- catch a monster mutations are farmed by catching mutated pets and extracting their mutation shards.
- Starter Island is a practical farming route because lower-rank pets are easier to catch and fuse.
- A-rank extraction provides nine shards, making rank fusion more efficient than dismantling low-rank pets.
- Special weather can improve mutation hunting, so check active servers before starting a long farming session.
- Mutation potions require 100 shards of the matching type before they can be crafted.
catch a monster Mutations: How the System Works
catch a monster mutations are special traits that can increase the value and combat potential of your pets. The main progression loop is straightforward: catch pets, identify mutated copies, raise their rank when worthwhile, and place them in the Mutation Extractor. Extraction converts the mutation into shards that can later be crafted into a potion.
The mutation types highlighted in current community testing include Shiny, Bloodlet, Huge, and Fairy. Each mutation has its own shard pool. For example, extracting a Shiny pet produces Shiny shards, while a Bloodlet pet produces Bloodlet shards. Keep each type separate when planning your next potion.

The main target is usually an A-rank mutated pet. According to the current extraction values, an A-rank pet gives nine shards of its mutation type. Lower ranks provide fewer shards, while S-rank and Double S-rank pets provide more. However, high-rank pets may be more valuable for your collection or combat team, so do not dismantle every rare pet automatically.
| Mutation | Example Use | Farming Priority |
|---|---|---|
| Shiny | Cosmetic value and mutation collection | High |
| Bloodlet | Mutation potion progression | High |
| Huge | Rare mutation target | Situational |
| Fairy | Rare mutation target | Situational |
Catch
Search for pets with visible mutations during normal farming. Keep mutated pets protected from accidental selling.
Fuse
Combine lower-rank pets when the shard increase justifies the required materials.
Extract
Use the Mutation Extractor to turn the finished pet into matching mutation shards.
Unlock a mutated pet before placing it in the Mutation Extractor, and double-check its rank before confirming the action. Rare mutations may be harder to replace than the shards they provide.
Best Farming Route for Mutated Pets
Starter Island is the most practical location for a low-cost mutation farming route. The method is not based only on mutation spawns. It also depends on catch consistency, easy access to lower-rank pets, and reduced use of limited fusion materials.
Starter Island is especially useful when you need ordinary C-rank and B-rank pets to upgrade a mutated catch. The route also supports daily and weekly progression tasks involving pet fusion. This makes the island useful even when mutation rates feel inconsistent.
| Farming Goal | Recommended Area | Main Reason |
|---|---|---|
| Catch many low-rank pets | Starter Island | Simple targets and efficient inventory cycling |
| Build fusion material | Starter Island | C-rank and B-rank pets are convenient for rank upgrades |
| Search during special weather | Any active server with the event | Special weather may increase mutation likelihood |
| Preserve rare resources | Starter Island | Lower-cost fusion path for routine quest progress |
Check the Server
Look for a server with a special weather event before committing to a long session. Community server listings can help you locate active weather, but event availability may change.
Travel to Starter Island
Begin farming on Starter Island and focus on catching a steady stream of pets. The goal is to generate mutated targets and ordinary fusion material at the same time.
Adjust Your Filters
Keep mutated pets and the ranks you need for fusion. Avoid filling your inventory with unnecessary normal pets when your immediate goal is mutation collection.
Fuse Selectively
Raise a useful mutated pet toward A rank when the material cost is reasonable. The commonly cited route uses four pets to create the next lower rank, followed by an Arcane Sparkstone for the B-to-A upgrade.
Extract or Keep
Extract the pet when the shard gain is more valuable than keeping it. Otherwise, lock it for your battle team, evolution plans, or collection.
The route works best when you treat mutation farming and quest completion as connected goals. A session that produces no exciting mutation can still provide fusion materials, task progress, and resources for later attempts.
Starter Island is a strong efficiency route, but current testing does not establish that it has the highest mutation spawn rate in every situation. Compare your results with other islands or locations when possible.
Mutation Extractor Ranks and Shard Values
The Mutation Extractor rewards higher-rank pets with more shards. The current values used for planning are simple enough to remember: E through B rank scale from one to four shards, A rank jumps to nine, S rank provides twelve, and Double S rank provides fifteen.
| Pet Rank | Shards Received | Recommended Action |
|---|---|---|
| E | 1 | Fuse first when materials are inexpensive |
| D | 2 | Usually continue ranking up |
| C | 3 | Useful as fusion material |
| B | 4 | Consider the cost of the next upgrade |
| A | 9 | Strong extraction target |
| S | 12 | Extract only if the pet is not needed |
| Double S | 15 | Usually preserve unless the mutation plan requires extraction |
The most efficient general target is an A-rank mutated pet. An E-rank mutated catch gives only one shard, while upgrading it to A rank can raise the return to nine shards. That difference matters because a mutation potion requires 100 matching shards.
At the same time, fusion costs must be controlled. Arcane Sparkstones are limited resources, and using them carelessly can slow other progression goals. The best choice depends on the pet’s rank, mutation rarity, your current shard total, and whether you need the pet for combat.
| Decision Point | Extract Now | Fuse Before Extracting |
|---|---|---|
| E- or D-rank mutation | Only if materials are unavailable | Usually better for common targets |
| C- or B-rank mutation | Consider if Sparkstones are scarce | Good when ordinary pets are abundant |
| A-rank mutation | Often efficient | Only if the pet has another purpose |
| S-rank mutation | Rarely automatic | Preserve if it supports your team |
| Double S mutation | Usually preserve | Extract only for a specific potion goal |
Use the following planning formula:
- Current shards: Count only the mutation type you want.
- Required total: Aim for 100 matching shards for the potion.
- Expected gain: Multiply the number of extracted pets by their rank value.
- Material cost: Include the ordinary pets and Sparkstones needed for fusion.
- Opportunity cost: Decide whether the pet is stronger as a team member than as a shard source.
A-rank mutated pets provide a large shard increase without requiring the higher investment associated with S-rank or Double S-rank progression. Use this rank as your default farming target.
Inventory Filters, Resources, and Session Setup
Good filtering prevents mutation farming from turning into inventory management. When the goal is to collect mutated pets, retain those pets and the ranks needed to fuse them. Normal low-rank pets can be useful later, but keeping every catch may reduce the space available for better targets.
A focused setup can use the following approach:
| Setting or Resource | Keep | Why It Matters |
|---|---|---|
| Mutated pets | Always keep until reviewed | They are the source of mutation shards |
| A-rank pets | Keep when useful | They may be extracted or used for progression |
| B- and C-rank pets | Keep during fusion sessions | They support rank upgrades |
| Arcane Sparkstones | Spend carefully | Needed for important rank fusion |
| S-rank pets | Review individually | Their combat and collection value may exceed shard value |
| Double S pets | Protect by default | They are difficult to replace and provide strong team value |
When you are actively collecting mutated pets, avoid selling the exact ranks required for fusion. A practical inventory cycle is to farm until you have enough ordinary pets, fuse the mutated targets, extract only the planned targets, and then resume catching.
The same resources can also support quest objectives. Current community testing identifies tasks involving fused A-rank pets and weekly rewards that include Reversion Potions. Reversion Potions may support evolution planning or be crafted into Chaos Potions, so completing these objectives can add value to a mutation session.
Mutation Storage
Keep every new mutation locked until you confirm its type, rank, and usefulness.
Fusion Materials
Save enough C-rank and B-rank pets before spending an Arcane Sparkstone.
Quest Progress
Combine mutation farming with daily and weekly fusion objectives when practical.
Team Review
Never extract a high-rank pet without checking its combat and evolution value.
First collect mutated pets and ordinary fusion material. Then stop catching, review your inventory, complete only the worthwhile fusions, and extract selected pets.

Q: What is the best way to farm catch a monster mutations?
Farm consistently in Starter Island, check for special weather events, keep mutated pets, and fuse lower-rank targets toward A rank before extraction when the resource cost is reasonable.
Q: How many shards does an A-rank mutated pet provide?
An A-rank mutated pet provides nine shards of its matching mutation type according to the current extraction values used in this guide.
Q: Should every mutated pet be dismantled?
No. Review the pet’s rank, mutation, combat value, evolution plans, and collection value first. S-rank and Double S-rank pets may be more useful as team members.
Q: Why does Starter Island help with mutation farming?
Starter Island supports steady catches, accessible lower-rank fusion material, and efficient progress toward fusion-related tasks. Its mutation rate should still be tested against other locations.
Prioritize the mutation type you are closest to completing, but preserve high-rank pets unless the potion progress clearly justifies extraction.
