Past memories lie buried deep within dreams, and the key to exploration is in your hands. Please do not forget, only within dreams will the answers be revealed.

[Eligibility]
Reach Union Level 30.

[Exploration]
- Choose three Resonators and embark on epic battles in the Illusive Realm.
- The Echo Skills, Stats, Levels, Resonance Chains, and Weapons of Resonators can be carried over in the event.
- In the Illusive Realm, you can gain powerful boosts from Metaphors. Metaphors marked with Dreamscape Power provide additional enhancements when Divined Dream is activated through Dreamscape Aid.
- Each battle in the Illusive Realm brings you against different enemies. Complete these challenges to earn Illusive Points and reach milestones to claim bountiful rewards.

[Remnant Crystal]
A Remnant Crystal will appear in the Memory Zone after defeating the powerful enemies found in the deepest parts of the realm. Use Waveplates to collect its rewards.

[Difficulty]
Higher SOL3 Phases offer more challenging Exploration in the Illusive Realm with more rewards from the Remnant Crystals and Illusive Points. The difficulty of the Illusive Realm is dependent on the SOL3 Phase you're in when the Illusive Realm resets (04:00 every Monday). Adjusting your SOL3 Phase during each exploration cycle does not affect the difficulty and rewards of the current cycle.
