Every figure on this page comes from Valve, not from us and not from another wiki. It is re-read daily, and the two URLs at the bottom are the whole check — no key, no account, one request each. On PlayStation these are trophies, and the list is identical — same 46 entries, same names — but the grades, the platinum and a different rarity scale live on the trophy guide.

The completion drop-off

The scale is logarithmic: each labelled gridline is ten times rarer than the one above it. On a linear axis the bottom thirty rows all collapse onto the baseline, which is exactly the part of the curve worth reading.

First-party evidence

The Nushi roster, read off the shipped game

Seven internal ids begin ACH_NUSHI_. Six display names take the form “…’s End”. Both counts come straight out of the snapshot below, so the arithmetic is checkable without trusting this page.

This matters because of what it is not. Every other boss list for this game is either an extraction of a pre-release engine asset or somebody typing what they heard in a video. The achievement manifest is the shipped game’s own table, served by Valve. It is the closest thing to a primary source anyone covering this game has — and it puts the internal id and the localised name side by side in one place.

Internal idDisplay nameAnimal named by the idHow it was paired
ACH_NUSHI_SHIKARangifer's End
the fight →
Deer — 鹿 (shika)confirmed
Placed by the sync script with no judgement involved: this row's rank is currently unambiguous on both Steam endpoints. Rangifer is the reindeer genus.
ACH_NUSHI_SALAMANDERLacerta's End
the fight →
Salamanderconfirmed
Placed by the sync script with no judgement involved: this row's rank is currently unambiguous on both Steam endpoints. Lacerta is the lizard genus.
ACH_NUSHI_USHITaurus's End
the fight →
Ox — 牛 (ushi)confirmed
Placed by the sync script with no judgement involved: this row's rank is currently unambiguous on both Steam endpoints. Taurus is the bull.
ACH_NUSHI_CROWCorvus's End
the fight →
Crowconfirmed
Placed by the sync script with no judgement involved: this row's rank is currently unambiguous on both Steam endpoints. Corvus is the crow genus.
ACH_NUSHI_KUMAUrsa's End
the fight →
Bear — 熊 (kuma)corroborated
This row currently sits too close to a neighbour on unlock percentage for its rank to be certain across both Steam endpoints, so the mechanical join declines it and the pairing rests on the argument alone. Kuma is a bear, Ursa is the bear.
Outside corroboration · Both halves attested from outside. AllThings.How’s Ursa boss guide (Sehaj Padda, 4 August 2026) calls Ursa “the Nushi that caps Chapter 10 … a hulking bear”, at Lv. 46 — an independent source that played the game, naming the same boss and the same animal we derived from the id. It does not know about the internal id, which is what makes it independent.
ACH_NUSHI_WILD_BOARErymanth's End
the fight →
Wild boarinferred
This row currently sits too close to a neighbour on unlock percentage for its rank to be certain across both Steam endpoints, so the mechanical join declines it and the pairing rests on the argument alone. Erymanth is the Erymanthian Boar of the fourth labour of Heracles — the only boar in the naming scheme.
Outside corroboration · Half-corroborated, and the half matters. Fextralife published an Erymanth page on 6 August 2026 — a real boss, The Capital at Lv. 47, weak to Explosive, dropping “Kiku: Bloom Strike II” — so the name is no longer only ours. What that page does not say anywhere is that Erymanth is a boar. The name is attested; the animal tie to ACH_NUSHI_WILD_BOAR is still our inference.
ACH_NUSHI_KUno name could be attachedNot establishedunplaced
This row currently sits too close to a neighbour on unlock percentage for its rank to be certain across both Steam endpoints, so the mechanical join declines it and the pairing rests on the argument alone. A seventh Nushi id with no sixth-plus display name left to attach it to. It is not the dog: Koo’s own achievement is ACH_WITH_KUU, spelled with two Us. Published unplaced until a display name can be tied to it.

What this does not establish

Not the boss order. Unlock rates fall as you go down a critical path, so the ladder is consistent with the story order — but a low rate equally describes an optional boss most players skip. Nothing in the manifest separates the two, so no order is published here. Not a complete roster either: 7 ids against 6 names means at least one Nushi’s achievement is not named “…’s End”, and we cannot say which.

Method

How the two halves were joined

Neither Steam endpoint carries both the internal id and the display name. Putting them together is the useful part of this page and the only place it could quietly go wrong, so the rule is published with it.

Strategy: guarded-positional21 resolved25 unresolved

Both endpoints list the same achievements in unlock-rate order, so rows are paired by position. The two payloads disagreed by up to 0.3 points on the same row — they are cached at different times — so a row is paired only where it sits more than 0.6 points clear of both neighbours, far enough that the two could not have changed places between the snapshots. Every remaining achievement is published without an id.

Both endpoints list the achievements in unlock-rate order, so the sync pairs them by position and then asks, row by row, whether that position is trustworthy. It is not where two rows are tied, because neither endpoint promises the order inside a tie. And it is not where a row sits closer to a neighbour than the two endpoints disagree with each other — they are cached at different times, and two achievements that close could have changed places in between. An earlier version of this rule paired rows on equal percentages instead, which against drifted caches is a coincidence detector; it shipped wrong ids as confirmed and was replaced on 2026-09-06. Everything left over ships without one.

Beast of Reincarnation achievement FAQ

No. Unlock rates fall as you go down a critical path, so the ladder is consistent with the story order — but a low rate equally describes an optional boss most players skip. Nothing in the manifest distinguishes the two, and no order is published here.

Completion guides

The four achievements that name a countable set

Valve hides most of this game's achievement text from logged-out visitors, so most rows above carry no description at all. These four do, and the text names what to collect — which is the entire licence for giving them pages of their own.
