Sigil Resonance
The tactical expression of promises standing near one another.
Purpose
The Archive records what a Sigil means.
The Codex records what Sigils do together.
Resonance makes party composition visible, readable, and mechanically consequential.
Four Ways a Party Answers
A guide to the documented system design. Check the available action's preview for its current cost, targeting, and limits.
| System | Trigger and choice | Cost or limit | Result |
|---|---|---|---|
| Passive Resonance | Bring compatible sigils into the party. No battle command is required. | Requires the compatible party composition. | A passive benefit is established at battle start. |
| Oath Weave | An eligible Oath-Weaver selects an available sigil pair, checks its preview, and queues the action. | Uses the Weaver's action and the resources shown. Remaining Weave availability matters. | The chosen combination resolves its own targeting, damage, support, or status effect. |
| Compact Surge | A defined constellation of three or more sigils is present; activate its available Surge. | The design calls for a Weaver action, an MP cost, and one use per battle. | The constellation's named effect resolves. |
| Oath Rite | A Weaver uses Oath Burst; choose a Rite mode for the next successful Weave. | One active Rite. It is consumed by that Weave or expires at the end of the player phase under the V1 rules. | One Weave is transformed by the selected mode. |
Having compatible sigils does not itself spend a turn. Choosing a Weave does. A Rite modifies a Weave; it does not grant an extra action or replenish its resources.
Passive Resonance
Compatible Sigils activate when two or more linked units are present in the same party.
No command is required.
The party receives a passive benefit because the relationship already exists before the first action is chosen.
Weave Chains
When an Oath-Weaver is present, Resonance becomes an action.
The Weaver can bind two Sigils into a named Weave with its own targeting, effect, cost, and use limits.
Lyria is the universal catalyst. She can Weave any two Sigils currently present in the party.
Compact Surge
Some constellations require three or more Sigils.
When the correct pattern is present, a once-per-battle surge becomes available.
These effects are not generic bonuses. Each constellation has its own name and consequence.
Oath Rite
Oath Burst is personal expression.
Oath Weave is relational expression.
Oath Rite bridges the two: when a Weaver Bursts, a short Rite window can transform the next successful Weave.
Ruin, Ward, and Fate are the first Rite modes.
Ruin favors offensive damage. Ward adds protection. Fate favors the reliability of status effects.
Use the Window You Open
Design reference: Oath Rite V1, 23 April 2026.
Burst
A Weaver's Oath Burst opens a Rite window for the team. A non-Weaver's Burst does not open one.
Choose
Select Ruin for an offensive plan, Ward to prepare protection, or Fate when landing a status is the priority. Check that an eligible Weaver still has an action and the resources needed for the intended Weave.
Weave
The next successful Weave consumes the Rite and receives its transformation. A second Weave does not receive the same Rite.
Close
If no Weave succeeds before the player phase ends, the Rite expires. Another Weaver's Burst replaces and refreshes an existing Rite; it does not stack a second one.
For example, choose Ward before an available Weave when the party needs protection for the enemy phase. Confirm that the Weave can still be executed this phase before opening the window.
Return to one player phase to see preparation and execution in order.
A party is not six isolated units. It is a pattern waiting to answer.
