catch a monster void monsters: Where to Find Them

The three featured void monsters are tied to the event activity area on Skyheart Isle. They do not appear as ordinary overworld encounters. Instead, you must travel to the event area, use a Void Jar, defeat the monster that appears, and then attempt the capture.

This mechanic makes Void Jars the central resource for the entire hunt. A jar is not a capture item used after battle; it is the summoning tool that creates the encounter. Plan your inventory before traveling to Skyheart Isle so you can focus on the battle rather than returning to a shop after every attempt.

Video Highlights:

  • The update adds a Void Jar for summoning exclusive void encounters.
  • Noctane appears after the jar is successfully used in the event area.
  • Void monsters are stronger than their normal counterparts and have distinct coloration.
  • Capturing them can be difficult because their catch rate is very low.

The available update information identifies these as exclusive void monsters, not ordinary evolutions. Their unusual colors also help distinguish them from standard versions. The encounter system may rotate or expand with later updates, so check the in-game index after major event changes.

Best Starting Point

Go to the Skyheart Isle activity section first, then confirm that you have a Void Jar before attempting a summon. The jar is the key requirement for starting the encounter.

How to Get Void Jars and Frost Coins

Void Jars are listed among the event shop items and can also be purchased through the Spire Shop. The event currency associated with the update is Frost Coins, which can be earned through several activities rather than relying on a single farming route.

Rifts and dungeons are useful because they contribute to event progression while also giving you regular combat practice. Staying online throughout the day can provide additional Frost Worm Coins, according to the update details. Use these resources carefully because the event shop also contains the Fairy Vial and the core used for A-rank to S-rank fusion.

RiftsFrost Coins and combat rewardsCombine currency farming with battle practice
DungeonsFrost Coins and dungeon rewardsFarm while testing team strength
Online activityFrost Worm Coins over timePassive support for event progression
Spire ShopVoid Jars and fusion coresCheck when preparing for repeated attempts

The event shop creates a resource-choice problem. A Fairy Vial guarantees a Fairy mutation, while fusion cores support progression toward S-rank monsters. If your immediate goal is a void capture, prioritize enough currency for Void Jars before spending on secondary upgrades.

The update also introduces Nightmare difficulty in dungeons. It is described as close to Hard difficulty, but it can still be a useful option for players who already clear Hard consistently. Nightmare rewards include the green version of the dungeon slates, adding another reason to include dungeons in your farming cycle.

Resource Warning

Do not spend all of your Frost Coins on unrelated event items before deciding how many Void Jar attempts you want to make. Void monsters have a low catch rate, so one jar may not be enough.

Void Monster Spawn Route

Use this route whenever you want to make a focused attempt. It keeps the process simple and separates currency farming from the actual summon.

1

Gather Event Currency

Farm Frost Coins through rifts, dungeons, and available online activity rewards. Review the event and Spire Shops before spending so you know whether you need jars, healing supplies, or other progression items.

2

Obtain a Void Jar

Purchase a Void Jar from the available event shop or the Spire Shop. Treat each jar as an encounter attempt because the jar is consumed to summon a void monster.

3

Travel to Skyheart Isle

Enter the event area through the activity section on Skyheart Isle. Confirm that your team is ready before using the jar, since the summoned monster is stronger than its normal counterpart.

4

Use the Void Jar

Activate the Void Jar inside the event area. A void encounter, such as Noctane, will spawn in front of you after the item is successfully used.

5

Defeat and Attempt the Capture

Battle the monster, weaken it safely, and make your capture attempt. Because the catch rate is very low, preserve your best opportunity instead of rushing the encounter.

PhaseMain ObjectiveWhat to Check
PreparationBuild an attempt budgetFrost Coins, Void Jar, team strength
TravelReach the correct event areaSkyheart Isle activity section
SummonCreate the encounterVoid Jar activation
BattleDefeat the targetDamage control and survivability
CaptureSecure the monsterLow catch rate and remaining resources

The route is repeatable, but the result is not guaranteed. Avoid treating a failed capture as a progression error. The system is designed around repeated encounters, and a careful player can use each attempt to improve team damage, timing, and resource planning.

Efficient Loop

A strong routine is: farm rifts or dungeons, buy a Void Jar, travel to Skyheart Isle, complete one encounter, then return to farming only when your jar supply needs replenishing.

Battle and Capture Strategy

Void monsters are stronger than their normal counterparts, so the capture phase begins with team preparation. Your goal is not simply to defeat the target as quickly as possible. You also need to maintain control of the fight long enough to attempt the capture.

The supplied update details do not provide exact health values, damage values, or a guaranteed capture threshold for Noctane, Dusk Wing, or Luna Box. For that reason, use the following as practical priorities rather than fixed numerical requirements.

Team Readiness

  • Use a team that already handles your current dungeon difficulty.
  • Upgrade damage and survivability before spending several jars.
  • Avoid entering with a lineup that barely clears regular encounters.

Battle Control

  • Watch the target's health instead of relying only on burst damage.
  • Keep enough power available to finish safely if the encounter becomes difficult.
  • Do not sacrifice the entire team for a single rushed attempt.

Capture Discipline

  • Treat every Void Jar as a valuable attempt.
  • Make the capture attempt after establishing a safe battle position.
  • Expect multiple tries because the catch rate is very low.

Resource controlKeep spare currency for additional jarsThe catch rate is very low
Encounter focusTarget one void monster at a timeMakes progress easier to track
Visual confirmationCheck the unique coloration and index entryHelps confirm the correct variant

A player who already clears Hard dungeons should be in a better position to test Nightmare content and prepare for void encounters. However, dungeon performance is only a general readiness signal; it does not guarantee a successful capture.

The Catch a Monster Wiki index can be used as a reference for broader monster data, including listed elements, ranks, stats, and evolution markers: view the Catch a Monster monster index. The index reports a broader roster of 231 monsters, while the event update identifies three featured void exclusives. These figures describe different parts of the collection and should not be treated as the same category.

Before You Use a Void Jar:

  • Farm enough Frost Coins for another attempt if needed
  • Confirm that the Void Jar is in your inventory
  • Enter Skyheart Isle through the event activity area
  • Use a team that can handle stronger-than-normal encounters
  • Leave room in your collection for the captured monster
Index Check

After a successful capture, inspect your in-game index to verify the monster, its variant, and any newly recorded collection entry. The distinctive coloration is an immediate visual clue.

Event Progression and Related Rewards

Void monsters are only one part of the update. The same event introduces a Frost Evolution event, three event-exclusive pets, a new Dream Vale weather effect, and a Fairy mutation opportunity. These systems compete for time and currency, so choose a priority before beginning your farming session.

The Void Jar is the direct path to the void encounters. The Fairy Vial serves a different purpose by guaranteeing a Fairy mutation on one monster. The new fusion core supports the A-rank to S-rank system, which requires 10 copies of the same A-rank monster and 20 cores.

Nightmare dungeonsAccess to the new difficultyProvides stronger dungeon content and green slates

The update also lists new or newly relevant monsters such as Blaze Worm, Vine Worm, Avalanche Worm, Magma Tortoise, and Steam Forge. Avalanche Worm is described as a secret Frost Worm evolution requiring 16 Thunder Claw boss materials, two Water Gems, and 25 Ice Gems, with an approximately 17.08% chance of obtaining the secret evolution.

That evolution is separate from the void monster hunt. If your goal is collection completion, you may want to track both paths independently. If your goal is specifically Noctane, Dusk Wing, or Luna Box, focus your early event currency on Void Jars rather than fusion materials.

Choose One Priority

For collection hunters, maintain separate goals for void encounters, Frost Worm evolution, and S-rank fusion. Mixing every objective into one farming session can drain your event currency quickly.

Void Monsters FAQ

Q: Where do I find catch a monster void monsters?

Use the activity section in the Skyheart Isle event area. Void monsters are summoned with a Void Jar rather than found through ordinary overworld encounters.

Q: Which void monsters are available?

The update identifies three exclusive void monsters: Noctane, Dusk Wing, and Luna Box.

Q: How do I get a Void Jar?

Void Jars are available through the event shop and the Spire Shop. Frost Coins can be earned from rifts, dungeons, and online activity rewards.

Q: Why did my capture fail?

Void monsters have a very low catch rate, so a failed attempt is possible even after you defeat the target. Prepare additional jars and use a stable team for repeated attempts.

The most reliable approach is to treat every void encounter as a planned event attempt. Farm first, purchase the required jar, travel to Skyheart Isle, and enter the battle with enough strength to survive a longer capture sequence.

Final Recommendation

Start with Noctane, Dusk Wing, or Luna Box only after your team can handle stronger encounters consistently. Save your Frost Coins, repeat the route, and check the index after each successful capture.
