How to use this Memory
This 5★ Ruby Memory sits in the Solar slot and boosts HP. Solar slots (max 2 per team) anchor your key pairs and damage; Lunar slots (max 4) round out the team and let you match a battle's required Stellactrum. Equip it on Xavier, then line up its Ruby Stellactrum with your other equipped Memories — each matching point adds +5% (up to +100% at a full match), and meeting the battle's listed Stellactrum lets you break two Wanderer shields at once instead of one. Farm Ruby Protocores and slot them here to push its stats further.
Solar Pair
This Memory is one half of a Solar Pair. Equip both halves on Xavier for the Pair Bonus stat buff. No confirmed Myth story chapter is tied to this specific pair — treat it as a strong Pair Bonus combo.

Players report the Pair Bonus unlocks in stages as both halves rank up together: rank 0 unlocks the exclusive weapon, rank 1 unlocks a battle-damaged outfit, and rank 2 unlocks an alternate-color outfit. Treat this as a community-verified pattern, not an official patch note.
