Slumber by Blossoms is the first 5-star Legendary outfit added to Infinity Nikki, introduced with the 2.5 update alongside the Boneyard region. It sits in a new rarity tier separate from Miracle Outfits, carries the Sweet attribute, and is permanently craftable rather than gated behind a limited banner.

Unlock requirements before crafting
The sketches sit inside the Itzaland Heart of Infinity, but they only appear once the 2.5 main story arc is wrapped up. The full set spans nine sketches, and unlocking each node costs Whimstars from across Miraland.
Step 1: Complete the version 2.5 main quest "Where All Souls Return." Finishing the quest line opens the Itzaland Heart of Infinity layout that contains the new outfit's sketches.
Step 2: Collect at least 25 Whimstars and spend them on every Slumber by Blossoms sketch node in the Heart of Infinity. Once all nine sketches are unlocked, the outfit becomes craftable in the wardrobe menu.
Step 3: Unlock the enhanced Animal Grooming, Plant Collection, and Bug-Catching essence nodes from the same Heart of Infinity tree. Several materials only drop after these upgraded gathering abilities are active.

Full material checklist
Crafting all nine pieces of the base outfit requires 21 distinct materials. Most come from the Boneyard, with two exceptions tied to weekly content (Mira Crown) and a Realm of the Dark challenge.
| Material | Quantity | Where to get it |
|---|---|---|
| Dreambloom of Yore | 12 | Glow Shop, bought with Sunny Shimmer from the Echoes of Tides Mira Crown Merit Arena |
| Nela Feather | 4 | Groom Nela birds (unlocked via "The Past of Dragons and You: Protection of the Newborn") |
| Candlemelt Cluster | 23 | Pick during daytime near Dragon Ruins, south of the Warp Spire |
| Candleglow Cluster | 15 | Same nodes as Candlemelt, but only at night |
| Boneflame Bloom | 26 | Dragonrest Flowerfield and other tracked points across the Boneyard |
| Windspin Flower | 2 | Scattered across the Boneyard map |
| Glimmerdrift | 12 | Hot spring pools by the Cultivarium Warp Spire, caught with the bug net |
| Sproutantler Fur Essence | 13 | Groom Sproutantlers (Dragon Ruins area) |
| Leafantler Fur Essence | 13 | Groom Leafantlers, usually paired with Sproutantlers |
| Candleglow Cluster Essence | 6 | Pick Candleglow Clusters with the essence node active |
| Terra Gem: Sweet | 110 | Phantom Trial: Esseling Pack (Stronghold) Realm of the Dark challenge |
| Plumeveil Feather | 15 | Groom Plumeveil birds near Lonestone Shore |
| Dragonspine Stem | 10 | Cultivarium area, trackable on the map |
| Glaciscale | 15 | Shoreline pickups near Lonestone Shore; also from Dig, Pear-Pal |

| Pearled Spider | 3 | One sits in front of Lonestone Shore Warp Spire; track the rest |
| Emberpaw Furball Essence | 8 | Groom Emberpaws in Cultivarium and Lonestone Shore |
| Umbrellabloom Essence | 12 | Pick Umbrellablooms along Boneyard shorelines |
| Dragonspine Stem Essence | 12 | Pick Dragonspine Stems with the essence node unlocked |

Time-gated materials to start first
Two materials drag out the timeline more than any of the open-world pickups, so it pays to begin them on day one.
Dreambloom of Yore comes exclusively from the new Mira Crown Merit Arena called Echoes of Tides. Clearing the arena awards Sunny Shimmer, which is then exchanged at the Glow Shop for Dreambloom of Yore. The exchange is capped per week, so the 12 needed for the full outfit will take multiple resets to collect, similar to how earlier Miracle Outfits were paced.
Terra Gem: Sweet drops from the Phantom Trial: Esseling Pack (Stronghold) inside the Realm of the Dark. Each clear consumes Vital Energy, and 110 is a sizable pile, so running it on cooldown alongside other farming activities is the fastest path.

Boneyard gathering routes
Most of the plant and animal materials cluster in three Warp Spire zones, which makes route planning straightforward.
Dragon Ruins: Candlemelt and Candleglow Clusters spawn in dense patches just south of the spire, along with Boneflame Bloom in the surrounding flowerfield. Sproutantlers and Leafantlers roam the same area in pairs, so a single grooming pass yields both essences.
Cultivarium: The hot springs near this spire host Glimmerdrifts, while Dragonspine Stems grow along the slopes leading away from it. Emberpaws also appear in this region for furball essence.
Lonestone Shore: The shoreline holds Glaciscale, Plumeveil birds, Umbrellabloom, Leatherbag Beetles, and Pearled Spiders. Bug-type materials here require the stealth approach from the bug-catching outfit; rushing in scares them off.
Nela birds are the one exception. Their habitat stays hidden until the random quest "The Past of Dragons and You: Protection of the Newborn" is completed, after which the grooming nodes appear on the map.

Evolutions and what crafting unlocks
The base outfit is only stage zero. Slumber by Blossoms evolves through three named stages and then a fully glowed-up form, with each step requiring additional resources on top of the base craft.
| Stage | Name | Unlocks |
|---|---|---|
| Base | Slumber by Blossoms | Outfit ability "Sacred Tree's Protection: Whimsicality" |
| Stage 1 | Slumber by Blossoms: Flourishing | Pose "Among the Blossoms" |
| Stage 2 | Slumber by Blossoms: Tidecall | Visual evolution of pieces |
| Stage 3 | Slumber by Blossoms: Evenfall | "Twilight Offering" makeup, new idle animation, additional poses, enhanced effects |
| Final | Slumber by Blossoms: Sunward | Full glow-up form |
The outfit's main attribute is Sweet, which makes it relevant for any Stylist Duel or Esseling encounter that scales off Sweet stats. Its ability, Sacred Tree's Protection: Whimsicality, is a passive light effect rather than a traversal tool, so it does not replace the role of Miracle Outfits like Wishful Aurosa or Floral Rebirth in the open world.

How to confirm the craft
Once every sketch is unlocked and the materials are in your bag, the wardrobe will mark each piece with a green craft icon. Selecting Craft consumes the materials and adds the piece to your collection immediately. The base outfit must be fully assembled before any evolution stage becomes available, and evolutions also require their own breakthrough materials, mirroring the structure used in version 2.0's Miracle Outfit.
Because Slumber by Blossoms is permanently available, there is no deadline pressure. Players who want a backup set for the final evolutions can farm overworld materials twice on the same routes, since plants and animals refresh on standard region timers.
