Caleb: Nether Yearning

This 5★ Emerald 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 Caleb, then line up its Emerald 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 Emerald Protocores and slot them here to push its stats further.

This Memory is one half of a Solar Pair. Equip both halves on Caleb 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.
