Chronicle of the White Knights Dream Kingdom

Memory Turbulence Effect
After every attack launched by an ally, apply 1 stack of Memory Imprint to all enemies. Enemies with Memory Imprint receive 5% more DMG. This effect stacks up to 6 stack(s). When Memory Imprint stacks to maximum stacks, immediately deal DMG based on a certain percentage of each enemy's respective Max HP 1 time to all enemies. When enemy targets enter battle and other units in the field currently have Memory Imprints, the new enemies will receive the same number of Memory Imprint stacks as those on the field. At the start of every wave of each Cycle, remove Memory Imprint from all enemies.
Phase Duration	04/15/2024 - 05/27/2024

Eve of Wanton Feast

Memory Turbulence Effect
Summons a Trotter at the beginning of each wave or each Cycle. The Trotter takes 200% more DMG from Basic ATKs and DoT effects. When the Trotter is defeated, if an enemy is afflicted with Bleed, Shock, Burn, or Wind Shear, immediately deals DMG equal to 50% of the original DoT effect to them, with a high chance to inflict Bleed, Shock, Burn, and Wind Shear on all enemies for 3 turn(s).
Phase Duration	03/18/2024 - 04/29/2024

Memory of Chaos Stage 12 Best Teams

Chronicle of the White Nights Dream Kingdom Best Teams

Bring Lightning and Quantum in the First Half

All enemies in the first half are weak to Lightning DMG. You can also use an Imaginary DPS and Silver Wolf since half of the bosses in the first half are also weak to that element.

Use Ice and AoE Units in the Second Half

In the second half, all enemies are weak to Ice. You can also bring a Physical unit as The Ascended and Aventurine are weak to that element.

We recommend bringing characters who can deal AoE DMG to win Gambles in Wave 2 of the second half.

Eve of Wanton Feast Best Teams

Bring Imaginary and Wind Units in the First Half

All enemies in the first half are weak to Imaginary and Wind. We also recommend bringing a character who can remove enemy buffs to deal with the Shape Shifter and the Mara-Struck Soldiers.

Bring an Abundance Unit in the Second Half

In the second half, we recommend bringing an Abundance unit since you will be up against Sam, an enemy who can deplete your HP through Skill Point consumption.

Aside from Lightning, you can also use Ice and Imaginary as most enemies are weak to those elements.

How to Beat Stage 12 - Chronicle of the White Nights Dream Kingdom

Chronicle of the White Nights Dream Kingdom First Half

Take Out the Everwinter Shadewalker Summons

In Wave 1, take out the Everwinter Shadewalkers as soon as they're summoned to prevent them from slowing down your units.

Save the Shell of Faded Rage for Last

For both waves, prioritize the Frigid Prowler and Cocolia before the Shell of Faded Rage as they're tougher enemies to take down.

For Cocolia in particular, once she charges up to unleash her Punishment of Endless Winter attack, focus on Weakness Break to cancel it.

Chronicle of the White Nights Dream Kingdom Second Half

Take Out the Team Leader First

In Wave 1, focus on taking out the Team Leader and his summons to collect Performance Points. This will help you easily take down The Ascended.

Use AoE Attacks on All or Nothing Dice

In Wave 2, use AoE attacks on the All or Nothing Dice to have more chances of winning Gambles. Winning a Gamble will prevent your character from taking DMG and restore their energy for their Ultimates.

How to Beat Stage 12 - Eve of Wanton Feast

Eve of Wanton Feast First Half

Defeat the Shape Shifter First in Wave 1

Between the two elite enemies, focus on taking out Shape Shifter first in Wave 1. This is so you can avoid prolonging the fight as the Shape Shifter is capable of healing himself.

Take Out the Trotter First in Wave 2

In Wave 2, Yanqing will summon his Flying Swords at the start of his turn and his Type Weakness will be disabled.

Take Out the Sequence Trotter first to apply DoTs to the Flying Swords and make it easier to enable Yanqing's Weakness.

Eve of Wanton Feast Second Half

Defeat The Ascended First in Wave 1

Between the two elite enemies, focus on taking out The Ascended first in Wave 1. This is so you can get rid of the Prana-Siphon debuff before taking on Sam in the next wave.

Damage the Automaton Direwolf First in Wave 2

Focus on attacking the Automaton Direwolf first in Wave 2 since Sam's weakness is disabled until he unleashes Secondary Combustion.

Once Sam's weakness is enabled, focus on using your Skill Points to attack Sam. This will deplete his Molten Energy and eventually weaken his defenses.
