You’ve finished Tenna’s section, heard about the Shadow Mantle, and now you’re wondering where the heck it is.
You didn’t miss a normal chest.
The Shadow Mantle is tied to Chapter 3’s Sword Route, which sends you into the strange Original Game hidden backstage in the Green Room. You’ll have to clear multiple hidden game boards, grab the Ice Key, find the White Cloak, work through the Ice Palace, collect the Shelter Key, and finally face the Shadow Mantle holder.
And yes, this whole thing gets increasingly creepy the deeper you go.
The reward is worth it, though. The Shadow Mantle is an armor piece that gives defense equal to the current chapter number and greatly reduces Dark/Star damage. In Chapter 3, it starts at +3 DF and provides a 66% reduction against Dark/Star damage. That makes it especially useful against the Roaring Knight, Chapter 3’s Shadow Crystal boss. It is extremely helpful, but it is not strictly mandatory to defeat the Knight.
Here’s the complete route from the first rank requirement to the Mantle itself.
Where Can I Find the Shadow Mantle? (Quick Answer)
Already know what you’re doing and just want the route sitting on your second monitor while you play?
Follow this progression:
- Qualify for the Original Game after Round 1 of TV Time with an S, T, or Z Rank, or use a counterfeit S-Rank where available.
- Enter the Green Room backstage and start the Original Game.
- Clear the first Desert Board and obtain the Ice Key.
- Qualify for the next Original Game board after Round 2.
- Reach the northern icy area of the Island Board and use the Ice Key to enter the Ice Palace.
- Find the White Cloak and use her ice attack to solve the dungeon puzzles.
- Follow the White Cloak through the maze.
- Use the Ice Key at the final door and continue through the black rooms to obtain the Shelter Key.
- Return to the Original Game after Round 3 and enter the City Board’s manhole dungeon.
- Defeat the Shadow Mantle holder.
- Have Kris collect the Shadow Mantle from the chest.
The important part is that this is a multi-round route. You don’t simply beat Tenna and find the armor waiting in your inventory.
Do You Need S Rank to Get the Shadow Mantle?
No. S Rank is not the only way into the Sword Route.
This is one place where older guides and Reddit discussions can make the route sound stricter than it actually is. Current documentation shows that the Original Game can be accessed after the relevant TV Time round with an S Rank, T Rank, or Z Rank. There is also a counterfeit S-Rank option that costs 1500 POINTs.
The Reddit guides you shared focus heavily on getting S Rank because it is the straightforward approach, and players in the discussions commonly recommend aiming for strong scores, all four keys/photos, and the physical challenge bonuses. But the game’s actual rank system is based on a combined evaluation rather than one single “get these exact things or you fail” checklist.
Tenna’s Minigame S-Rank Guide
If you want the cleanest route, getting the required high rank is still a good approach.
For the boards, pay attention to the things that contribute to your overall evaluation:
- POINTs earned
- Your performance in the board’s battles
- The relevant physical challenge
- Secret bonuses such as the extra key, extra photo, and moss
The Reddit Shadow Crystal guide specifically recommends pushing for around 1500 POINTs, finding all four keys, and playing the Cooking Minigame carefully on the first board. For the second board, it recommends collecting the four photos, eating the moss, and performing well in the rhythm section. Treat those as practical player tips rather than a literal universal S-Rank checklist.
Can You Get the Shadow Mantle Without S Rank?
Yes.
There are a couple of different ways to qualify for the hidden sequence.
Use T Rank or Z Rank
Current route documentation confirms that T Rank and Z Rank can also provide access to the Original Game. The Z-Rank path has its own route into backstage rather than simply being identical to the S-Rank-room path.
Buy the Counterfeit S-Rank
If you land on A, B, or C Rank, a Pippins in the red carpet hall can offer a counterfeit S-Rank for 1500 POINTs. This gives you another way to access the route without having to replay the board until you finally nail the ranking.
There is one useful catch from the game’s progression rules: the Pippins does not simply appear whenever you want. After Round 2, the Pippins only appears if you had a real or counterfeit S Rank from Round 1. A Z Rank does not make the Pippins sell you a counterfeit S Rank.
Tip: If you already have the rank you need, don’t spend 1500 POINTs just because the Pippins is standing there. The Reddit guide specifically recommends keeping the counterfeit option in mind as a backup if you still need access later.
How to Access the Shadow Mantle Secret Room
Once you qualify for the route, head back to the Green Room and look for the changing-room/backstage area.
In the S-Rank changing room, Ramb guards the old double-brown door and explains that the game Tenna has been showing isn’t the original version. The backstage area contains the Original Game and the console needed to start it.
Inside backstage, you’ll find:
- The employee controller area
- The abandoned game system
- The missing controller situation
- The OddController that Kris needs to use to start the Original Game
Once you plug in the controller, the hidden game begins.
Why Is the Shadow Mantle Door Locked?
This is one of the questions that comes up repeatedly in the Reddit discussions.
The important thing is that the Sword Route is sequential.
You can’t simply walk backstage and skip to the Shadow Mantle fight.
You need to complete the relevant Original Game stage, return for the next one after the next TV Time round, and continue the route in order. The Green Room also changes as the rounds progress, so a locked backstage door can mean you’re trying to access the wrong stage or that you haven’t obtained the required earlier item.
Complete the First Secret Minigame — The Sword Route
This is where the Original Game starts feeling less like a normal minigame and more like someone stuffed a weird old adventure game inside Deltarune.
The first board is the original version of the Desert Board.
You control HERO_SWORD rather than the normal party, and the enemies don’t behave like ordinary Deltarune encounters. You have an on-screen HP meter, and your goal is to become strong enough to cut through the obstacles blocking the rest of the map.
Get the Sword and Level Up
- Head to the former Secret Mailroom. The sword is waiting there.
- Pick up the sword.
- Kill the enemies on the board to increase HERO_SWORD’s LV.
- At LV 2, you can break ferns.
- At LV 3, you can destroy cacti.
- Continue defeating the accessible enemies until you reach LV MAX.
- At LV MAX, you gain the ability to cut the palm trees that keep you boxed into the normal board.
This LV progression matters because simply reaching Level 3 isn’t enough to finish the board. You need the higher strength from LV MAX to reach the area containing the Ice Key.
Find the Ice Key
Once you’re strong enough:
- Clear the cacti blocking the previously inaccessible cold-looking area.
- Keep defeating the enemies there.
- Reach LV MAX so you can cut the palm trees.
- Use the newly opened route to go out of bounds from the normal board.
- Continue through the strange tree-filled area.
- Eventually, you’ll reach a chest containing the Ice Key.
The moment you collect the Ice Key, the Original Game shuts off and Kris returns to the normal Chapter 3 progression.
Don’t leave without the Ice Key. The next board literally checks whether you brought it with you.
Use the Ice Key to Reach the Frozen Area
After the next round of TV Time, you can access the second Original Game stage as long as you’ve met the rank/access requirement for that round.
This time you’re on the Island Board.
And this one has a fun little trick: the map initially doesn’t let you simply walk straight toward the area you’re trying to reach.
Find the Raft and Head North
Start by getting the sword again and defeating enemies until you reach LV 2.
Then:
- Destroy the ferns blocking the waterfall.
- Ride the raft up the waterfall.
- Reach the upper section of the island.
- Find the raft near the northern area.
- Ride it toward the northwest.
- Continue into the cold area that Tenna keeps inaccessible during the normal version of the board.
- Leave the raft and approach the locked door marked with the Delta Rune.
If you don’t have the Ice Key, the game makes it very clear that you’re missing something important and the sequence cannot continue.
Enter the Ice Palace
Use the Ice Key on the locked door.
That takes you into the Ice Palace, which is the major dungeon of the second Sword Route stage. The entire place is built around the new ice-based mechanics and the unsettling parallel to Chapter 2’s Weird Route.
Get the White Cloak
The Ice Palace is where you meet the White Cloak.
And yes, this is the part where the game starts feeling really familiar in a slightly uncomfortable way.
The White Cloak is essentially an in-game representation of Noelle, and she follows HERO_SWORD through the rest of the dungeon. When you attack, she fires an ice projectile. That attack can freeze enemies that would otherwise be invulnerable, turning them into movable blocks for the dungeon puzzles.
The Reddit discussions picked up on this atmosphere too. Players repeatedly described the whole section as unsettling, especially because of its similarities to the Weird Route and Chapter 2’s Snowgrave material.
Use the White Cloak to Solve the Puzzles
The White Cloak isn’t just there for the creepy Noelle parallel.
You actually need her.
Use the ice projectiles to:
- Freeze enemies that can become blocks
- Push those frozen enemies onto pressure plates
- Open doors
- Freeze the blue bird blocking the later route
Once the bird is frozen, you can get into the maze section.
How to Solve the Shadow Mantle Maze
This is probably the part most likely to make you stop playing and start searching for a guide.
Don’t.
Well, actually, you’re already here, so go ahead.
The maze is an infinite loop of crossroads. Three exits send you back around, while only one path moves you forward. Luckily, the game gives you a walking hint.
Follow the White Cloak.
If she follows HERO_SWORD through a direction, that is the correct path.
If she stops at the exit, that path is wrong.
Turn around and try another one.
Exact Shadow Mantle Maze Solution
For players who don’t feel like testing the same crossroads over and over, the current documented sequence is:
Up → Up → Left → Right → Right → Down → Right
The final direction is Right. This is important because older/community walkthroughs have circulated different sequences. The White Cloak’s behavior is still the best in-game clue because it directly identifies the correct path.
Once you’ve solved it, you reach the next locked door.
Get the Shelter Key
After the maze, the route takes you into a series of strange black rooms.
At the final door:
- The Ice Key is used up.
- The White Cloak is also “USED UP” and disappears.
- HERO_SWORD continues into the black chamber.
- The Shadow Mantle holder starts talking directly to Kris.
- Eventually, you find the Shelter Key.
Once you collect the Shelter Key, the Original Game shuts off again.
This is a major progression checkpoint.
You now have what you need to reach the final Sword Route board.
Reach the Shadow Mantle Boss
After the next stage of TV Time, return to the Green Room.
This time, the backstage route can lead to the final part of the Original Game because you have already obtained the Shelter Key.
The final stage takes place in the City Board’s manhole dungeon. It is the final area of the Original Game and ends with the optional Shadow Mantle holder boss.
What Is ERAM in Deltarune?
You may see searches for “ERAM Deltarune” while looking up this fight.
One important clarification:
ERAM is the name of the music track that plays before the Shadow Mantle holder battle.
The boss itself is generally called the Shadow Mantle holder in current documentation, with its game-file identifier based on shadow_mantle. The actual battle music is BURNING EYES.
So if a guide calls the boss “ERAM,” that’s community terminology rather than the clearest name to use.
How to Beat the Shadow Mantle Holder
This fight is different from the normal Deltarune fights you’re used to.
You don’t have your usual battle menu and healing setup. You’re controlling HERO_SWORD inside the Original Game, and the Shadow Mantle holder attacks from above the board while you move between blocks to line up sword hits.
One of the most important things to understand is that consumables aren’t available during this fight, so don’t go in expecting to heal normally. FRIEND enemies in the later phase can drop healing items, but those drops aren’t guaranteed every time.
Phase 1: Orbs and Bombs
The holder opens with two main patterns:
- Sets of orbs arranged in a hexagonal pattern
- Bombs that spread outward into smaller wave-like bullets
Don’t chase the boss around the screen.
Focus on staying alive and finding the safe space between the patterns while looking for opportunities to connect your sword attack.
Phase 2: Charges and FRIENDs
The holder moves to the top and repeatedly charges HERO_SWORD, leaving a fire trail behind.
After that, the boss summons five FRIEND enemies.
This is your important healing opportunity. The FRIENDs move around the arena and can drop healing items when defeated.
So don’t ignore the summons.
See FRIENDs? Take care of them. They’re not just there to make the room more chaotic.
Phase 3: Mixed Attacks
The third phase starts combining pieces of the earlier patterns.
You’ll see variations of:
- The charging attack
- Bombs
- Orb patterns
- Bombs mixed into the orb sequence
This is where the fight starts testing whether you can recognize the patterns instead of reacting to every projectile individually.
Phase 4: The Final Attack Loop
The final phase brings out a large rotating beam/orb pattern, followed by the charging attack with additional cloaks that cannot be hit.
The charging pattern then loops until the holder’s HP is depleted. So don’t make the mistake of assuming that surviving the pattern will eventually end the encounter by itself.
You still need to land the required sword hits.
A Useful Trick for the Fight
The Shadow Mantle holder’s damage behavior isn’t a normal “my AT versus its DF” calculation.
The damage you deal changes based on how many times you’ve hit the holder during the attack cycle. In other words, mindlessly spamming hits isn’t always the best idea.
Take the safe openings.
Don’t throw away a good attempt because you wanted one extra hit.
The Reddit discussions reflect the same basic experience: players often go into the fight expecting it to behave more like a puzzle where surviving is enough, only to realize that this one actually requires them to finish the job.
How to Get the Shadow Mantle After Beating Tenna
This search is a little misleading because beating Tenna itself is not what awards the Shadow Mantle.
The Shadow Mantle belongs to the Sword Route, which unfolds across the Original Game boards between the TV Time rounds. You need to complete that hidden sequence and defeat the Shadow Mantle holder to get the armor.
So:
Beat Tenna ≠ automatically receive Shadow Mantle.
If you’re searching for the armor because you’ve just finished Tenna’s section, check your progression rather than assuming the game forgot to give you the item.
The real checklist is:
- Did you access the Original Game?
- Did you finish the first board?
- Did you actually collect the Ice Key?
- Did you finish the Island Board?
- Did you get the Shelter Key?
- Did you complete the final manhole dungeon?
- Did you defeat the Shadow Mantle holder?
If the answer to one of those is “no,” that’s where you need to continue.
How Do You Actually Claim the Shadow Mantle?
This final bit is easy to miss because HERO_SWORD can’t simply walk over and grab the reward.
After the Shadow Mantle holder is defeated, a chest containing the armor appears out of reach of HERO_SWORD.
HERO_SWORD leaves the game screen, and Kris enters the screen to collect the Shadow Mantle.
There’s also a useful inventory safeguard.
If Kris has no room for another armor item, the game creates a chest containing the Shadow Mantle at Ramb’s counter in the Green Room instead.
So you don’t need to panic if you finish the boss and the armor doesn’t immediately appear where you expected.
What Does the Shadow Mantle Do?
The Shadow Mantle is an armor item with two main benefits:
- Defense equal to the current Chapter number
- Strong Dark/Star damage resistance
In Chapter 3, that means +3 DF and a 66% reduction to Dark/Star damage under the normal elemental-resistance effect.
It is particularly useful against the Knight because many of the Knight’s attacks use the Dark/Star element.
The armor also has special interactions with some of the Knight’s attacks. For example, the Box Splitter slash is reduced to roughly one-third of the target’s max HP instead of dealing the much higher damage it normally would.
That’s why players spend so much time going after it.
Who Should You Equip the Shadow Mantle On?
The Shadow Mantle can be equipped to Kris, Susie, or Ralsei. It cannot be equipped to Noelle.
The Reddit discussions are split mainly between Susie and Kris, and there’s a good reason for both approaches.
Shadow Mantle on Susie
The argument for Susie is simple:
More HP + Shadow Mantle resistance = more room for mistakes.
Community players frequently recommend Susie when the goal is to make the Knight fight easier to survive. This lets you build the strategy around keeping Susie alive and using Rude Buster for damage while other turns are spent defending or supporting the party.
Shadow Mantle on Kris
The other approach is to put the Mantle on Kris.
The idea here is that Kris can remain alive as the party’s item user and support character, spending turns defending when needed and helping keep the team standing.
The Reddit guide you supplied specifically argues for Kris as a kind of TP battery and medic, while other players in the discussion report strong results with Susie.
So, Who Is Better?
There isn’t one universal answer.
Want the safer tank? Try Susie. Want Kris to stay alive and handle support? Use Kris.
The community debate itself is useful here because both setups have worked for players.
Does Getting the Shadow Mantle Affect the Pacifist Route?
The Sword Route can look alarming because the Original Game explicitly has HERO_SWORD defeating enemies, and the later sections deliberately echo the uncomfortable ideas from Chapter 2’s Weird Route.
But the Sword Route is its own Chapter 3 alternate route rather than simply continuing the Chapter 2 Weird Route. The Reddit discussions also repeatedly report that completing the Original Game did not destroy their recruitments or force the same type of route change associated with Snowgrave.
So, for players worried about a Pacifist-style run:
Obtaining the Shadow Mantle through the Sword Route does not automatically turn Chapter 3 into the Weird Route.
That said, the game clearly wants you to notice the parallels. The atmosphere is deliberately uncomfortable, and the White Cloak section is a big part of that.
Is There a Shadow Mantle Cheat in Deltarune?
There isn’t a normal console command or cheat code that you need to enter to spawn the armor.
The closest thing to a built-in shortcut is the counterfeit S-Rank sold by the Pippins for 1500 POINTs.
So when you see people searching for “Deltarune Shadow Mantle cheat,” the practical answer is:
You don’t need a cheat code. Use the game’s counterfeit S-Rank option if your rank isn’t high enough to access the route normally.
Can You Get the Shadow Mantle in Deltarune Chapter 4?
The Shadow Mantle is a Chapter 3 Sword Route reward.
There isn’t a separate Chapter 4 Shadow Mantle pickup that replaces the Chapter 3 route. Current item documentation still lists its source as the Sword Route, and Chapter 4’s Seam dialogue specifically treats the Mantle as something you either obtained during Chapter 3 or didn’t.
So if you’re already in Chapter 4 and wondering:
“Where do I find Shadow Mantle in Chapter 4?”
Don’t waste an hour searching the Chapter 4 areas for a new chest.
The armor comes from Chapter 3.
Shadow Mantle and the Shadow Crystal
This is where the whole thing starts making sense.
The Shadow Mantle is the reward from the Sword Route.
The Roaring Knight is Chapter 3’s Shadow Crystal boss. If you defeat the Knight, you receive the BlackShard and a Shadow Crystal. The Shadow Mantle makes that fight dramatically more manageable, but it does not make the battle mandatory or impossible without the armor.
So the progression is:
Sword Route → Shadow Mantle
then
Roaring Knight → BlackShard + Shadow Crystal
That’s an important distinction because the two encounters are connected, but they’re not the same reward path.
Common Shadow Mantle Problems
I Got A Rank Instead of S Rank
Don’t assume the run is over.
Depending on your rank and round, check the Pippins in the red carpet hall. For A, B, or C results, they can offer a counterfeit S-Rank for 1500 POINTs.
The Secret Door Won’t Open
You probably haven’t completed the required previous stage.
The Sword Route is sequential. You cannot skip straight to the final boss.
I Can’t Find the Ice Key
Keep leveling HERO_SWORD.
LV 3 lets you cut cacti, but the Ice Key route requires progressing to LV MAX so you can cut the palm trees and reach the out-of-bounds section where the chest is located.
I Can’t Solve the Maze
Stop guessing random directions.
Watch the White Cloak.
If she follows you, you’re going the right way. If she stops, turn around. The documented sequence is:
Up → Up → Left → Right → Right → Down → Right.
I Used the Ice Key but Still Can’t Continue
Make sure you actually completed the first Original Game stage and obtained the real Ice Key.
The Island Board checks for that item. Without it, the Ice Palace can’t be entered.
I Finished the Shadow Mantle Fight but Can’t Find the Armor
Check the chest after the fight and let Kris collect it.
If your armor inventory is full, look at Ramb’s counter in the Green Room for the replacement chest.
I Finished Chapter 3 Without Getting the Shadow Mantle
The important thing is that the Mantle is tied to the Chapter 3 Sword Route. It’s not a standard Chapter 4 item that you can simply pick up later in another area.
Frequently Asked Questions
How do you get the Shadow Mantle in Deltarune Chapter 3?
Complete the Sword Route through the Original Game, obtain the Ice Key, progress through the Ice Palace, collect the Shelter Key, complete the final manhole-dungeon stage, and defeat the Shadow Mantle holder.
How do you get Shadow Mantle armor in Deltarune?
You obtain the Shadow Mantle after defeating the Shadow Mantle holder at the end of the Sword Route. Kris then opens the chest containing the armor.
Where can I find a Shadow Mantle?
The final reward chest appears after the Shadow Mantle holder fight in the Original Game’s manhole dungeon. HERO_SWORD cannot reach the chest, so Kris collects it afterward.
Can you get the Shadow Mantle without S Rank?
Yes. S, T, and Z Rank can provide access to the relevant Original Game stages, and a counterfeit S-Rank can also be purchased for 1500 POINTs under the appropriate conditions.
How do you get the Shadow Mantle after beating Tenna?
Beating Tenna itself doesn’t award the armor. The Shadow Mantle comes from completing the separate Sword Route and defeating the Shadow Mantle holder.
Who should wear the Shadow Mantle?
The armor can go on Kris, Susie, or Ralsei. Community strategies often favor Susie for survivability or Kris for support and item use.
Does the Shadow Mantle affect a Pacifist run?
The Sword Route is a separate Chapter 3 route, and community testing indicates that completing the Original Game doesn’t automatically produce the Chapter 2-style Weird Route outcome.
Is there a Shadow Mantle cheat?
There is no normal cheat code required. The closest built-in shortcut is buying the counterfeit S-Rank for 1500 POINTs when the Pippins offers it.
Can you get the Shadow Mantle in Chapter 4?
The Shadow Mantle is a Chapter 3 Sword Route reward, not a new Chapter 4 pickup.
What is ERAM in Deltarune?
ERAM is the music track associated with the Shadow Mantle holder’s pre-battle sequence. The boss itself is referred to as the Shadow Mantle holder, while the actual battle uses the track BURNING EYES.
Final Takeaway
The Shadow Mantle is one of those Deltarune rewards that feels deliberately hidden.
You start with a normal TV minigame, sneak backstage, boot up an Original Game, pick up a sword, grind HERO_SWORD to LV MAX, escape the normal board, find the Ice Key, sail toward the frozen north, meet the White Cloak, follow her through a bizarre maze, find the Shelter Key, and eventually end up fighting the thing that’s been talking to Kris from the shadows.
And yes, by the time you finally get the armor, the game has made you work for it.
The clean route to remember is:
Qualifying Rank → Original Game → Sword → LV MAX → Ice Key → Island Board → Ice Palace → White Cloak → Maze → Shelter Key → Manhole Dungeon → Shadow Mantle holder → Shadow Mantle
Once you’ve got it, you’re ready to make the Roaring Knight fight considerably less painful—and you finally have the weird scrap of cloth Seam was talking about all the way back in Chapter 2.
