Core system
Bond
Bond belongs to the individual card code. Level it for stat points and more Attack slots.
Owned-copy progression
BUILD YOUR COPY.
Progression belongs to the copy, not the character. Use Bond to raise stats, awaken an Echo, learn Attacks and equip Artifacts.

Inside Bond
Echo
Use a Resonance Core from Bond to awaken a random, permanent Echo for that copy.

Inside Bond
Attacks
Attack Sigils let a copy learn special Attacks. It can know up to 10; equipped slots increase with Bond, up to 5.

Equipment
Artifacts
Equip Artifacts from the card's Bond menu. They add stats, and matching all 3 slots from one Set activates its Set effect.

Encounter structure
Teams
Encounters use saved four-card Teams. A Team is ready when all four codes belong to eligible cards you still own.
