Mei Lin Build and Team Guide in Chaos Zero Nightmare

To build Mei Lin effectively following balance nerfs to her base damage coefficients, run her as a dedicated burst carry supported by external Action Point (AP) generation, defense shredding, and aggressive deck pruning. Her kit relies on chaining low-cost setup strikes into heavy finishers, making critical hit scaling and hand consistency mandatory to offset her lowered base multipliers.

Deck Construction and Card Upgrades

Mei Lin suffers severely from resource starvation and dead hands. To keep her damage rotations consistent, remove low-impact basic attacks at early card deletion nodes and focus your drafting on cards that sustain card flow and reward combo chains.

Card Priority	Category	Strategic Focus
Essential	Burst Finishers	Heavy scaling per attack played that turn, Critical Damage conversion, and execute mechanics.
High	Combo Starters	1-AP cost or crit-based AP refunds, multi-hit generation, and draw triggers.
Medium	Utility & Cycling	Turn-to-turn card retention, hand filtering, and enemy vulnerability debuffs.
Remove ASAP	Basic Strikes	Unmodified starter attacks that dilute your deck and stall burst turns.

Upgrade Priorities

Finishers first: Upgrade your multi-hit and execute finishers at rest sites and enhancement stations. Because their damage scales directly with the number of attacks played in a single turn, upgrading them provides the highest damage floor increase.
Cost-reducing starters second: Enhance combo starters that refund AP or draw additional cards on critical strikes to maintain momentum during high-tempo turns.
Prune early: Delete unmodified basic strikes as soon as deck management services appear. Drawing filler cards instead of combo starters prevents Mei Lin from reaching lethal damage thresholds.

Stat Priorities and Gear Optimization

Because Mei Lin's baseline multipliers are reduced, gear her purely for offensive amplification. Do not divert primary gear stats into defensive attributes like flat HP or physical defense; rely on teammate shields and buffs for survivability.

Critical Strike Rate: Secure a high, consistent Critical Strike Rate before investing in raw damage. Mei Lin requires critical hits to trigger core passive effects, card refunds, and equipment procs.
Critical Damage: Once your critical consistency is established, prioritize Critical Damage to maximize the multiplicative value of her multi-hit bursts.
Flat and Percentage Attack: Stack flat Attack on early equipment slots and percentage Attack increases on higher-tier gear to build the base values for her multi-hit scaling.
Action Point / Speed Utility: Seek gear substats or set bonuses that grant bonus starting AP or speed up her turn order, allowing her to unload bursts before enemies establish protective barriers.

Team Composition and Synergies

Mei Lin cannot generate sufficient AP or self-buffs to carry encounters alone. Run her as a solo carry alongside dedicated supports rather than in a split-damage setup where attackers compete for the same AP pool.

AP Batteries: Pair Mei Lin with units capable of supplying extra AP or refunding skill costs. Mei Lin requires at least 4 usable AP during her burst turns to execute complete starter-into-finisher sequences.
Defense and Vulnerability Shredders: Teammates who inflict physical or elemental vulnerability multiply her output significantly, preventing high-armor elite targets from neutralizing her multi-hit attacks.
Attack and Crit Buffers: External Attack Up and teamwide Critical Damage buffs replace the base scaling lost in balance updates.

A standard composition should feature Mei Lin as the primary carry, one dedicated buffer or debuffer, and one support providing AP generation and defensive sustain.

Combat Rotation

Executing Mei Lin’s rotation requires disciplined resource management rather than spending AP on low-impact chip damage every turn.

Setup and Filter: Spend early turns using utility skills to filter your hand, thin the deck, and apply vulnerability debuffs to elite targets. Bank AP whenever possible while assembling your combo pieces.
Buff Initiation: At the start of the burst turn, cast all teamwide damage buffs and enemy defense reduction skills before playing Mei Lin's attacks.
Combo Chain: Play low-cost, multi-hit starter cards to accumulate attack stacks, trigger equipment procs, and activate AP refunds.
Finisher Execution: Conclude the turn by casting your fully upgraded finisher to apply the maximum accumulated attack-count multipliers and execute bonuses.
