Review
Mei Lin is a 5-Star Striker that belongs to the Passion attribute. Mei Lin excels at dealing single-target damage to knock her enemies out.
Mei Lin is capable of constantly applying Passion Weakness to enemies, ensuring she almost always has an Attribute advantage to maximize her damage output. Mei Lin can also inflict "Ember" on her enemies, which provides extra damage to Attack Cards when they're used on enemies that will be put into a Ravaged state or are currently in one.
Mei Lin has phenomenal AP efficiency and consistency thanks to her "Unity of Attack and Defense" card. She has great self buffs and can dish out some incredible damage without much help from other Combatants. Mei Lin is primed to be your key DPS in a team and benefits best from other Combatants who can provide buffs to supplement their damage output.
Her glaring weakness is her lack of AoE damage; none of her cards or various Epiphanies have the ability to provide in this area. In content where AoE is needed, she may fall short. Whilst Mei Lin has Card Draw on her own, it's limited to her own cards, so she will still want to be paired with another unit who can assist with Card Draw to ensure she can activate as many of her cards as possible in a single turn.
Mei Lin plays almost like a fighting character, chaining together long strings of Attack Cards to form potent ramping combos to continue her assault.
Self Card Draw/searching and AP cost reductions.
Incredible self-buffing capabilities.
Can apply Passion Weakness on enemies to always deal Tenacity Damage and gain attribute damage bonus herself and Passion Allies.
Outstanding burst single-target damage.
Ego Skill is expensive
No AoE Cards.
The ratings below are based on the Season Save Data, Chaos Manifestation, and Great Rift modes. Each of the modes values different mechanics, so some characters may shine in one of them, while being underwhelming in the other.
Passion Weakness: A debuff that causes the enemy to be treated as though they are Passion weak for all Combatant attacks while it remains active. It is duration-based, not hit-count-based.
Attack Weakness/Weak Point Damage: Makes an Attack Card deal damage as if it had an elemental advantage.
Ember: Applies a stacking debuff to the enemy. When the enemy is Ravaged, or hit while in a Ravaged state, deal +30% damage per Ember stack and consume all stacks (up to 5 stacks).
Combo: Gain additional effect after activating another card of the same elemental type.
Ravage/Ravaged: Enemies in this status have had their Tenacity Bar fully broken.
Tenacity Damage: Depletes enemies' Tenacity Bar. 1 Tenacity Damage is 1 Bar of the gauge.
Mei Lin’s 3-1 is one you’ll want to pick up quickly, while her other signature Potentials add damage stats to her kit based on her Attack stat. If you’re hitting those stat thresholds, they are also definitely worth grabbing.
3-1: Causes Strike to add 1 Ember stack to the enemy on use. Makes it easier to generate stacks of Ember for more bonus damage when breaking or hitting broken enemies.
5-1: Adds an extra 5% base damage to Strike. Additionally, if Mei Lin’s Attack is greater than 500, an additional 5% is added, for 10% total.
7: Adds 4% Weak Point Damage if Mei Lin’s Attack is greater than 600. For every 50 Attack over 600, +1% Weak Point Damage is added, up to 8% extra. Mei Lin is almost always dealing Weak Point Damage, so the extra damage here adds up fast.

Heavenly Flame Dragon
Ego Skill
Mei Lin’s Ego Skill is expensive, costing 6 EP to use, but doubles the hit count of her next 4 Basic Attacks, offering a tremendous amount of burst potential when combined with Unity of Attack and Defense. These additional basics have no time limit on them, so you can use this Ego as soon as it's available and reap the benefits whenever it’s convenient.

Strike
Attack
Mei Lin’s Basic Attacks are a core part of her kit, which are discounted, empowered and used extensively by the rest of her kit. You’ll be using them very… very often. Also applies 1 stack of Ember per use after unlocking Potentials!

Flame Dragon Guardian
Skill
Show Effects
Basic Shield card that can be drawn and used for 0 cost via Unity of Attack and Defense, but is otherwise unremarkable.

Flame Dragon's Jewel
Upgrade
Show Effects
Mei Lin’s signature card is one of the strongest upgrades available. It costs 1AP to use and grants all of Mei Lin’s Attack Cards a multiplicative +20% boost while also causing them all to apply 1-turn of Passion Weakness, essentially ensuring she’ll always have elemental advantage and the damage bonus that comes with it. Even better is that this card has [Initiation], meaning you’ll always be able to use it at the start of fights! It also has the [Unique] tag, meaning it cannot be stacked.

Rising Dragon Spire
Attack
Show Effects
A 1-Cost Attack Card that deals damage, applies 2 Ember stacks and has a Combo effect that causes it to hit twice. An incredibly efficient damaging card with very loose restrictions, given the high AP efficiency of the rest of Mei Lin’s cards. If you’re worried, though, you can pair Mei Lin with another Passion character to guarantee it’s always active.

Unity of Attack and Defense
Skill
Mei Lin’s best card, which, when upgraded and copied, can form truly degenerate combos when built around correctly, but is still incredibly strong at a baseline as well. It is a 0AP cost skill that draws 2 Basic Cards (Strike or Flame Dragon Guardian) and reduces their cost by 1 for the current turn. It's straight up a 0-cost draw 2 gain 2 AP, which is incredible
Note: If there are not enough eligible cards for this card to draw, it will draw them from the Grave as well. ALSO, if a card has already been played this turn, it CANNOT be drawn again; this can be BYPASSED with an Epiphany that changes DRAW to MOVE.

Spirit of the Aromata
Skill
Show Effects
Another buffing card for Mei Lin, but this time a temporary one. Cost 1 AP and grants Mei Lin a unique effect that causes her to gain an additional +20% DMG multiplier every time she plays a card, stacking infinitely. This effect and its buff last 1 turn. This is absurdly potent when combined with Mei Lin’s many low or no-cost cards. Also has [Retain], allowing it to be saved for the perfect moment.

Flame Dragon's Sovereignty
Attack
Show Effects
This card has [Attack Weakness], meaning it will always deal damage as if it has an elemental advantage. It hits for 300% damage before whatever buffs you might have/give it. On top of everything else, if you break an enemy with it, it deals all the extra Ember damage you have stacked onto the target without consuming the stacks.

Gear
The Memory Fragments & Equipment suggestions below are based on calculations we did. If you want to check the damage formula and how scaling the damage works in CZN, check this guide.
The safest of all set combination for Mei Lin to use in Chaos and Save data based game modes but which can lose out to more specialised sets under the right circumstances. Check out Mei Lin's other gear options to know which scenarios they beat out 2/2/2 for.
Loses out to all other sets in Save Data based game modes but can work as an alternative to 2/2/2 in Chaos based game modes although it's not specifically a direct upgrade and more of a side grade thanks to how competitive 2P Seth's Scarab is alongside the other 2 DPS 2P sets.
In save data based game modes Rising Dragon Spire V is the majority of Mei Lin's damage and baseline it has an AP cost of 2. So long as you're not reducing its cost via discounts or Divine Epiphanies 4P Line of Justice is a large damage upgrade thanks to the Crit Rate it grants to Dragon Spire making it a strong choice but only if your Mei Lin build aligns with it.
Similar to Line of Justice 4P Conqueor's can be used to boost Rising Dragon Spire V as well but only when it's discounted which is most common via a Divine Cost Reduction Epiphany. When you can guarentee your Dragon Spire V costs exactly 1 AP consistenly this is a damage upgrade over 2/2/2 .
In a lot of cases, flat sub-stats are better than percentage ones when it comes to HP, ATK and DEF. The reason behind this is that in CZN the characters stats are pretty low and you get more value from flat bonus rather than percentage one based on calcs.
CRIT Rate% = CRIT DMG% > ATK > ATK%
To activate Mei Lin's potential 7, ensure she has at least 601 ATK in the character screen, but ideally aim for much more than this to get as close to maxing out its effect as possible. The Weak Point Damage from Potential 7 is one of the strongest multipliers available to Mei Lin, so getting more of it is ideal.
Our best Partner recommendation try to balance both the raw damage boost they provide based on our calculations with the additional utility provided by the skill - combined with how it interacts with the character's kit. We have rated each Partner based on how much additional damage and the utility they provide. Read the comments under each Partner to better understand our reasoning.
No calculations in Chaos Zero Nightmare are completely accurate for all scenarios, including the ones below. What team, decks, epiphanies, gear, equipment, and enemies you're facing all impact them. Because of this, take the results as guidelines and combine them with the explanations to make your decisions. Calculations use endgame save data set-ups, including 5 turns of combat using the whole deck with all Ego skills unless otherwise stated.
In the Zero System, it's incredibly easy to access all items acquirable via the shop thanks to the five free refreshes you get each shop node - that's why the recommendations below are limited to them only. ATTENTION! Area-specific items can sometimes be more powerful than shop items, but are far less consistent to get or require running a specific world or giving up certain event options. Use the shop list as a starting point for building up your deck saves.
The equipment recommendations are based on items obtainable in Season 2’s Chaos - Burning Life. If you’re running content outside of Season 2, it’s possible some options may not be available for acquisition, or that other options not obtainable in Burning Life may be better.
We're currently working on updating all builds for Season 3.
