Sephiria Artifacts Guide — Tablets and Inventory

Sephiria Artifacts activate as soon as they are acquired, while Tablets strengthen adjacent Artifacts in the backpack. The verified research describes about 300 Artifacts and about 70 Tablets, making placement and adjacency central parts of a run. Individual item names and exact effects are not included in the supplied material, so this page explains only the confirmed system.

What Artifacts Do

Artifacts are one of the major systems that shape a Sephiria build. Their effects become active immediately after acquisition, so they are not described as equipment that must first be placed into a separate activation slot. The research does not state that every Artifact works in exactly the same way, only that acquisition activates them as a category.

The game contains approximately 300 Artifacts according to the verified source summary. That number communicates breadth, but it should not be treated as a complete item database or a promise that every patch exposes the same count. Names, rarities, numerical values, drop sources, and individual effect text are not present in the source and therefore remain 待确认.

How Tablets Change the Backpack

Tablets strengthen adjacent Artifacts. This confirmed rule means physical position in the backpack can change the value produced by an otherwise identical collection. The backpack is therefore a strategic layout system, not merely a list of objects collected during the run.

The source records approximately 70 Tablets. It does not define Tablet shapes, orientation rules, stacking behavior, maximum adjacency, or whether one Tablet can strengthen several Artifacts at once. Those details would require direct, current evidence and are 待确认 rather than assumptions based on other inventory games.

The Confirmed Scale of the System

About 300 Artifacts and about 70 Tablets sit alongside six weapon branches and more than 200 weapon upgrades. Sephiria also includes 30+ potions, 20+ costumes, six chapters, and 18 hard-mode elements in the supplied facts. Together these numbers establish that the game has a broad progression and build space.

Scale alone does not identify the strongest item. A large pool can produce many possible interactions, but the research does not provide drop weighting, tiers, or a version-specific ranking. Any exact tier list would need additional evidence gathered from the current game version and is outside the verified material used here.

Artifacts Inside a Complete Build

Weapons, weapon upgrades, Talents, Miracles, characters, and backpack placement all influence a run. Artifacts are therefore one layer of a larger build rather than the only source of power. The confirmed relationship is systemic: these choices collectively determine how a run develops.

The source does not name a mandatory Artifact for a weapon branch, Talent, Miracle, or character. It also does not give a formula for measuring one combination against another. A responsible build page can describe the confirmed layers, but any named recipe or precise damage comparison remains 待确认 until supported by real data.

Reading Adjacency Honestly

The safe factual interpretation of adjacency is that a Tablet strengthens Artifacts next to it. Players can use this rule to understand why rearranging a backpack matters, but the source does not state which side or distance qualifies as adjacent. It also does not explain whether multiple Tablets combine additively, multiplicatively, or under a cap.

That missing detail matters when evaluating screenshots or community recommendations. Two layouts may look similar while producing different results if shape, direction, or stacking rules apply. Until those rules are verified, this guide avoids turning a broad adjacency statement into an invented optimization formula.

Artifacts in Online Co-op

Sephiria supports online co-op for up to four players, and item trading is confirmed. This allows a group to move items between teammates, although the supplied material does not identify which categories can always be traded. A player’s current backpack layout can logically be considered when discussing an Artifact, but exact trading restrictions remain 待确认.

Teammates can also revive one another. The research does not claim that any Artifact modifies revival, team size, trading, or shared rewards, so no such effect is presented here. The factual connection between Artifacts and co-op is limited to the confirmed existence of item trading within a build-heavy game.

What Is Still Unverified

The material does not contain an Artifact list, item names, exact descriptions, rarity levels, unlock rules, vendor prices, drop locations, or tier rankings. It does not identify Bond Artifacts beyond earlier planning language, so any precise Bond rule is also 待确认. These omissions are deliberate boundaries, not hidden recommendations.

For changes after the source verification date, consult the official Steam announcements and the official Steam page. Sephiria entered Early Access on April 3, 2025, released version 1.0 on July 31, 2026, and the supplied research was last checked on August 10, 2026. Later patches may change counts or rules, so current official information should take priority.
