A Universal Time Update 6.4 Guide: Halloween Event, New Codes, Items, and Bosses

A Universal Time (AUT) Update 6.4 introduces a brand-new Halloween event packed with quests, exclusive skins, bosses, emotes, and seasonal rewards. The map has also received a spooky makeover, with new locations such as the Witch’s Hut, a mysterious Sinkhole, and Hollow’s Garden inside the Knight’s Cavern.

The main activity in this update is Willow’s Halloween questline. Completing it unlocks the Event Ladder, Halloween Unusual Reroller, and access to additional boss content. Players can also collect event currency, hunt for rare items, and obtain several limited-time rewards. Here is a complete breakdown of everything added in A Universal Time Update 6.4.

A Universal Time Update 6.4 Halloween Event

The Halloween event brings several changes to the AUT map, giving different areas a darker and more mysterious appearance. Alongside the visual changes, players can discover new locations connected to the seasonal questline. Some of the important locations include:

• Witch’s Hut: The location where you can find Willow and begin the Halloween quest.
• Sinkhole: A mysterious area where Phantasm and Revenant enemies appear. It also provides access to Grim’s Arena.
• Hollow’s Garden: A new garden located inside the Knight’s Cavern, where players can find Hollow.
• Champion’s District: Ignis can be found near the large blue crack in this area.
• Sewers: A Certain Pumpkin is located at the end of the Sewers.

These locations are important because several NPCs and enemies are connected to Willow’s quest. You will need to visit multiple areas to collect the required crafting materials and eventually unlock the Halloween event rewards.

A Universal Time Update 6.4 Codes

Alongside the Halloween event, players can also redeem codes for additional rewards. Two codes are available from the information provided for Update 6.4. Here are the codes you can try:

• HEADSTART
• SORRY4DELAY

Make sure to enter each code exactly as shown because codes may be case-sensitive. If a code does not work, it may have expired or already been redeemed on your account. Remember to redeem available codes before they expire so you do not miss out on the rewards. Also check out our A Universal Time Codes for more rewards!

How to Complete Willow’s Halloween Quest

Willow is the main NPC for the Halloween event questline. You can find her inside the Witch’s Hut, and speaking with her will start the seasonal mission.

The quest requires you to meet several NPCs, complete their objectives, and collect three special items. These materials are used to craft the Hollow Lantern, which is required to progress toward the Grim boss fight.

Follow these steps to complete the quest:

1. Find Willow inside the Witch’s Hut and speak with her to start the Halloween quest.
2. Travel to Hollow’s Garden and talk to Hollow.
3. Complete Hollow’s quest, then speak with him again.
4. Return to Willow after Hollow directs you back to her.
5. Willow will ask you to collect three materials to craft the Hollow Lantern.
6. Visit Ignis and complete his quest to obtain the Hollowed Frame.
7. Find A Certain Pumpkin at the end of the Sewers and complete their quest to receive the Luminous Soul.
8. Speak with Kodama near the Witch’s Hut and finish the quest to obtain the Spectral Solvent.
9. Return to Willow with all three materials to receive the Hollow Lantern.
10. Follow Willow’s instructions and defeat Grim.
11. Return to Willow after defeating Grim to unlock the Event Ladder and Halloween Unusual Reroller.

There is one important detail regarding Kodama’s quest. Crafting the required item before accepting or progressing through the quest will not count toward its objective. You must follow the quest instructions and craft the required item at the correct stage.

After finishing the entire questline, you will gain access to the main Halloween progression system and additional event features.

How to Unlock the Event Ladder

The Event Ladder is one of the main reward systems introduced in Update 6.4. You can unlock it by completing Willow’s Halloween questline and defeating Grim.

Once available, you can deposit uE to progress through the ladder and claim exclusive Halloween rewards. This system gives players another way to spend their event currency while collecting seasonal items.

There is also a refresh mechanic. After completing one stage, you can refresh the ladder to receive another set of rewards. However, players should pay attention to the stages that provide uFragments.

The Event Ladder includes uFragments at these stages:

• Stage 3
• Stage 5
• Stage 7
• Stage 10

Since uE is also used for other Halloween activities, make sure to manage your event currency carefully before spending it on ladder progression or rerolls.

Halloween Unusual Reroller

Another reward unlocked through Willow’s quest is the Halloween Unusual Reroller. This feature allows players to spend uE to reroll the patterns attached to the new Halloween skins.

The reroller is especially useful if you want to customize the appearance of your seasonal skins. Instead of keeping the default pattern, you can use event currency to try obtaining a different variation.

However, using the reroller requires uE, so consider how much currency you want to reserve for the Event Ladder and other Halloween rewards.

Halloween Event Crates Return

Halloween Event Crates have returned in Update 6.4, giving players another opportunity to obtain items from previous Halloween events.

These crates contain exclusive rewards from older Halloween seasons. This means players who missed previous events can now try collecting some of those returning items.

The update also introduces new seasonal rewards, so there are more items to pursue this year. Since event currency is needed for multiple features, decide which crates and rewards you want to prioritize before spending your uE.

How to Get the Accursed Lantern Subpower

The Accursed Lantern is a seasonal limited-time Subpower added in the Halloween update. To obtain it, you need to complete Willow’s lantern-related quest and receive the Hollowed Lantern item.

After obtaining the lantern, you can use it to unlock the gates inside the Sinkhole. These gates reveal the path leading toward Grim’s Arena.

The lantern quest can also be repeated to obtain the subpower on multiple abilities. This is useful if you want to apply the Accursed Lantern to more than one ability.

Keep in mind that the Hollowed Lantern is not just a quest reward. It also plays an important role in exploring the Sinkhole and progressing through the Halloween content.

New Halloween Charms

Update 6.4 introduces four new charms that can appear on unusual skins. These charms are exclusive to Halloween-related reward sources, including Halloween Crates, Premium Reroll, and Willow’s Halloween Unusual Reroller.

The four new charms are:

• Charm 21 – Blood Moon: A new charm with a blood moon theme.
• Charm 22 – Pumpkins: Features a pumpkin-inspired design.
• Charm 23 – Horns: Adds a horn-themed appearance.
• Charm 24 – Hex: Introduces a mysterious hex-themed design.

These charms provide additional customization options for players collecting unusual skins during the Halloween event. Since they are tied to specific Halloween reward systems, you will need to use the available crates or reroll features to obtain them.

All New and Returning Halloween NPCs

Several NPCs have been added or made available as part of the Halloween event. Some provide quests, while others are enemies or bosses that players can fight for rewards.

Here is a breakdown of the important characters in Update 6.4.

Willow

Willow is an interactive NPC located inside the Witch’s Hut. She is the starting point for the Halloween questline and will guide you through the different objectives.

You need to return to her several times during the quest to receive instructions, submit materials, and unlock the Event Ladder.

Hollow

Hollow appears in two different forms during the event.

• Interactive Hollow: Located in Hollow’s Garden. You need to speak with him to progress through Willow’s quest. After unlocking the Event Ladder, talk to him again to gain access to his boss spawner.
• Hostile Hollow: Can be summoned through his unique boss spawner after meeting the required conditions.

To summon the hostile version, you must first unlock the Event Ladder, speak with the interactive Hollow, and obtain one Veilshard Fragment dropped by Grim.

Defeating Hollow provides several rewards, including event currency, a chance to obtain a Halloween kill effect, Hollow’s Scythe skin, and a Pumpkin.

Phantasm

Phantasm is a hostile enemy that appears inside the Sinkhole. You need to defeat these enemies to progress through the area.

Make sure to explore the Sinkhole after obtaining the Accursed Lantern, as it is connected to the path leading toward Grim’s Arena.

Revenant

Revenant is another hostile enemy found inside the Sinkhole. Unlike Phantasm, Revenant requires a special condition before it becomes vulnerable.

You must hit Revenant with the Accursed Lantern Subpower to make it vulnerable. Without using this ability, you will not be able to defeat it normally.

Ignis

Ignis is an interactive NPC located near the Champion’s District, right beside the large blue crack.

You need to complete his quest to receive the Hollowed Frame, which is one of the three materials required to craft the Hollow Lantern.

A Certain Pumpkin

A Certain Pumpkin can be found at the end of the Sewers. Speak with this NPC and complete their quest to obtain the Luminous Soul.

This is another required material for Willow’s lantern questline.

Kodama

Kodama is located near the Witch’s Hut and provides the final material needed for the Hollow Lantern.

Completing Kodama’s quest rewards you with the Spectral Solvent. Remember that crafting the required item before reaching the correct quest objective will not advance the mission.

Grim

Grim is the main Halloween boss and appears at the Sinkhole every 1.5 hours. Defeating this boss is required to finish Willow’s questline and unlock the Event Ladder.

Grim also drops several valuable rewards, including the Veilshard Fragment needed to summon Hollow.

Grim Boss Rewards and Drops

Grim is an important boss for Halloween event progression. Besides being part of Willow’s questline, defeating him provides event currency and several exclusive rewards.

The boss spawns every 1.5 hours at the Sinkhole, so players need to keep track of the spawn schedule if they want to participate.

Here are the available rewards:

• Event Currency: Guaranteed reward based on your damage ranking. Top attacker: 500 event currency. Second and third highest attackers: 400 each. Fourth and fifth highest attackers: 300 each.
• Random Halloween Skin: 85% chance, available only to the top three attackers.
• Grim’s Scythe Skin: 15% chance.
• Inhumane Spirit: 20% chance.
• Veilshard Fragment: 100% chance, but only rewarded to the top attacker.

The Veilshard Fragment is particularly important because it is required to summon Hollow. Since it is only given to the top attacker, you will need to secure the highest damage contribution if you want to obtain it from Grim.

Hollow Boss Rewards and Drops

After unlocking the Event Ladder and speaking with the interactive Hollow, you can summon his hostile version through the special boss spawner.

You need one Veilshard Fragment to start the fight. This item is dropped by Grim, making the two bosses connected through the Halloween progression system.

Defeating Hollow provides these rewards:

• Event Currency: Guaranteed reward based on your damage ranking. Top attacker: 250 event currency. Second and third highest attackers: 200 each. Fourth and fifth highest attackers: 150 each.
• Random Halloween Kill Effect: 85% chance, available only to the top three attackers.
• Hollow’s Scythe Skin: 15% chance.
• Pumpkin: 30% chance.

Unlike Grim’s fight, Hollow’s boss rewards include a random Halloween Kill Effect from the available Halloween Kill Effect Crate pool.

The Pumpkin is also useful for Shinigami progression, as it is one of the materials required for crafting.

All New Halloween Skins in Update 6.4

A Universal Time Update 6.4 adds several Halloween-themed skins for different abilities and characters. Many of these skins come with custom models, animations, sound effects, and recolored visual effects.

These skins offer plenty of new customization options for players. If you want to collect them all, check the Halloween boss drops, event crates, and Premium Store availability.

The new emotes include:

• Fright Funk

Each emote adds another option for character customization during the Halloween event.

New Titles in Update 6.4

Two new titles have been added as part of the Halloween event. Both are connected to the main questline and boss fight.

The available titles and their requirements are:

• Complete Willow’s Quest: Obtain by finishing Willow’s Halloween questline.
• Defeat Grim: Obtain by defeating the Grim boss.

These titles provide additional rewards for players who complete the main seasonal objectives.

New Halloween Achievement and Badge

A new achievement has also been added to AUT alongside the Halloween content. To unlock it, you need to complete Willow’s questline. This badge serves as proof that you have finished the main Halloween mission. Since the quest also unlocks the Event Ladder and Halloween Unusual Reroller, completing it should be one of your first priorities after entering the event.

A Universal Time Update 6.4 brings a large Halloween event with new quests, bosses, skins, emotes, charms, and exclusive items. Willow’s questline is the main starting point, as completing it unlocks the Event Ladder, Halloween Unusual Reroller, and access to more seasonal content.

After finishing the quest, you can continue fighting Grim and Hollow, collecting rare drops, and working toward the new Shinigami-related items. Make sure to manage your uE carefully because the Event Ladder, Halloween Crates, and Unusual Reroller all provide different rewards worth collecting.
