One of the most profoundly rewarding aspects of immersing oneself in the enchanting world of Deltarune is the intrinsic joy derived from systematically unlocking its myriad secret bosses and meticulously unraveling the intricate web of mysteries that lie concealed within its various realms. These clandestine pathways and challenging encounters are often only accessible to players who are willing to push past their perceived limits, meticulously exploring every concealed nook and cranny of the sprawling, imaginative maps. In the specific context of Chapter 3, every significant secret and hidden narrative thread appears to revolve intrinsically around your achieved ranks during Tenna’s highly anticipated and often bewildering game show.If your primary objective is simply to progress through and complete the chapter's main story arc without delving into the more intricate and hidden aspects, you are free to navigate each round of the game show, accept whatever rank you happen to achieve, and proceed onward. However, the ultimate accessibility of the chapter’s deepest secrets and its climactic hidden ending is entirely contingent upon your consistent and exceptional performance. This comprehensive guide will meticulously detail every step and requirement necessary to achieve that coveted full secret ending, guiding you through a series of demanding tasks and discoveries.

Deltarune : How to Get Chapter 3 Full Ending

To successfully unlock the coveted secret ending in Deltarune Chapter 3, players are tasked with the significant challenge of earning three individual S-ranks across the various rounds of Tenna’s game show. Each successive S-rank brings you progressively closer to gaining entry into a mysterious, enigmatic door prominently marked with an "S." Beyond this exclusive threshold lies a hidden single-player minigame, which, upon successful completion, generously rewards you with a series of special and utterly vital items. Here’s a breakdown of the crucial items you will acquire as you meticulously progress through these challenges:

Ice Key (obtained after achieving your first S-rank)
Shelter Key (obtained after achieving your second S-rank)
Shadow Mantle (obtained after achieving your third S-rank)

The first two keys are of paramount importance as they facilitate access to hidden areas that are integral to the secret ending. The culmination of acquiring these keys is the Shadow Mantle, a critical piece of equipment that you absolutely must equip if you harbor any hope of standing a chance against the chapter's ultimate secret boss, a powerful and enigmatic figure known only as The Knight.It is crucial to be fully prepared for an entirely solo endeavor: when you enter these secret minigames, you will be playing exclusively as Kris, alone. There will be no assistance from your trusted companions, Susie or Ralsei. It is solely your skill and determination against the challenges ahead, so ready yourself to handle every obstacle on your own.

How to Get Inside the S-Room

The pivotal S-room, which serves as the hub for all three clandestine minigames, is conveniently located within the Green Room. To gain entry, you have two primary options: either you must achieve an S-rank in a round of Tenna’s game show, which demands near-perfect performance; or, if you prefer to bypass the rigorous challenge of achieving an S-rank directly, you can opt for a more transactional approach by paying 1,500 points to the enigmatic Point Merchant. Once inside the exclusive S-room, you will discover three distinct portals, each serving as a gateway to a different solo challenge that Kris must confront and conquer independently.

How to Get the Ice Key

The very first secret minigame will reward you with the Ice Key, one of the three indispensable items required to unlock Deltarune's full secret ending. To successfully navigate this challenge, your journey begins by picking up a sword at the outset of the trial. Your objective is then to systematically defeat every single enemy you encounter within the area—be it the aquatic fish, the vibrant flowers, or the menacing purple monsters—to accumulate valuable EXP. It is essential to reach Level 4 to unlock the subsequent portion of the path forward.Once you have successfully leveled up, meticulously search for a concealed trail hidden behind a pair of twin cactus plants. You will need to use your sword to cut down any trees that obstruct your progression along this hidden route. At the very end of this secluded path, you will discover a treasure chest containing the coveted Ice Key. A crucial warning: ensure you do not miss a single enemy, as failing to defeat all foes will prevent you from both leveling up and opening the pathway forward.

How to Get the Shelter Key

In the second secret minigame, your reward upon completion will be the Shelter Key, an item vital for accessing a hidden shelter. This particular challenge shifts its focus from direct combat to the realms of puzzle-solving, careful navigation, and strategic traversal through intricate and often treacherous areas. While this minigame might be less about raw fighting prowess and more about intellectual dexterity and precise movement, the Shelter Key holds equal importance to the others in your pursuit of the ultimate secret ending.

How to Get the Shadow Mantle

The final and arguably most critical item you will need to acquire is the Shadow Mantle. This exceptionally powerful defensive garment provides crucialprotection, designed specifically to prevent you from being instantlydefeated during the climactic final battle. Possessing and equippingthis item is an absolute prerequisite if you intend to stand any chanceagainst the formidable secret boss, The Knight. To earn the Shadow Mantle, you must successfully complete the third and undoubtedly toughest minigame of the series, so prepare yourself for a truly rigorous challenge. Once you have managed to collect this invaluable item, along with thepreviously acquired Ice Key and Shelter Key, you will possess everything necessary to confront the final, most challenging part of the chapterand ultimately unlock its profound secret ending.

How to Use the Ice Key and Shelter Key

The Ice Key and Shelter Key each serve as unique catalysts, unlocking distinct hidden areas thatare of paramount importance for the secret ending's narrativeprogression. The Ice Key grants access to a frozen zone, an environmentrich with crucial story details and useful items that intricatelyconnect to the final segment of the chapter. Conversely, the Shelter Key provides entry into a quiet, secluded hidden area, which, uponexploration, reveals further insights into the deeper, more enigmaticmysteries woven into the overarching story of Deltarune.

Once you have thoroughly explored both of these newly accessible areas,return to the S-room and interact with the central structure to initiate the final sequence of events. Before proceeding, however, it isabsolutely imperative that you ensure Kris has the Shadow Mantle equipped; it is the sole means by which you can survive the impending climactic battle.

How to Beat The Knight

The ultimate adversary on this clandestine path is The Knight, a profoundly mysterious and immensely powerful figure whose existenceis intimately tied to the larger, unfolding narrative of Deltarune. This final battle is renowned for its extreme difficulty; without the crucial protection afforded by the Shadow Mantle equipped, you will be constantly at risk of being instantly defeated by The Knight's overwhelming attacks. The encounter itself ischaracterized by its blistering speed and a relentless barrage ofunpredictable attack patterns, demanding constant vigilance and agilereflexes from the player. Beyond the intense gameplay, this battle isalso densely packed with significant story content, providing new,revealing dialogue and an alternate ending that deepens yourunderstanding of the intricate world of Deltarune.

To even face The Knight, it is an absolute requirement that you havemeticulously collected all three key items (Ice Key, Shelter Key, Shadow Mantle) and, critically, are wearing the Shadow Mantle. Ensure that Kris is optimally prepared for survival, with a plentifulsupply of healing items and your most effective combat build.Successfully finishing all three preceding trials not only puts yourskills to the ultimate test but also irrevocably unlocks the full secret ending in Deltarune Chapter 3.
