Lineup Mirror
Lineup Mirror (阵容镜像) is the Roco Kingdom: World system that lets players share and import team compositions from friends. Covers how mirrors are created, how they are imported, the totem and leader-transformation inheritance added in the April 9, 2026 patch, and best practices.
Overview
Lineup Mirror (阵容镜像) is a team-sharing system that lets a player capture a snapshot of their current spirit lineup, skill pages, and totem leader assignments, and ship it to a friend as an importable bundle. When a friend imports the mirror, the system automatically builds the matching team on their account using only the spirits and cosmetics they already own.
The system was expanded in the April 9, 2026 update. Imported mirrors now also inherit the ally team's totem leader transformation effects, and a pop-up warns the importer if the sender's mirror was missing a leader totem.
How it Works
Open the team management screen and select Lineup Mirror.
Capture a mirror of your current team. The mirror records the spirit list, skill configurations, stat allocations, item assignments, and any totem leader effect currently applied.
Send the mirror code or link to a friend through the in-game friend system.
The friend imports the mirror through the same menu. Spirits that the importer already owns slot in automatically. Missing spirits are listed with the biome where they can be captured.
Totem Leader Inheritance (April 9 Patch)
Before the April 9 patch, Lineup Mirror imports dropped the sender's totem leader transformation effect, which produced wrong lineups if the sender's team relied on a boss-form spirit. The patch corrected this:
Imported mirrors now inherit the sender's totem leader transformation directly. The importer does not need to re-apply the transformation.
If the sender's lineup did not include a totem leader, a pop-up now warns the importer during import so they can decide whether to attach their own leader before saving.
Boss-form spirits imported through the mirror follow the normal spirit kings leader transformation rules. If the importer does not own the required leader spirit, the slot remains empty.
When to Use Lineup Mirror
PvP scrims: Test a meta team with a friend before queueing Shining Contest ranked.
Team building guidance: Pull a lineup shared by a high-rank friend as a baseline, then swap out spirits you do not own using the team building guide to find substitutes.
Co-op content: Coordinate Territory Trial and Strange Beast Flora runs by sharing the runner and the support role templates.
