Memory - 01: "[Labyrinth] Challenge - 01"

Enemies

Altar Gemstone: Light (20,500 HP)
Apprentice Researcher Rei (32,015 HP)

Team Recommendations

At least 3 low cooldown (3-4 turns) units
Non-AoE units or bring the new Quincy if you use these

Stage Tips

When the Light Gemstone is in a state of "Essence Depletion", please pay attention to Rei's hints and perform at least 3 Strong Attacks on <Altar Gemstone ‧ Light> to make the gemstone enter a state of "Essence Abundance", otherwise the gemstone will trigger "Essence Backlash", dealing massive damage to all.
When <Altar Gemstone ‧ Light> is in a state of "Essence Abundance", it will temporarily not absorb any essence. Attacking the gemstone at this time will cause its essence to drain, increasing the challenge duration.
When <Altar Gemstone ‧ Light> is in a "Stabilizing State", please have positions 1~5 perform Basic Attack, Guard, Basic Attack, Guard, Ultimate Skill in sequence to see the stage through to completion.

Focus on the gemstone and don't hurt Rei or let him die.
The gemstone won't be damaged much on the first 4 turns, so prepare your ultimates in that time.

End of turn 3/8/11: The gemstone will heal itself slightly.
On turn 5/9/13: Use at least 3 ultimates this turn.
On turn 6/10/14: Guard all or heal, just don't attack the gemstones.

When the gemstone reaches 10% HP, follow this order to finish the battle:
- Slot 1: Basic attack
- Slot 2: Guard
- Slot 3: Basic attack
- Slot 4: Guard
- Slot 5: Ultimate

Memory - 02: "[Labyrinth] Challenge - 02"

Enemies

Listless Purple-Haired Gambler Kuya (359,139 HP)
Coat Rack (36,328 HP)
Irritable Golden-Haired Drinker Quincy (358,002 HP)

Team Recommendations

Non-AoE units unless you use new Quincy
Elements are irrelevant here

Stage Tips

When Kuya uses "Burn", Quincy will "Resist" the burn damage. During the turn-by-turn damage period of "Burn", have at least 2 allies guard to withstand the raging flames.
When Kuya "Mocks" Quincy, Quincy will begin charging power. Do not attack Quincy at this time, or it will add fuel to the fire, causing Quincy's "Assault" to deal higher damage.
When Kuya decides to get "Earnest" and Quincy is also "Prepare for Battle", have all allies guard to withstand the impact caused by subsequent attacks.

There are multiple thresholds in the fight that happen once both Quincy and Kuya are a certain HP threshold.
- At 90% HP for both, Quincy and Kuya hit one another down to 60% HP.
- At 50% HP: Quincy and Kuya will attack one another again down to 10% HP.
- At 1% HP: They'll finally leave!

At the start of the fight: The coat rack will be killed and your party will be taken down to low health.

End of turn 1/8/15: Kuya will apply a bleed that would normally kill you, but Quincy gives you an out here.
On turn 2/9/16: Guard at least 2 units this turn.
On turn 3/10/17: Guard at least 2 units again.
On turn 4/11/18: Do not attack Quincy this turn or he will gain +30% damage per attack!
On turn 5/12/19: Do not attack Quincy this turn either.
End of turn 5/12/19: Quincy will attack the party.
On turn 7/14/21: Guard all to avoid the strong incoming damage.
End of turn 7/14/21: Both Kuya and Quincy will use strong attacks on the party.

Memory - 03: "[Labyrinth] Challenge - 03"

Enemies

Altar Maintainer Huey (404,996 HP)

Team Recommendations

Elements don't matter here
At least 3 units that damage with their ultimates
Anything that lowers damage taken or strong healers

Stage Tips {{When Huey begins to "Stop Guidance", it's recommended for all allies to perform Strong Attacks, break through the Essence Vortex, and reach the required essence output amount. If not achieved, you will suffer "Rebound", increasing the challenge difficulty. Pay Attention! You need at least 3 Ultimate Skills to deal damage to Huey and assist allies in healing. Recommended to have <Healer> attack second-to-last, stabilize allies' HP, then have the main damage dealer perform Ultimate Skill. When Huey gives a "Command", you need to perform Basic Attacks to reduce Huey's damage to resist the gemstone's "Chaos" Strong Attack. Afterward, Huey will "Prepare to Harmonize" essence. At this time, you cannot deal substantial damage to Huey. Please have all allies guard, and after Huey's healing, resist the impact of "Essence Resonance".}}

Huey causes you to permanently take 5% more damage every 2 turns, so this will stack quickly!

On turn 5/9/13: Use ultimates to remove the shield on Huey, using your strongest ultimate last due to applied buffs. Be careful since each attack will damage you!
On turn 6/10/14: Use 5 basic attacks here. Do not guard or you will die! Watch your health though since Huey will counterattack the party.
End of turn 6/10/14: Huey will attack the party with an ultimate.
On turn 7/11/15: Guard all.
End of turn 7/11/15: Huey will use a strong ultimate.
