Learn how to complete the Deltarune Weird Route from Chapter 2 to Side B. Follow all 19 required encounters, get the FreezeRing and ThornRing, and make the right choices to unlock Snowgrave without aborting the route.
Want to unlock the Weird Route in Deltarune? Widely known by the community as the Snowgrave Route, this hidden alternate storyline steers Noelle’s character development down a drastically darker path and unlocks several of the game’s most unsettling sequences.
However, you cannot trigger this path by simply attacking every enemy in sight. The Weird Route carries strict, specific requirements. You must utilize Noelle’s IceShock spell, backtrack through previous zones, acquire two critical rings, and pick exact dialogue options. Miss a mandatory encounter or select the wrong dialogue, and your route will be permanently aborted before you ever reach the defining SnowGrave battle.
This path officially initiates in Chapter 2, right after Noelle joins Kris’s party in Cyber City. From that exact moment, you are required to backtrack, freeze all necessary enemies, secure the FreezeRing and ThornRing, and ultimately force Noelle to cast SnowGrave on Berdly.
And that is just the beginning.
Your Chapter 2 save data carries this alternate narrative into subsequent chapters. Chapter 4 introduces a tense sequence involving Noelle’s bedroom, the SOUL, and precise conversational choices. Chapter 5 pushes the envelope further with an eerie lake sequence culminating in the INSERT CHAPTER 7 SIDE B screen.
This comprehensive walkthrough details the complete progression from your very first IceShock to the latest chapter-specific alternate endings. You will find actionable battle strategies, mandatory dialogue paths, route-abort warnings, and deep dives into the game’s hidden mechanics. Whether you are tackling Snowgrave for the first time or trying to salvage a run that failed, follow these instructions chronologically.
Spoiler Warning: This guide contains major story spoilers for Deltarune Chapters 2, 3, 4, and 5, including the Snowgrave encounter, Noelle’s alternate storyline, and the Side B sequence.
Quick Answer: How to Start the Deltarune Weird Route
The Weird Route activates in Chapter 2, specifically the moment Noelle joins Kris’s party in Cyber City.
Here is the entire route at a glance:
- Backtrack toward Spamton’s shop immediately after Noelle joins your party.
- Cast Noelle’s IceShock to freeze every required enemy encounter.
- Locate the hidden Poppup and finish all additional encounters in the Trash Zone.
- Speak with the Addison by the Ferris wheel poster and choose “We’re something else.”
- Acquire the FreezeRing by repeatedly pressing “Get it.”
- Complete the initial forcefield puzzle and choose Proceed at every route-specific dialogue prompt.
- Freeze all remaining enemies and buy the ThornRing from Spamton for 1,997 Kromer.
- Equip the ThornRing on Noelle, then cast SnowGrave on Berdly.
- Carry your Chapter 2 completion save file through Chapter 3.
- Navigate the special SOUL and Noelle’s Room sequence in Chapter 4.
- Advance the alternate story in Chapter 5, completing the timed lake sequence to trigger INSERT CHAPTER 7 SIDE B.
Quick Win: You do not need a special Chapter 1 save file. The Weird Route requirements strictly begin when Noelle joins you in Chapter 2. Start backtracking immediately and rely entirely on IceShock.
Approach this as a three-stage gauntlet rather than a single continuous boss run:
- Stage 1 (Chapter 2): Lock in the Snowgrave Route by freezing required enemies, acquiring the rings, and forcing Noelle to use SnowGrave against Berdly.
- Stage 2 (Chapters 3 & 4): Preserve your completion data, access Noelle’s house, and execute the SOUL sequence without letting Kris escape.
- Stage 3 (Chapter 5): Grab the Bread from Sans, navigate to the lake, and survive the timed Proceed prompt sequence.
Each stage operates under unique mechanics. While freezing Berdly is mandatory, it does not automatically beat the later chapters. You must deliberately maintain your save progression and approach every major interaction with the correct objective.
What is the Deltarune Weird Route?
The Weird Route (commonly dubbed the Snowgrave Route) is a hidden, alternate narrative path originating in Deltarune Chapter 2.
In a standard playthrough, Kris, Susie, and Noelle navigate Cyber City together. The Weird Route subverts this by centralizing Noelle’s ice magic. Instead of fighting normally, you systematically command Noelle to freeze enemies using IceShock. As you do this, she grows increasingly disturbed by Kris’s commands.
Eventually, the game introduces SnowGrave—a devastating ice spell that serves as the climax of the Chapter 2 alternate story. This route is not just a combat gimmick; your choices permanently alter character interactions, boss encounters, and future chapter sequences.
Why is it Called the Snowgrave Route?
SnowGrave is the ultimate spell linked to this alternate path. While Noelle starts by using IceShock, the route manipulates her into learning a fatal spell. Casting it against Berdly is the pivotal turning point of Chapter 2, leading the community to adopt Snowgrave as the route’s unofficial name. However, the Weird Route encompasses much more, extending its consequences well into later chapters.
Weird Route vs. Genocide Route: What’s the Difference?
Not exactly. While players frequently draw comparisons to Undertale’s Genocide Route, the Weird Route has vastly different mechanics. Randomly attacking enemies will not trigger it. You must utilize Noelle’s IceShock to land finishing blows and lock in specific choices during pivotal dialogue moments. The game monitors these precise actions, not your general aggression.
Important Note: Do not treat this like Undertale. Indiscriminate violence is not the trigger. Noelle, her IceShock spell, the designated encounters, and the required dialogue are the only things that matter.
This alternate storyline is carried forward strictly via your chapter completion data:
- Chapter 2: The original path begins via ice magic and the Berdly fight.
- Chapter 3: Past actions alter story references, though there are no new freezing requirements.
- Chapter 4: The narrative continues through a unique SOUL and ThornRing interaction in Noelle’s room.
- Chapter 5: Skips the standard Festival entirely, leading to the lake sequence and the Side B ending.
When Does the Snowgrave Route Actually Begin?
The route activates in Chapter 2, not Chapter 1. You are free to play Chapter 1 completely normally—there is no need to hoard EXP, avoid recruits, or select specific dialogue before reaching Cyber City.
The turning point occurs exactly when Noelle joins Kris’s party. From that second onward, your battle strategy must change. Instead of sparing or using standard attacks, you must rely on Noelle’s IceShock to freeze designated encounters.
If you fought or spared enemies before Noelle joined, your run is still safe. The game only tracks encounters from the moment she becomes a party member.
Exception: Sweet Cap’n Cakes. These musical robots constantly heal themselves, meaning you must defeat them using their specific ACT encounter. You cannot freeze them.
Pro Tip: If starting a fresh save file, just play Chapter 1 normally. Focus entirely on executing the correct Chapter 2 sequence once Noelle is in your party.
Essential Prep: What You Need Before Starting
Proper preparation will save your run. These prerequisites are easy to miss but vital for a smooth playthrough.
- Access to Chapter 2: You must reach Cyber City and progress until Noelle officially joins Kris’s party.
- Noelle Must Be in Your Party: The route hinges entirely on her IceShock spell, which must deliver the finishing blow to enemies.
- Keep a Separate Save File: Always save before initiating the Weird Route. A single wrong dialogue choice can permanently abort your Chapter 2 attempt. A separate save file is a vital safety net.
- Keep Enough Weapon-Inventory Space: Before riding the roller coaster in Chapter 2, ensure Kris has a minimum of two free weapon-inventory slots. You need physical space to hold both the FreezeRing and the ThornRing (reserve a third slot if you want the BounceBlade). If your inventory is full, the rings can disappear, permanently breaking your route.
- Understand the IceShock Requirement: Required enemies must be frozen with Noelle’s IceShock. While you can chip away their health with Kris, Noelle’s magic must land the final hit.
- Pay Attention to Dialogue: Selecting a friendly or dismissive response during key interactions can instantly abort the route, even if your combat execution was flawless.
Expert Insight: Flawless combat is not enough. Inventory management, dialogue choices, and save-file continuity are equally mandatory to keep the Snowgrave run alive.
Chapter 2 Weird Route Walkthrough: Initiating Snowgrave
If this is your first attempt at the Snowgrave Route, follow these steps to the letter. Once Noelle joins you in Cyber City, your first task is to backtrack and freeze specific enemies before advancing the main plot.
Step 1: Backtrack Immediately After Noelle Joins
Do not proceed to the next story objective. Turn around and walk backward through Cyber City all the way to the Trash Zone. You are looking for enemies that spawned before Noelle joined your party.
- Head backward through the zones you just explored.
- Return toward where your party initially landed after separating from Susie and Ralsei.
- Track down the enemies that spawned along this path.
- Freeze them using Noelle’s IceShock.
- Keep backtracking until you reach Spamton’s shop.
Backtracking is mandatory. The Weird Route alters the enemy spawns, and several earlier Trash Zone enemies are now required targets.
Step 2: Freeze All Required Enemies with IceShock
During every encounter on this route, Noelle’s IceShock must deal the final blow.
- Command Kris to Defend (this builds TP).
- Command Noelle to cast IceShock.
- Ensure IceShock depletes the enemy’s final HP.
- Repeat for all required battles.
Warning: Never spare enemies or use Sleep Mist. Doing so aborts the route instantly. Chapter 2 requires you to freeze all enemies across 19 encounters prior to the second Berdly battle.
Pro Tip: Have Kris constantly Defend to build TP. Do not let Kris accidentally kill an enemy with a standard attack.
Step 3: Locate and Freeze the Hidden Poppup
While backtracking through the Trash Zone, look for a standard traffic cone near the Cyber City entrance. This is actually a disguised Poppup. Approach it to trigger the fight, and freeze it with IceShock.
Check all surrounding Trash Zone rooms to ensure no newly spawned enemies are left behind. If you simply walk the main path, you will likely miss this hidden encounter.
Step 4: Listen for the Audio Confirmation Jingles
The game provides audio cues to confirm your progress.
| Audio Indicator | Meaning |
| Lower-pitched jingle | Successful route progression after certain actions. |
| Higher-pitched cancellation jingle | The Weird Route has been aborted. |
These audio cues trigger at major milestones, not after every single enemy. If you hear the high-pitched jingle, immediately reload your save.
Step 5: Clear Cyber City Traffic and New Enemies
As you freeze enemies, the overworld alters. Trashy and Nubert vanish. The standard cars in Cyber City are replaced by Ambyu-Lance and Tasque encounters. Later, near the Ferris wheel poster, cars are replaced by Virovirokun and Werewire enemies. The traffic buttons will also vanish as the posts freeze over.
Step 6: Trigger the Ferris Wheel Billboard Dialogue (Optional)
Interacting with the Ferris wheel billboard gives you alternate, unsettling dialogue options (“Noelle will ride with me” or “Sorry”). While this interaction highlights Noelle’s changing demeanor, it is strictly optional and will not break your route if skipped.
Step 7: Force the Addison to Hand Over the FreezeRing
Find the Addison selling Dating Shoes near the Ferris wheel billboard room.
- When asked about your relationship with Noelle, select “We’re something else.”
- When offered the FreezeRing, select “Get it.”
- Repeatedly select “Get it” through all prompts.
The Addison demands one Dark Dollar more than you currently own. By forcing the interaction, Noelle freezes the Addison to take the ring. Selecting “We’re friends” or refusing the ring will abort your run.
Step 8: Solve the First Forcefield Puzzle for Alternate Dialogue
Do not complete the first forcefield puzzle until after securing the FreezeRing. With the ring in your inventory, the puzzle cutscene changes. Noelle will express guilt about almost electrocuting Kris.
When prompted, select either “It’s horrible” or “It’s natural.” Both keep the route alive.
Step 9: Verify Remaining Encounters at Spamton’s Dumpster
Progress to the dog dumpster. The Annoying Dog is gone; Spamton is inside instead. Interact with him to check your remaining encounters. If you have followed the guide, he should display 4 LEFT.
This number tracks encounters, not individual enemies. If Spamton displays a higher number, you missed a battle. Backtrack immediately.
Step 10: Command Noelle to “Proceed” at the Mouse Puzzles
When you reach Annoying Mouse Room 2, Noelle asks how to solve the puzzle. You must select: “Proceed.” Do not select “Let’s solve it together!” or “Sorry, I’ll do the puzzle.”
Keep selecting Proceed until Noelle is frightened enough to freeze the puzzle herself. She will also independently freeze the third mouse puzzle. Make sure to catch the two overworld Maus encounters and the second Poppup encounter before the Berdly fight.
Step 11: Buy the ThornRing from Spamton and Equip It
Return to Spamton’s dumpster once all enemies are frozen. You can now purchase the ThornRing for 1,997 Kromer. Equip it on Noelle immediately.
| Ring | Effects and Purpose |
| FreezeRing | +4 Attack and +4 Magic. Helps Noelle freeze standard enemies easier. |
| ThornRing | +14 Attack and +12 Magic. Halves the TP cost of ice spells. Required to cast SnowGrave. |
Warning: The ThornRing causes Noelle’s HP to drain down to roughly one-third of her maximum in battle.
Pro Tip: Transfer Noelle’s strongest armor (like the Queen Pin) to Kris before the upcoming Berdly fight, as Kris will need it for a later solo boss battle.
Step 12: Force Noelle to Cast SnowGrave on Berdly
Ensure the ThornRing is equipped. Once the second Berdly battle initiates, Noelle gains access to SnowGrave. She will claim she doesn’t know the spell. Ignore her protests and repeatedly command her to cast SnowGrave.
Because the ThornRing halves spell costs, SnowGrave now costs 100% TP instead of 200%. Use the Wake ACT to boost Noelle’s Magic by 3 while building TP. Once cast, Berdly is permanently encased in a prism of ice. The Weird Route is now officially locked in for Chapter 2.
Step 13: Prepare Kris for the Solo Spamton NEO Boss Fight
With Berdly frozen, Noelle leaves the party. Queen goes missing, paths are blocked, and Kris must navigate an altered Queen’s Mansion alone via a manhole. Because Kris has no party members, you will fight Spamton NEO completely solo. Equip your best defensive gear and stock up on premium healing items.
Chapter 3 Weird Route Walkthrough: Bridging Your Save Data
Chapter 3 does not feature a separate freezing challenge. However, you must carefully bridge your save data to keep the route alive for Chapter 4.
- Complete Chapter 2 with SnowGrave successfully cast on Berdly.
- Return to the main menu.
- Use the Chapter 2 Files option to transfer your completion data.
- Start Chapter 3 using this transferred save.
- Play Chapter 3 normally to completion.
- Transfer this specific Chapter 3 progression into Chapter 4.
Important Note: You do not need to complete the optional Chapter 3 Sword Route to maintain your Weird Route save.
Chapter 4 Weird Route Walkthrough: The SOUL Sequence
Chapter 4 trades combat requirements for precise SOUL positioning and dialogue choices.
Step 1: Load the Correct Chapter 3 Completion Save
Ensure you load the correct Chapter 3 completion data. Play through Chapter 4 normally until the study session begins. You will notice a story divergence: Noelle receives a phone call from her mother instead of Berdly.
Step 2: Navigate the Vents to Noelle’s Bedroom
When Kris and the SOUL separate, Noelle will ask Kris to enter her room. Ignore standard progression. Take control of the SOUL, push the large box in the gift room, and navigate through the ventilation system until you reach the vent overlooking Noelle’s bedroom.
Step 3: Select “Proceed” and Move the SOUL into Kris
When the dialogue prompt appears at the vent, select Proceed. (Do not choose Please Don’t).
The SOUL will drop into the dialogue box area. You must manually move the SOUL into Kris’s body immediately. If you hesitate, Kris will grab Noelle and flee the room, permanently aborting the sequence.
Step 4: Lock in the Four Mandatory Dialogue Choices
Once reunited with the SOUL, Noelle will question the strange voice from Chapter 2. You must confirm those events were real.
| Dialogue Situation | Correct Response |
| Noelle asks who else could be hearing the conversation | Me |
| Noelle asks whether the experience was a dream | Because it wasn’t a dream |
| Noelle questions how Kris knows | I heard |
| Noelle suggests it was a coincidence | It’s not a coincidence |
Warning: Dismissing her experience as a dream or a prank aborts the route instantly.
Step 5: Complete the Ominous ThornRing Cutscene
Noelle will receive another phone call from her mother. Follow the prompts, confirming “It happened” and “It snowed” when Noelle tests you.
Kris will eventually be prompted to prepare a ring.
- Select Equip.
- When Noelle asks if it is the ThornRing, select Proceed.
- Select Proceed as Kris crawls forward.
- When Kris grabs Noelle’s wrist, select Equip again.
Kris forces the ThornRing onto Noelle, triggering a red crack across the screen and locking in the Chapter 4 Weird Route.
Step 6: Verify Success via Kris’s 10 HP Stat Drop
The game cuts to the bathroom. Kris violently throws the SOUL into the trash can and kicks it repeatedly until Asgore interrupts. Once Kris retrieves the SOUL and walks outside, check your stats: Kris’s maximum HP is now permanently reduced to 10 HP (down from 20 HP). This is your ultimate confirmation.
Step 7: Ignore Optional Enemies and Non-Essential Choices
Do not waste time trying to freeze every Chapter 4 enemy or forcing the Tenna rain scene. The Weird Route in Chapter 4 relies exclusively on the Noelle’s Room sequence. While defeating Titan Spawn or praying at the candles changes minor scenes, they are not mandatory for route continuation.
Chapter 5 Weird Route Walkthrough: The Lake and Side B
Chapter 5 bypasses the Flower Kingdom Festival completely, steering Kris and Noelle toward an eerie lake sequence.
Step 1: Load Your 10 HP Chapter 4 Save File
You must load the Chapter 4 save file where Kris’s HP was reduced to 10.
Step 2: Force Kris Out of Bed Manually
Kris refuses to leave bed normally. You must repeatedly input directional movement commands to force Kris to stand up. Once out of bed, leave the house.
Step 3: Meet Susie and Obtain the Bread from Sans
Meet Susie, who says Noelle is waiting at the lake. Before heading there, speak to Sans at his ice cream stand to acquire the Bread. Susie will block access to the lake if you skip this mandatory interaction.
Step 4: Rendezvous with Noelle at the Lake
Once at the lake, you will enter a conversation with Noelle that rapidly turns disturbing. Do not proceed into the lake room until you are completely ready, as you cannot leave once you enter.
Step 5: Survive the 74-Prompt Timed “Proceed” Sequence
As Kris and Noelle wade deeper, the screen shakes, visual distortion increases, and the textbox border turns red. You must navigate a massive 74-prompt dialogue sequence.
- First Stage (13 Prompts): The first six prompts allow you to pick Stop or Proceed safely. From the seventh prompt onward, only Proceed is available.
- Second Stage (61 Timed Prompts): Once their faces are submerged, a hidden timer activates. You must select Proceed 61 times in rapid succession. The timer duration shrinks with every click. If the screen fades entirely to white and static overtakes the audio, you have failed the sequence.
Step 6: Unlock the “INSERT CHAPTER 7 SIDE B” Ending
If you survive the timed prompts, a black CRT television screen appears displaying INSERT CHAPTER 7 SIDE B. The game will generate a unique Chapter 5 completion file with a _b suffix. This is the ultimate ending of the currently available Weird Route.
Common Mistakes: Why Does the Weird Route Abort?
It is incredibly easy to accidentally abort this run. Use this checklist to understand where things go wrong:
| Mistake | Why It Causes Problems |
| Attacking enemies randomly in Chapter 1 | The route-specific requirements haven’t started. |
| Finishing required encounters with Kris’s attacks | IceShock must deliver the final blow. |
| Sparing required enemies in Chapter 2 | Aborts the original route. |
| Using Noelle’s Sleep Mist on required enemies | Aborts the route. |
| Missing the hidden Poppup | Leaves a required encounter incomplete. |
| Choosing “We’re friends” at the Addison | Aborts progression. |
| Refusing the FreezeRing | Breaks the required interaction. |
| Completing the first forcefield puzzle too early | Prevents the required FreezeRing progression. |
| Choosing the wrong response instead of Proceed | Can break route progression. |
| Forgetting the ThornRing | Prevents Noelle from casting SnowGrave. |
| Defeating Berdly without SnowGrave | Aborts the Chapter 2 route. |
| Failing to move the SOUL into Kris | Aborts the Chapter 4 continuation. |
| Choosing that the Chapter 2 events were a dream | Causes Kris to grab Noelle and leave. |
| Choosing dialogue that treats the experience as a prank | Can break the Chapter 4 sequence. |
| Stopping Proceed during the submerged Chapter 5 sequence | Prevents the intended Side B completion. |
Important Note: If you accidentally abort the route, do not keep playing. Reload an older save immediately.
Weird Route vs. Normal Route: What Changes?
Should you do the Weird Route? Here is how it fundamentally changes the game:
| Feature | Normal Route | Weird Route |
| Noelle’s role | Normal party progression | Forced use of her ice magic |
| Chapter 2 encounters | Normal battles and puzzles | Required freezing encounters |
| Berdly encounter | Standard confrontation | SnowGrave encounter |
| Chapter 3 | Standard progression | Minor story and dialogue changes |
| Chapter 4 | Normal Noelle interactions | Special SOUL and ThornRing sequence |
| Chapter 5 opening | Festival progression | Kris sleeps through the Festival |
| Chapter 5 storyline | Flower Kingdom Dark World | Special lake sequence |
| Chapter 5 completion | Normal chapter progression | INSERT CHAPTER 7 SIDE B |
Additionally, you permanently lose the ability to recruit the following Cyber World enemies to your Castle Town: Poppup, Virovirokun, Werewire, Tasque, Ambyu-Lance, and Maus.
Deltarune Weird Route FAQ
Does the Weird Route Start in Chapter 1 or Chapter 2? It starts in Chapter 2 when Noelle joins Kris’s party. Chapter 1 actions do not matter.

Final Thoughts on the Snowgrave Route
The Deltarune Weird Route demands precision. In Chapter 2, you must freeze all 19 encounters, secure the FreezeRing and ThornRing, and cast SnowGrave on Berdly. In Chapter 4, you must manually pilot the SOUL and choose exact dialogue options to keep the narrative alive. Finally, Chapter 5 requires rapid reflexes during a 74-prompt timed sequence to unlock the SIDE B ending screen.
Do not treat this like a standard gaming challenge. Monitor your audio cues, check Spamton’s encounter counter, manage your rings, and always keep backup save files.
