Myth Pairs
Pair up Memory cards that share a Stellactrum element to trigger resonance — see which combos to run.
Only 4★/5★ Solar Memory Cards carry a 2-letter pair code. Field both halves of the same code on one Companion to unlock a Pair Bonus (Duo Rank) that grows as the pair ranks up. The exact percentage at each rank hasn't been reliably cross-checked yet, so treat a completed pair as a strong team buff rather than a fixed number — and note that only the confirmed Myth pairs also unlock a story chapter.
