Sephiria Achievements Guide

Why track Sephiria achievements

Sephiria on Steam (app 2436940) ships 27 achievements for the 1.0 release. Most unlock while you climb six chapters, learn secret rooms, and finish the story. A smaller set needs intentional detours: alternate bosses, hub conversations, animal rescues, and Root’s Retreat Hard Mode stages.

This guide organizes the full list using official Steam titles and community-verified unlock conditions. Percentages shift over time — treat Steam’s global stats as a rarity hint, not a walkthrough. Pair this page with Chapter Walkthrough, Hard Mode, and Bosses when a specific fight blocks progress.

Sephiria has no redeem codes. Achievement hunting is runs, Sapphires, and pattern literacy — not promotional strings.

Sephiria 1.0 full release overview — context for achievement hunting

Campaign and boss milestones

These unlocks arrive by playing the main tower loop and defeating chapter gatekeepers. Exact floor labels in community guides sometimes say “Floor 1–6”; this wiki maps them to the six-chapter climb used elsewhere on the site.

Achievement	How it unlocks
DIY	Repair your house (Ken’s Home Repair / town rebuild loop from Talents).
Stronghold Exploration	Defeat the Mole Chief (Chapter 1 / Mole Base opener).
Sky of the Roofless Tower	Defeat the Pillager Leader (Chapter 2 Grassland finale family).
Traveler	Find a hidden / secret room.
This Is Not Stalking	Defeat the Mad Scientist (Library / Chapter 3 chain).
Where the Blue Being Lives	Enter a rare blue portal tile when it appears in a dungeon.
Enlightened Scholar	Defeat Askard (Chapter 4 wasteland leader).
Chapter I through Chapter V	Story progression milestones after key chapter beats and World Tree Seed conversations.
Broken System	Defeat the Guardian of the Library.
At the End of the Cave	Defeat a Guardian Demon of Qliphoth (Chapter 5 chain).
Gatekeeper of the Mind	Defeat the second Guardian Demon of Qliphoth.
Three but One	Defeat the Mind-Eater Root.
Hero’s Guise	Defeat Qliphoth.
Temple of Evil	Late-game temple / animal escort completion (bring rescued animals to the Temple of Qliphoth).
Seal	Finish the ritual that seals Qliphoth’s core.
Journey’s End	Watch ending credits after completing the game.

After a full clear, Patch 1.0.21 added title-screen Credits access — useful if Steam did not pop Journey’s End on the first ending view. Patch 1.0.23 also attempts to restore a missing final achievement when you re-enter town.

Alternate bosses and missable combat unlocks

After early chapters progress, Sephiria can replace some chapter finales with harder variants. Hunt these if Steam still shows them locked after a story clear:

Achievement	Target
Endless Bombs	Defeat the Demolition Expert (harder Mole Chief replacement).
Hunting Duel	Defeat the Shadow Blade (harder Pillager Leader / assassin replacement).
Qliphoth Contractor	Defeat Mutated Askard (stronger Askard variant).

These are pattern exams on top of the base fights. Prep with Chapter 1 Bosses, Chapter 2 Bosses, and Askard, then push until the alternate spawn appears. Do not reset inscription just because an alternate did not show on one run — RNG and story flags both matter.

Hub, exploration, and conversation unlocks

Achievement	Practical tip
Traveler	Bash cracked walls near room tops; see Secret Rooms.
Where the Blue Being Lives	Blue portals are rare — enter immediately when spotted.
Soul Plan	Complete the special conversation with Perr at the World Tree base.
Chapter V / Temple of Evil	Find and save three hidden animals in late areas, then escort them to the temple.

Animal rescue and temple steps are the main late-story missables. Keep exploring side rooms instead of speedrunning every chapter door.

Root’s Retreat Hard Mode achievements

Three achievements track Hard Mode stage clears inside Root’s Retreat:

Achievement	Requirement
Root’s Retreat	Clear Hard Mode Stage 1.
Root’s Retreat 15	Clear Hard Mode Stage 15.
Root’s Retreat 30	Clear Hard Mode Stage 30.

Unlock Hard Mode after campaign progress (community guides cite a free World Tree / roots node after Chapter II). Full modifier prep lives on Hard Mode; stage milestones and rewards live on Root’s Retreat. Practice telegraphs in Gauntlet Mode and Training Grounds before stacking high stages.

Efficient 100% route

1. Finish Ken’s house (DIY) early via Talents.
2. Clear chapters with Chapter Walkthrough pacing; open every cracked wall for Traveler.
3. Enter any blue portal for Where the Blue Being Lives.
4. Farm alternate bosses after story flags allow replacements.
5. Complete Perr / animal / temple steps before assuming the ending closed every missable.
6. Graduate to Root’s Retreat stages 1 → 15 → 30 with a coherent Recommended Builds grid.

Co-op and patch notes for hunters

Achievements are account-bound through Steam. Co-op through the Mysterious Door can help with tough bosses, but no host migration still applies — see Co-op. After major hotfixes through Patch 1.0.24, re-check town if a final unlock failed to register.
