How to use this Memory
This 4★ Ruby Memory sits in the Lunar 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 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.
