Cards and Epiphanies

Duplicate Priorities
Unity of Attack and Defense > Rising Dragon Spire > Spirit of the Aromata

Mei Lin's best build focuses on fueling her Rising Dragon Spire to increase its hit count after using passion cards thanks to her multiple copies of Unity of Attack and Defense redrawing her 0-cost strike cards. Since her kit revolves around using passion cards, Passion Characters are a must have for her team so she can quickly increase the damage of her cards.

She is best suited with the 2/2/2 set consisting of Black Wing, Seth's Scarab and Executioner's Tool to enhance the damage of her strikes and her Rising Dragon Spire. Her favored chaos zone is Laboratory 0 to get her best equipment such as Mutant Predator Spike for more damage buff if there are 4 more cards in your hand. Wings of Freedom to get increasing 10% damage buff after getting hit for a total of 3 times and Emblem of an Exceptional Entity for additional damage amount added to all of her attack cards.

Mei Lin Best Team

Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Support	Sub-DPS
Rei	Veronica

Mei Lin's best team is Veronica and Rei. Veronica is also a Passion character that can draw a lot of cards and help Mei Lin find her essential cards to combo the enemy to death. The third spot for this team is Rei thanks to her ability to thin your deck with her exhausts and a handful amount of damage buffs that can significantly increase the effectiveness of Rising Dragon Spire and her strike basic cards.

List of All Characters

Alternative Team Members

Character	Explanation
Mika	Can replace Veronica or Rei as the Support if you ever need more survivability options and AP recovery if your built save data needs more AP.
Nia	Can replace Veronica or Rei as the Support to provide heals and targeted card draw for Mei Lin and can stand on her own for AP recovery if she has the Eternal Hunger forbidden card.
Selena	Can replace Rei as the Sub-DPS to synergize with Mei Lin's Passion Weakness mechanic. She has a lot of passion cards that can fuel Mei Lin's cards alongside more sub-DPS with marks.
Owen	Can replace Rei as the Sub-DPS to synergize with Mei Lin's passion card usage and even duplicate the use of Rising Dragon Spire if you have the right epiphany and enough AP to use.

Mei Lin Best Cards

Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Card	Epiphany Effect
Flame Dragon's Jewel	AP Cost: 1 Tags: Initiation, Unique ・+30% Attack Card Damage ・When using an Attack Card, 1 Passion Weakness to the target
Rising Dragon Spire	AP Cost: 2: ・150% Damage ・+1 hit for each Passion card used for 1 turn
Unity of Attack and Defense	AP Cost: 0 ・Move own 2 Basic Cards to hand, Cost -1 for 1 turn
Spirit of the Aromata	AP Cost: 1 Tags: Retain ・When using a Passion card, +20% Damage for 1 turn

The Flame Dragon’s Jewel increases your damage by 30% and grants you the ability to apply Passion Weakness on your next attack. This should be the first card you use, as its effects persist throughout the battle. You can also use the critical strike chance epiphany only if you have high enough critical strike chance on Mei Lin.

Focus on obtaining Unity of Attack and Defense to move your Strike cards from your draw pile to your hand at 0 cost. You should also aim to copy this card at the end of your Chaos Run, allowing you to resummon the Strike cards to your hand and greatly increase your damage potential in a single turn.

The Rising Dragon Spire, with its +1 hit for each Passion card used Epiphany effect, allows you to unleash a powerful attack after using all the Passion cards at your disposal in a single turn. Aim to activate this after playing all the Passion cards from both Veronica and Mei Lin to maximize your damage output.

Essential Team Cards and Epiphanies

Card	Epiphany Effect
Firing Preparation	AP Cost: 1 Tags: Unique, Initiation ・Create 1 Giant Ballista ・At the start of the turn, create 1 Giant Ballista card(s)
Repose	AP Cost: 0 ・Draw 2 other combatant's card(s)
Pendant of Resolution	AP Cost: 1 Tags: Retain, Retrieve 4 ・Reload 2
Sir Kowalski	AP Cost: 1 ・Choose 1 Ballista in Hand, +150 % Damage until used ・Draw 2
Strike of Darkness	AP Cost: 1 Tags: Unique ・+80% Basic attack card Damage
Resonating Darkness	AP Cost: 1 Tags: Unique ・+40% Damage of cards with cost 1 or below
Snack Time	AP Cost: 0 Tags: Exhaust 2 ・Select 1 card(s) from your hand to Exhaust ・Heal 150% ・Draw 1
Dark Condensation	AP Cost: 1 ・Select 1 Attack card(s), +100% Damage until used

Veronica needs as much draw power as possible so both Repose and Sir Kowalski should draw 2 and be as cheap as possible. While Pendant of Resolution needs the Retrieve 4 epiphany so that you can use it 5 times when Rising Dragon Spire is in your hand.

As for Rei's role in this team, all she needs to have are buffs to both Mei Lin's basic strike cards and then setup a turn to activate Dark Condensation and Predator's Blade before using Rising Dragon Spire to deal a ton of damage.

Details

Scarlet

Passive Effect:
Binding Knot - If a card used immediately before was from the assigned combatant, +15% attack card damage. Stacks up to 2 times and is removed if another combatant's card is used. When the assigned combatant uses 2 or more cards, they gain Focus. Focus: Attack card damage of the assigned combatant is increased by 20%. Remove Focus when another combatant's card is used.

Ego Skill:
The Path to Mastery - 250% Damage +10% assigned combatant's attack card damage per buff owned

Scarlet’s passive effect increases Attack Card damage by 15%, stacking up to two times when you use Mei Lin’s cards consecutively. You’ll also gain Focus, which further increases damage by an additional 20%.

List of All Partners

Alternative Budget Partners

Partner	Explanation
Lillian	Lillian’s passive effect synergizes well with Mei Lin’s basic Attack Cards, as it increases her damage by 10%. Her ego skill draws an Attack Card costing 0–1 AP, allowing you to add another attack during the same turn.
Douglas	Douglas can deal AoE damage using his ego skill which Mei Lin lacks but he can also provide a solid 16% attack stat increase if at max manifest ego allowing him to be the best substitute if you don't have Lillian or Scarlet.

Mei Lin Best Memory Fragments

Click on a Link to Jump to a Section!
Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

For Mei Lin, we recommend equipping Spark of Passion and Seth's Scarab. Spark of Passion grants additional Passion damage upon activating Flame Dragon's Jewel or Unity of Attack and Defense, while Seth's Scarab boosts the damage of her basic attacks—the core offensive cards for this build. For the main stats and substats, you can focus on Critical Chance, Critical Damage, Passion Damage, and Attack.

Replace Seth’s Scarab With Cursed Corpse if You Can Inflict Agony

If any of Mei Lin's teammates or herself can inflict constant Agony to the enemy then Cursed Corpse can replace Seth's Scarab to further boost not just her basic cards but also her Rising Dragon Spire.

Stat Priority

Main Stats	Recommended Substats
Ideal: Critical Chance % Desire: Passion Damage % Imagination: Attack %	・Critical Chance % ・Critical Damage % ・Attack % ・Attack

For both main stats and substats, aim for Passion Damage, Critical Chance, Critical Damage, and Extra Damage. Critical Chance is much preferred over Damage at the start, especially with the Executioner's Set immediately giving us Damage, and we'll want more crit chances to trigger critical strikes in the first place.

Mei Lin Best Equipment

Summary			Best Team			Best Cards			Best Partner
Memory Fragment				Equipment				Playstyle

Weapon	Armor	Accessory
Mutant Predator Spike	Wings of Freedom	Emblem of an Exceptional Entity

Mei Lin's best equipment can only be found in Laboratory 0 with Mutant Predator Spike increasing all her damage by 30% if you have at least 4 cards in hand. Wings of Freedom for 10% damage every hit taken up to 3 times. Emblem of an Exceptional Entity for an additional 30% damage increase unconditionally.

List of All Equipment

Chimeranite if She Can Draw Once per Turn

Weapon
Chimeranite

Chimeranite can boost all of Mei Lin's damage by 35% which is 5% more than Mutant Predator Spike if she can draw 1 card every turn. Do note that the move epiphany for Unity of Attack and Defense will not count as a draw if the basic card moves from discard pile to hand. However, if it moves from draw pile to hand then it is counted as a draw therefore activating the effects of Chimeranite.

Alternative Budget Equipment

Weapon	Armor	Accessory
Obsidian Sword	Incomplete Carapace	Amorphous Cube

If you aren't able to get the best, you can settle for these equipment that some can be found in any chaos zones inside shops. Obsidian Sword to boost the damage amount of her attack cards. Incomplete Carapace for shield if you have 5 or more cards in hand at the end of turn but can only be found in Laboratory 0 and Amorphous Cube gives a permanent +25% damage to all her attacks.

Single Target Multi-Hit Setup

Use the Move Version of Her Draw Card

Apply Passion Weakness to Break Enemies

Single Target Multi-Hit Setup

The Single Target Multi-Hit Setup makes use of Passion Cards from Mei Lin to stack hits for Rising Dragon Spire to increase the number of hits the attack does. The video above showcased Mei Lin hitting the target multiple times after playing all the passion cards you can in one single turn! The order of card use is:

Use Rei and Veronica's upgrade cards to boost the party damage and thin the deck
Use Spirit of the Aromata for the DMG Increase
Use every possible Passion cards you can from both Veronica and Mei Lin
Use Unity of Attack and Defense to Move 2 Strike Cards
Use All Strike Cards
(Optional) Use Dark Condensation and Predator's Blade to boost the damage of Rising Dragon Spire if you have the AP for it
Use Rising Dragon Spire to deal 150% with hits per Passion card used

Apply Passion Weakness to Break Enemies

Chaos Zero Nightmare Flame Dragon

You should always use the Flame Dragon's Jewel at the start of the turn to make Mei Lin apply Passion Weakness whenever she deals damage to an enemy. Since this is an Outbreak of War card, it will be placed at the top of the draw pile, allowing you to play the card at the start of the battle.

With the Passion Weakness applied, Mei Lin and Veronica's attack cards will deal high damage to the target's Tenacity.

Use the Move Version of Unity of Attack and Defense

Chaos Zero Nightmare - Move Unity Card

The draw keyword can only pull card from the draw and discard pile. However, move can pull cards from the draw, discard and used card pile making it so the strikes you used can be used instantly without needing it to go to the discard pile first.

Move Doesn't Count as Draw

However, the downside of move is that it is not considered as a draw therefore effects that gain benefits when drawn will not activate.

For mei lin on the crit set, you want seths scarab and black wing. The 4 set only works on 1 cost cards. So it misses your 0 cost strikes and 2 cost payoff card.

Anonymous about 1 month

the reason this of epiphany create 2 strike is because it "Upgrade" trait card, which is proc with Passion-4 set
