Sealed Artifacts

Overview

Sealed Artifacts are extraordinary supernatural items in Lord of Mysteries that grant their user strange and powerful abilities, always at the cost of a significant drawback. In the fiction they are central to high-Sequence Beyonder operations and tightly controlled by the orthodox Churches.

In the live game they are also a full progression system. Artifacts unlock at character level 29, sit in typed slots, take socketed materials, and can be upgraded into higher quality tiers with a dedicated currency. This page covers both: the equipment system first, then the in-fiction classification that gives the artifacts their names.

Artifact names below are given in their Chinese forms with working English glosses. The game has no published English naming.

The Launch System

The system opens in stages across the published opening schedule:

Slot Categories

Artifact Classes

Beyonder Materials, Knowledge and Resonance

Beyonder materials (非凡物质) are the socketable layer. Only gold-tier materials that carry affixes are eligible, and they come in attack and defence types that must match the artifact they go into. From the third day of the schedule, players can aggregate materials themselves to chase better stats or a higher affix count before committing them.

Materials are a progression system in their own right, with a fusion layer, published star-up odds, and a rare mutated-affix tier. They are covered in full under Extraordinary Substances.

Two stats sit above the individual artifact. Beyonder Knowledge (非凡知识), raised through story progress and through proficiency rewards from material aggregation, lifts artifact skill attributes and Beyonder Resonance efficiency at the same time, across every equipped artifact rather than one at a time. Beyonder Resonance (非凡共鸣) is defined as the extra stat a multi-affix material yields once it is embedded, so Knowledge and Resonance compound.

Upgrading with the Echo of History

From character level 46, a sealed artifact can be levelled and pushed into a higher quality tier by consuming 【历史回响】, the Echo of History. It is mainly bought on the exchange with unbound soli. Published guidance is candid that for players who do not trade, the other acquisition routes are very limited and slow, and it deliberately holds back advice on which artifact to prioritise until the relevant progression points arrive.

The Echo of History is a currency. It is one character away from the Corridor of History (「历史回廊」), which is an artifact, and the two are routinely confused. They are covered separately below.

One-Click Assist

Sealed artifact one-click assist (封印物一键辅助) auto-casts an artifact's effect as soon as it comes available, but it is dependent rather than standalone: it only functions when base skill one-click assist is already enabled. In manual mode the toggle does nothing at all, even switched on. See Combat System.

Recommendations by Role

Published launch guidance maps day-one obtainable artifacts onto the game's role taxonomy:

The same guidance expects most players to have collected the whole set of currently previewable attack and defence artifacts by the second week after launch, so the matrix above is a priority order rather than a long-term scarcity problem.

Named Launch Artifacts

The Corridor of History

「历史回廊」, the Corridor of History, is a named sealed artifact rather than a currency, and the distinction matters because it differs from the Echo of History by a single character. The Corridor lets a player borrow power from the historical figures in their Connections roster, granting skills beyond the limits of their own Pathway and Sequence. Published examples name Old Neil attacking by spending debt, Susie healing by eating a Backlund pet biscuit, and Frank Lee summoning a mushroom that detonates for damage. Players can also unlock a transformation into a Connection's appearance. See Connections System for the roster and how it is built.

Classification Grades

In the fiction, the Churches classify Sealed Artifacts into four grades by danger, power, and sealing requirements:

A Sealed Artifact's power corresponds to the Sequence level and Pathway of the Beyonder Characteristic used to form it. An artifact formed from a Sequence 1 Beyonder's residue holds power approximating Sequence 1 Pathway abilities, with side effects to match. Every artifact carries a drawback, which may be physical (it drains the user), mental (it corrupts the user's sanity), conceptual (it warps reality around the user) or contractual (it demands a price for each use). The Churches catalogue drawbacks alongside abilities and rate the artifacts accordingly.

Notable Grade 0 Artifacts

Source-material references identify several named Grade 0 artifacts that surface in the campaign through cinematic moments or story-locked encounters:

These are referenced through Mr. Fool visions and Church archive scenes. Whether the player can wield any of them is gated behind story progression.

Church Control

Each orthodox Church maintains its own Sealed Artifact archive, with the Saint Selena Cathedral in Backlund hosting one of the largest collections. Older Churches, the Church of the Evernight Goddess and the Church of the Lord of Storms, tend to hold larger archives than newer ones; the Church of the God of Steam and Machinery, a relatively recent foundation, has a smaller collection.

The Machinery Hivemind, Nighthawks and Red Gloves can borrow artifacts from their Church's archive through a procedural request. Mid-tier operatives may receive Grade 3 or Grade 2 artifacts for a specific assignment, while Grade 1 and Grade 0 stay reserved for senior captains and special-mission scenarios.

Artifacts in the Story

Alongside the equipment system, artifacts reach the player through the narrative in several shapes:

Caveats

Sealed Artifacts are never handed over lightly. In the source material every one carries a drawback, and the live game models that directly: the named launch artifacts each pair a combat benefit with a cost, whether a curse, a health drain, a cooldown penalty or a stamina drain, and some uses will push Acting or sanity checks on activation. They are powerful but punishing tools.

Balance is a moving target. Values shown during the February 2026 Crimson Test and the Gray Fog Test were explicitly flagged as non-final at the time, and neither beta's numbers describe the live client. Expect the live game's iterative patches to keep moving them.
