Rafayel: Wisteria Waltz

This 5★ Sapphire Memory sits in the Lunar slot and boosts ATK. 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 Rafayel, 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.
