How to use this Memory
This 5★ Sapphire Memory sits in the Solar slot and boosts DEF. 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 Zayne, then line up its Sapphire 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 Sapphire Protocores and slot them here to push its stats further.
Myth Pair
This Memory is one half of a Myth Pair. Equip both halves on Zayne to unlock the exclusive Myth memory chapter and its Pair Bonus stat buff.
