Honkai: Star Rail — Minuscule Great Adventure Day 4 SS Rank Guide

Everwinter Hearth route bonuses, preset lineups, and the exact rewards for a 12-star clear.

Everwinter Hearth route bonuses, preset lineups, and the exact rewards for a 12-star clear.

Everwinter Hearth is the fourth and final stage of Minuscule Great Adventure, the combat assignment event running in Honkai: Star Rail 4.5. Like the three maps before it, the fight plays out as an auto-battle between paper standees on a stage, so the only real decision you make is which team goes down which route. Get the four lineups right and the stage hands you a full SS rating without you touching a single skill button.

Quick answer: Open Everwinter Hearth, load the Preset Lineup into all four routes, then press Skip in the top-right corner. The challenge resolves instantly at SS rank with 12 stars.


Before you enter Everwinter Hearth

The event sits in the Travel Log and needs Trailblaze Level 21 or higher. There are no Trailblaze Missions gating it, so if your account clears the level requirement, the entry is already there. Everwinter Hearth unlocks last in the stage list, after Imagenesis Park, Neon Dreamland, and Celestial Chess Array.

Minuscule Great Adventure runs from September 12 until September 28, 2026 at 03:59 (UTC+8), which is the deadline for claiming everything on the reward track. Before your first attempt, the Everwinter Hearth panel displays “No Data” instead of a rating, which is normal and simply means the stage has not been run yet.


Everwinter Hearth route bonuses and lineups

The stage splits into four routes, and each one carries its own combat bonus. Every route needs its own team, so you are filling sixteen slots in total. The bonuses reward very specific play patterns, which is why the presets pair each buff with a damage dealer that already works that way.

RouteBonusTeam
1Erudition BonusHimeko, Jade, Herta, Robin
2DoT BonusBlack Swan, Kafka, Guinaifen, Huohuo
3ATK Frequency BonusJade, Topaz & Numby, Aventurine, Robin
4Blood Bond BonusFirefly, Trailblazer (Harmony), Ruan Mei, Gallagher

Route 1 leans on Erudition units hitting the whole enemy board at once, so Himeko and Herta do the heavy lifting with Robin amplifying them. Route 2 is a straight damage-over-time package built around Kafka and Black Swan stacking effects that tick between turns. Route 3 wants as many extra actions as possible, which is why the follow-up attack core of Topaz & Numby, Jade, and Aventurine fits it. Route 4 runs the Firefly break team, with Ruan Mei and the Harmony Trailblazer pushing Break damage and Gallagher keeping the team alive.

If you do not own some of these characters, match the bonus rather than the name — an Erudition carry for route 1, your best DoT applier for route 2, a follow-up attack unit for route 3, and a Break-focused damage dealer for route 4.


How to clear Everwinter Hearth with SS rank

Open the Travel Log, select Minuscule Great Adventure, and press Go to enter the event hub. The four stages appear as separate cards along the map.
Pick Everwinter Hearth from the stage list. This is the fourth map and the last one to open up during the event.

On the Character Lineup screen, open the Preset Lineup menu and apply the saved teams to all four routes at once. This is far quicker than dragging sixteen characters in manually, and it stops you from accidentally leaving a route empty.
Confirm the four teams and press Start Challenge. The game moves straight into the stage performance with no loading into an actual battlefield.

Hit Skip in the top-right corner as soon as the battle starts. The whole simulation resolves in a second or two and drops you on the results screen.
Check the rating. A successful run shows an SS rating with 12 of 12 stars, and the Route 1 final stage data becomes viewable underneath. That rating is the confirmation you are done with the stage — there is nothing higher to chase.

What happens if you watch the full simulation

Skipping and watching are not identical. Letting the performance play out puts the standees on the theater stage with dialogue bubbles from Himeko, Black Swan, Jade, and Firefly, then rolls through four enemy waves in sequence.

Wave 1 ends almost immediately with zero cycles used, unlocking the Ace achievement. Wave 2 goes the same way and triggers Speed Determines the Victor.

Things tighten up after that. In wave 3, lineup 1 runs out of cycles and fails, though it still earns Gold Tier Support. Wave 4 is harsher still, with lineups 2, 3, and 4 falling to either team defeat or depleted cycles, while Speed Determines the Victor unlocks a second time.

That full watched run finishes at an S rating with 11 stars rather than 12. If your only goal is the reward track, skip the run.


Everwinter Hearth rewards for a 12-star clear

Rewards do not drop automatically at the results screen. Back out to the event rewards menu, find the Everwinter Hearth entry, and claim each tier, including the Adventure Grand Prize once the bar fills.

Across the whole event, the reward pool also includes Tracks of Destiny alongside the Stellar Jade, Relic Remains, Traveler’s Guides, Refined Aether, Lost Gold Fragments, and Credits handed out per stage. Once the Everwinter Hearth claim button turns grey and the stage shows SS, there is nothing left to farm here — the remaining rewards sit on the other three maps.

With all four stages cleared at 12 stars, the event is finished for the patch. The claim window stays open until the event closes on September 28, so anything you left unclaimed is still recoverable until then.
