charisma, mana, or spell interactions.
Fighter’s Soul can repair a Collarless cat that needs a clearer physical identity.
Monk’s Soul becomes more interesting when the existing build benefits from spell access, melee/ranged crossover, or action-chain mechanics.
The Soul should resolve ambiguity.
It should not create a second unrelated build on top of the first one.
Skill Share Is a Collarless Passive
Skill Share belongs to Collarless.
It is not a native Jester passive or a generic party mechanic.
The normal version shares Collarless’ other passive ability with the other cats in the party at the start of each battle.
That wording makes the second passive incredibly important.
Skill Share itself does not create the payoff.
It multiplies whatever occupies the other slot.
A mediocre second passive gives the whole party a mediocre effect.
A passive that scales extremely well when duplicated can transform the entire team.
Skill Share Turns One Passive Into a Team Decision
This is why I would evaluate Skill Share differently from almost every normal passive.
Imagine the Collarless cat has:
Skill Share + strong regeneration passive
That second passive is no longer just helping one cat.
The party is inheriting it.
The same logic applies to stat generation, mana support, defensive effects, or any passive whose value scales well with the number of units receiving it.
The important question is therefore:
Is my other passive something I actually want four copies of?
If the answer is no, Skill Share is occupying a valuable slot without enough payoff.
Skill Share+ Is Also a Breeding Tool
The upgraded version adds a second effect:
children will always inherit Collarless’ other passive when breeding.
That gives Skill Share a role outside the current battle.
It can turn a difficult-to-preserve passive into a much more reliable breeding target.
So Skill Share has two separate uses:
combat: duplicate the other passive across the party.
breeding: guarantee inheritance of that other passive.
That makes it one of the clearest examples of Collarless being tied to long-term cat building rather than only one run.
Unrestricted Changes Ability Rules
Unrestricted changes actions with a once-per-battle restriction so they can instead be used once per turn.
The upgraded version keeps that effect and also gives once-per-turn actions a 50% chance to become castable again.
This is not a generic damage increase.
Its value depends entirely on what restricted actions the cat has.
A weak once-per-battle action becoming once per turn is only modestly useful.
A powerful action balanced around being usable once in an entire encounter can become a completely different mechanic.
Why Unrestricted Can Become Absurd
Several abilities in Mewgenics are intentionally limited because their effect is too large to repeat normally.
For example, Monk’s Kamehameha is normally once per battle unless another condition changes it.
One Punch is also designed around a once-per-battle restriction.
If a Collarless build gains access to actions like those through breeding, inherited mechanics, or cross-class development, Unrestricted attacks the limitation rather than the damage number.
That is often much more powerful than simply adding +2 Damage.
The passive is effectively asking:
What action in this build was balanced around scarcity?
That is the action worth pairing with Unrestricted.
Overconfident Is a Full-HP Spell Engine
Overconfident reduces spell costs by 2 mana while Collarless is at full HP.
It cannot reduce a spell below 1 mana.
The downside is severe:
Collarless takes double damage while the condition is active.
The upgraded version also heals 1 HP whenever a spell is cast.
This creates a strange but coherent backline build.
If the cat can stay out of danger, reducing every spell by two mana can generate a large amount of extra casting.
If the cat gets hit, the full-HP condition disappears.
And if that hit happens while Overconfident is active, the double-damage downside can make the mistake much worse.
Overconfident Wants Safety, Not Toughness
This is not the passive I want on a Collarless cat standing in front.
The important defensive question is not:
Can this cat survive several hits?
It is:
Can this cat avoid being hit at all?
Range, Shield, Holy Shield, positioning, control, familiars, or another cat absorbing pressure can all help maintain the full-HP state.
That is what keeps the mana discount online.
Unscarred Rewards the Same Full-HP Condition
Unscarred gives 100% critical-hit chance while at full HP.
The upgraded version keeps the guaranteed crit condition and adds:
- +5 Mana Regeneration;
- +1 All Stats Up.
This naturally points toward a cat that can operate safely from range or maintain strong protection.
It also pairs conceptually with Overconfident because both want the same board state:
do not lose HP.
One turns that condition into spell economy.
The other turns it into guaranteed crits.
That is a much more coherent pairing than combining two individually strong passives whose conditions disagree.
Full HP Is Fragile
A full-HP Collarless can look incredible on paper.
Guaranteed crits.
Cheaper spells.
Possibly additional mana regeneration after upgrades.
But one point of real HP damage can turn off a large part of the engine.
That makes Shield especially different from healing.
Healing fixes the build after HP is lost.
Shield can prevent the full-HP condition from breaking in the first place.
For this version of Collarless, preventing the hit is often worth more than recovering from it later.
Mini-Me Copies the Cat, Not Just One Attack
Mini-Me gives Collarless an AI-controlled half-sized copy with 50% of the original cat’s stats.
The upgraded version adds another quarter-sized copy with 25% of the original stats.
This is useful precisely because Collarless builds can become so strange.
The copy is not a generic squirrel or robot.
It is a reduced version of the actual cat.
A well-built Collarless therefore gives Mini-Me much more interesting material to copy than an unfocused one.
The stronger and more coherent the original cat becomes, the more attractive copying that package becomes.
Mini-Me Also Copies Your Problems
The extra bodies are AI controlled.
That means I would not evaluate Mini-Me as though I have precise control over several full player characters.
Resource-heavy or awkward abilities can also create practical problems when extra copies are using the same style of kit.
The gameplay material specifically calls out coin-costing actions as one example where copies can burn through a limited resource quickly.
So Mini-Me works best when the cat’s kit remains useful even when an AI copy is making its own decisions.
Strength in Numbers Is a Familiar Scaling Engine
Strength in Numbers gives each familiar:
+1 Damage for every other familiar you have.
The upgraded version applies that same scaling to Collarless itself as well as its familiars.
This grows much faster than a simple +1 Damage passive.
With one familiar, there is little to multiply.
With a large board of familiars, every familiar is receiving Damage from the existence of all the others.
That makes mass-summon mechanics dramatically more attractive.
A Squirrel Squad-style board, multiple vermin, or another large familiar package can turn one Collarless passive into team-wide summon scaling.
Strength in Numbers Needs Quantity
This passive exposes an important distinction between large summon and many summons.
One powerful familiar may be excellent for Super Friends or other quality-focused effects.
Strength in Numbers specifically wants body count.
A Collarless with one elite familiar is barely using the passive.
A Collarless surrounded by several smaller familiars is feeding every one of them additional Damage.
So the summon source matters just as much as the passive.
Careful Is About Friendly Fire
Careful reduces damage Collarless deals to allies to 0.
The upgraded version also prevents Collarless from inflicting debuffs on allied units.
That can matter much more in builds with large areas, explosions, indiscriminate effects, or spells that are difficult to aim around the party.
It does not increase the damage ceiling directly.
It changes what you are allowed to cast safely.
That can open up aggressive area effects that would otherwise require the whole party to constantly reposition around Collarless.
Pulp Turns Kills Into Meat
Pulp makes a unit or corpse become meat when Collarless kills it or destroys the body.
The upgraded version also grants +4 Damage.
This is not automatically an engine by itself.
Its value depends on whether the rest of the party can actually use the food generation.
But in a build already connected to food, pickups, familiars, or other consumption mechanics, Pulp gives every kill a second output.
The enemy is not only dead.
It becomes another resource on the board.
Death’s Door Creates a Completely Different Collarless
Death’s Door reduces spells to 1 mana while Collarless is at exactly 1 HP, with each spell limited to once per turn.
The upgraded version expands the condition to 5 HP or less.
This is the opposite of Overconfident.
Overconfident wants perfect health.
Death’s Door wants Collarless on the edge of death.
Those two passives should not be treated as generic mana-reduction pieces.
Their conditions point toward completely different runs.
Zenkai Boost Makes Ending at 1 HP Matter
Zenkai Boost rewards finishing a battle at exactly 1 HP.
When that happens, Collarless:
- permanently gains +1 to a random stat;
- starts the next battle at full HP;
- starts that battle with All Stats Up 3.
The upgraded version grants +1 to 3 random stats permanently.
This creates a rare case where ending a fight barely alive is not just something to survive.
It is a progression condition.
Combined with low-HP mechanics, this can create a build where managing the bottom of the health bar is intentional rather than accidental.
The obvious danger is that 1 HP is still 1 HP.
If the fight is not already under control, chasing the permanent stat reward can simply get the cat killed.
Collarless Has Opposite Health Builds
This is one of the reasons the class should not be reduced to a single “best build.”
A full-HP Collarless may use:
Unscarred + Overconfident
and spend the entire fight trying not to lose HP.
A low-HP Collarless may instead care about:
Death’s Door + Zenkai Boost
and deliberately operate near the bottom of the health bar.
Both are valid Collarless identities.
They want almost opposite defensive decisions.
Lucky Is Simple on Purpose
Lucky gives +4 Luck.
The upgraded version gives +7 Luck.
There is no complicated trigger or engine.
That simplicity can actually be useful on Collarless because the class does not always need another mechanic to manage.
If the cat already has crits, random effects, or abilities that benefit from Luck, Lucky can support them without demanding a new play pattern.
Not every Collarless passive needs to redefine the character.
Collarless Build Directions
Unlike the other Class pages, I would not classify these builds by damage type.
They are better classified by what is providing the cat’s identity.
Soul-Specialized Collarless
A Soul passive becomes the foundation.
Hunter’s Soul can turn the cat toward Dexterity, Luck, and Hunter ability access.
Mage’s Soul can create an Intelligence / Charisma caster.
Fighter’s Soul creates a clearer physical direction.
Monk’s Soul opens Monk’s hybrid ability pool.
The important part is committing to that class identity strongly enough that the rest of the cat stops feeling random.
Skill Share Support Collarless
This build is defined by the other passive.
Skill Share is only the multiplier.
The second passive is the payload.
Effects that remain useful when every cat receives them are much more interesting than selfish passives whose extra copies do little.
The upgraded breeding guarantee makes the same Collarless useful as a long-term genetics tool as well.
Unrestricted Build
This version needs a powerful restricted action.
The more important the once-per-battle limitation was to balancing the ability, the more value Unrestricted can create.
It is therefore a build that should be designed backward:
find the action worth repeating first, then value Unrestricted.
Taking Unrestricted with no meaningful restricted action leaves the passive waiting for a payoff that may never arrive.
Full-HP Collarless
Unscarred and Overconfident both reward staying untouched.
This version prefers range, protection, control, or another frontline cat.
The entire engine can disappear after one HP-damaging hit, so preventing damage matters more than simply having a large maximum-health pool.
Low-HP Collarless
Death’s Door and Zenkai Boost pull in the opposite direction.
This cat wants to survive at extremely low HP and extract mana efficiency or permanent scaling from that state.
The ceiling can be interesting, but this is inherently much less forgiving than the full-HP route.
Familiar Collarless
Strength in Numbers, Mini-Me, Animal Handler, and imported summon tools can turn Collarless into a familiar-heavy build.
Strength in Numbers wants quantity.
Mini-Me wants the original cat itself to already be worth copying.
Those are two different ways of scaling extra bodies, and they can overlap when the board has enough room.
The Biggest Collarless Mistake
The most common mistake is trying to make Collarless “versatile.”
That sounds appropriate for a classless cat, but it often produces the weakest version of the class.
One Soul passive.
One summon spell.
One low-HP passive.
One random ranged mutation.
One support spell.
None of those pieces are necessarily bad.
The problem is that they are answering different questions.
A strong Collarless build usually becomes less general as the run develops.
The cat starts classless, but by the middle of the run I want to be able to describe what it actually is:
a Skill Share support cat
or:
a Hunter-Soul ranged crit cat
or:
an Unrestricted build abusing a powerful limited action
or:
a familiar engine
or:
a full-HP spell and crit engine
That is when Collarless stops feeling like the absence of a class.
Why Breeding Matters More for Collarless
Other classes already provide a large part of their identity through class stats and class ability pools.
Collarless can depend much more heavily on what the individual cat inherits.
That makes breeding especially important when the goal is to preserve:
- a specific passive;
- a useful mutation;
- a particular basic-attack interaction;
- a cross-class package.
Skill Share+ is one of the clearest examples because it directly guarantees inheritance of the other passive.
The value of the cat can therefore exist partly outside the current run.
A great Collarless parent can be useful because of what it enables in later generations.
Skill Share and Souls Solve Different Problems
These two systems can look similar because both connect Collarless to abilities outside its normal identity.
They are not the same.
Soul passives change the Collarless cat itself. They give stats and allow another class’s abilities to appear during level-ups.
Skill Share pushes Collarless’ other passive outward to the rest of the party.
One imports an identity.
The other exports a passive.
That distinction is useful when deciding what the cat’s role should be.
When Collarless Starts Working
The turning point usually happens when one mechanic becomes important enough that the rest of the build can be judged against it.
A Fighter’s Soul cat no longer needs random caster pieces just because they are available.
A Skill Share cat can reject selfish passives that do not scale across the team.
A full-HP cat can prioritize protection over normal sustain.
An Unrestricted cat can prioritize one exceptional limited-use action rather than collecting several average spells.
A familiar cat can start measuring new choices by how many bodies they create or improve.
That is the real progression of Collarless:
the class starts undefined, then the build gradually defines it.
Is Collarless Worth Building Around?
Collarless does not have the clean starting identity of the other Mewgenics classes.
There is no +4 Constitution Tank package, no Hunter Dexterity package, no Mage spell identity, and no Psychic Gravity engine built into the class entry itself.
Instead, its strongest mechanics work one level above normal class design.
Soul passives let it borrow another class’s direction.
Skill Share turns one passive into a party mechanic and later a breeding guarantee.
Unrestricted changes ability usage rules.
Mini-Me copies the cat itself.
Strength in Numbers rewards familiar quantity.
Overconfident and Unscarred create a full-HP build, while Death’s Door and Zenkai Boost create almost the exact opposite.
That is why Collarless should not be built as “a little bit of everything.”
Its strongest identity is usually something much more specific:
find one exceptional rule, then make the rest of the cat serve that rule.
