catch a monster traits Explained
Traits are special pet modifiers introduced with the Patch 0.39 systems update. A monster may receive a trait when it is caught, hatched, or created through breeding. Traits are separate from a pet’s element, rank, mutation, evolution stage, and base statistics, so they should be evaluated as an additional layer of value rather than a replacement for those systems.
Open your pet inventory and use the dedicated Trait tab to check whether a monster has one. Pets obtained before the trait system may not display a trait immediately. Breeding older pets is one way to create offspring that can roll a new trait while still carrying relevant inherited characteristics.

The exact value of a trait depends on the pet’s role and the activity where you use it. A damage-oriented trait may be more useful on a primary attacker, while a defensive or utility trait can be stronger on a tank, support pet, or activity-specific specialist.
| Pet Value Layer | What It Describes | Why It Matters |
|---|---|---|
| Element | Normal, fire, grass, ice, ground, or another listed type | Influences matchup and team planning |
| Rank | Rarity and power tier | Determines eligibility and progression value |
| Mutation | Inherited visual or mechanical variation | Can add collection and build value |
| Trait | Special modifier attached to a pet | Adds another optimization target |
| Evolution Multiplier | Random bonus affecting base stats | Can make bred offspring especially valuable |
The Catch a Monster Wiki pet index is useful for checking listed elements, ranks, evolution chains, locations, and available monster records. Use the in-game Trait tab as the final check for the current trait attached to an individual pet.
Do not judge a trait in isolation. Compare it with the monster’s element, rank, base stats, mutation profile, and intended activity before replacing a team member.
Combat Traits
Best considered for primary attackers and monsters used in repeated boss encounters. Prioritize effects that improve the pet’s damage pattern or survivability.
Defensive Traits
Useful on durable monsters, taunt users, and pets assigned to difficult encounters where staying active matters more than maximum damage.
Activity Traits
Some effects may become more valuable in specialized content such as Endless Spire, Delve Trials, dungeons, or rifts.
How to Start Breeding Monsters
Breeding takes place at the nursery in a side area of Skyheart Island. Walk to the breeding panel to open the parent-selection interface. The system requires one male and one female monster, which makes gender tracking an important part of long-term collection management.
The available parent list is separated by gender. If two desirable monsters do not appear together, check whether both are the same gender before assuming the system is unavailable. Breeding also has a rank requirement, so keep high-rank duplicates rather than automatically fusing or releasing every extra pet.
Prepare Two Compatible Parents
Select one male and one female monster that meet the breeding requirement. The available information indicates that S-rank-or-higher monsters are used for this system, so verify the current requirement in the nursery interface.
Choose Your Inheritance Goals
Decide whether you are targeting a trait, mutation, a particular species outcome, or a stronger evolution multiplier. Avoid breeding without a clear goal when Genesis Fruit is limited.
Add Genesis Fruit
Use Genesis Fruit to activate the breeding attempt. The item can be obtained through sources such as the dungeon shop, Spire-related shop access, or the relevant event economy described for the patch.
Start the Nursery Timer
Confirm the parents and begin the process. The breeding timer is approximately four hours, after which you can return to inspect the offspring.
Review the Offspring
Check the new pet’s gender, rank, trait, mutation, evolution status, and multiplier. Keep promising results for testing instead of judging only by the first visible trait.
The reported breeding outcomes make parent selection more important than simply choosing the two strongest monsters in your inventory. Two high-rank parents can improve the chance of a higher-rank result, while parents with combined mutations can give the offspring access to more inherited possibilities.
| Breeding Factor | Practical Rule | Planning Note |
|---|---|---|
| Gender | Use one male and one female parent | Confirm both lists before spending materials |
| Rank | S-rank-or-higher parents are required according to the patch explanation | Check the current nursery UI if the requirement changes |
| Trait | A parent trait may improve the chance of a traited offspring | Trait inheritance is not presented as guaranteed |
| Mutation | Parent mutations can be passed into offspring | Combining mutation options broadens possible results |
| Timer | About 4 hours per attempt | Start breeding before leaving the game |
Genesis Fruit is a limited breeding material in the described patch economy. Save it for pairs that support a specific trait, mutation, rank, or multiplier goal.
Trait Inheritance and Offspring Quality
The most important distinction is between inheritance and new rolls. A parent with a trait may pass that trait to the child, but the offspring can also gain a different trait. Even two parents without visible traits may still produce an offspring with a newly discovered trait according to the system explanation.
This makes breeding useful for both preservation and experimentation. If you already own a monster with a valuable mutation, pair it with a compatible parent that expands the possible result rather than treating the mutation as disposable. The offspring can retain inherited characteristics while also receiving a separate trait and a random evolution multiplier.
The breeding system also appears to reward quality stacking. When both parents are top-rank monsters, the chance of producing a higher-rank offspring is stronger than when one parent is merely S rank. The reported examples describe a 40% chance for a double-SS result when using two double-SS parents and 20% when one parent is S rank. Because these figures are tied to the referenced patch explanation, confirm the displayed odds before each attempt.
| Parent Combination | Reported Higher-Rank Chance | Recommended Use |
|---|---|---|
| Two double-SS parents | 40% chance to produce double SS | Best for premium breeding attempts |
| One double-SS and one S-rank parent | 20% chance to produce double SS | Useful when matching genders or resources are limited |
| Two parents without visible traits | Trait may still appear on offspring | Experiment only when the material cost is acceptable |
| Parents with traits | Higher trait probability is expected | Preferred for targeted trait hunting |
Mutation results should also be read carefully. Having two parents with different mutations does not automatically make each mutation more likely. The useful principle is to combine desired mutation options across the pair, then accept that the offspring may inherit only part of that pool.
A bred pet may also gain an evolution multiplier that raises its base-stat potential. This is one reason a lower-priority breeding result should not be discarded immediately. Compare its actual statistics and multiplier with your current roster before deciding.
Use one parent to preserve a valuable trait or mutation and the other to add rank, gender compatibility, or a second inheritance option.
Trait Parent
Increases the value of the attempt by offering a known trait for possible inheritance.
Mutation Parent
Preserves a mutation line and expands the offspring’s collection potential.
Rank Parent
Supports higher-rank outcome testing when the nursery displays a favorable chance.
Multiplier Result
Adds a random evolution multiplier that may improve the child’s long-term statistics.
Rerolling Traits and Building Better Pets
Once you have bred a promising monster, inspect its trait and evolution information before investing more resources. The patch explanation states that bred pets can have their evolution multiplier rerolled with a Chaos Potion, even when the multiplier bar is not initially visible. After using the potion, the bar can appear and become available for rolling.
This creates a two-stage optimization route:
- Breed for a strong species, rank, inheritance profile, or new trait.
- Inspect the child’s evolution multiplier.
- Use a Chaos Potion only when the pet is valuable enough to justify another resource.
- Compare the rerolled result with the original before committing to the new value.
Do not assume that every trait is best on every monster. For example, the new Soul Griffith is described with a passive that reduces pet damage taken in Endless Spire by 35%, making it especially relevant to Spire teams. Storm Horn is described with a taunt ability that forces nearby monsters to target it briefly while granting 35% damage reduction for 10 seconds. Its other passive is associated with Delve Trials, where it increases pet damage by 50%.
These examples show why trait and passive evaluation must include the activity. A defensive effect can be more valuable than raw damage in Endless Spire, while a Delve Trials bonus may have limited impact outside that content.
| Build Goal | Preferred Evaluation | Example Consideration |
|---|---|---|
| Endless Spire | Damage taken, uptime, taunt control | Soul Griffith’s reported Spire defense passive |
| Delve Trials | Activity damage and survival | Storm Horn’s reported Delve Trials bonus |
| Dungeon Progression | Clear speed and boss consistency | Favor reliable damage and defensive coverage |
| General Collection | Trait rarity, mutation, evolution, rank | Keep unusual results for later comparison |
The digging event can help support this broader progression loop by providing Rift Coins, which can be exchanged for shovels. Defeating monsters and bosses, remaining online for the stated daily period, and using the shovel tiers efficiently can improve access to event rewards. However, event farming should support your breeding plan rather than replace it.
A trait or passive that looks average in general content may become a high-value choice in Endless Spire, Delve Trials, dungeons, or rift encounters.
Trait Breeding Checklist:
- Confirm the parents are one male and one female
- Verify both monsters meet the nursery rank requirement
- Choose a clear trait, mutation, rank, or multiplier goal
- Keep Genesis Fruit available before starting the attempt
- Inspect the offspring before using a Chaos Potion
Trait Progression Priorities and FAQ
A good trait collection grows through controlled testing. Start by recording which parents produced each result, then compare offspring by activity rather than relying on visual rarity alone. Keep a simple roster of parent gender, rank, element, mutation, trait, and multiplier so future breeding attempts become more deliberate.
The current indexed wiki data lists 231 monsters, including multiple elements, ranks, and evolution chains. That scale makes inventory organization essential. Tag or reserve monsters with unusual traits, strong mutations, compatible genders, or valuable activity passives before using them for fusion or other upgrades.
| Priority | What to Track | Why It Helps |
|---|---|---|
| High | Trait and activity effect | Shows where the pet performs best |
| High | Gender and breeding compatibility | Prevents unusable parent pairs |
| Medium | Rank and evolution stage | Helps estimate upgrade and breeding value |
| Medium | Mutation combination | Supports inheritance planning |
| Medium | Evolution multiplier | Identifies high-potential bred offspring |
Use the Catch a Monster Wiki to review the broader monster index, then verify live trait behavior in your inventory and nursery screens. Patch systems can change, and the in-game interface should take priority when displayed odds or requirements differ.
Reserve at least one copy of unusual traited or mutated monsters until you have compared their breeding value, activity performance, and evolution potential.
Q: What are catch a monster traits?
Traits are special modifiers that can appear on caught, hatched, or bred monsters. They are separate from elements, ranks, mutations, evolutions, and base stats.
Q: Can two monsters without traits produce a traited offspring?
Yes, the described breeding system allows offspring to gain a newly discovered trait even when neither parent visibly has one. A parent with a trait is expected to improve the probability.
Q: Where do I breed monsters?
Use the nursery located in a side area of Skyheart Island. The breeding panel lets you select the male and female parents and begin the timer.
Q: How can I reroll an evolution multiplier?
For bred pets, use a Chaos Potion to reveal or reroll the evolution multiplier. Inspect the result carefully before replacing a value you already like.
