In this game, the new character "Dawn" has become the easiest choice for beginners in the current version due to its unique summoning mechanism. Therefore, many players are curious about how to play Dawn in the Matrix Zero Day Crisis. In fact, she completely relies on the summoning creature "Shooter Cuby" for output. This build (BD) enhances Shooter Cuby through electric gameplay rules, increases attack frequency with bullet capacity/attack speed modifiers, and transforms output logic with potential keys, forming a "low dependency, high floor guarantee" build framework. The following will delve into the principles of the mechanism, construction path, and practical techniques from three aspects.

I. Core Mechanism: Permission Damage and Nullification Interval
Nature of the Damage Formula
Total Damage = Shooter Cuby Base Points × Percentage Increase
Base Points: Upgraded through the "Permission Upgrade" option (up to 10 levels), each level directly doubles Cuby's damage.
Percentage Increase: Comes from equipment modifiers (attack speed/bullet capacity), passive skills, and rule effects (such as electric gameplay evolution modifiers).
Invalid Damage Types: Includes weapon damage, skill damage, and critical hit bonuses which are ineffective against Cuby. Related modifiers (such as "Lucky Rule") need to be completely discarded.

II. Four Phases of BD Construction: Priority of Resource Allocation
Phase | Core Objective | Key Operations |
Start (Levels 1-2) | Lock Electric Gameplay Rules | Refresh initial rules until "Electric Gameplay Rules" (enhance shooting type Cuby) appears |
Middle (Levels 3-5) | Upgrade Permission Level to 10 | Select "Permission Upgrade" whenever encountered, prioritize maxing out base points |
Late (Levels 6-8) | Gather Attack Speed/Bullet Capacity Modifiers | Only keep "Attack Speed/Bullet Capacity/Reload Speed" modifiers on equipment |
Endgame (Boss Battle) | Trigger Qualitative Change by Refreshing Potential Keys | Reserve 1000 gold coins to refresh "Infinite Bullet Rain" (projectile count ×2) or "Perpetual Flow" (infinite ammo) |

III. Equipment and Rule Selection Strategy
1. Equipment Modifier Tiers
T0 (Mandatory): Attack Speed (directly boosts Cuby's attack speed), Bullet Capacity (extends output window), Reload Speed (reduces downtime).
T1 (Optional): Health Cap (increases survivability and fault tolerance), Global Damage (slight boost).

Discarded Modifiers: Critical Hit Rate, Weapon Damage, Skill Damage, Elemental Bonus.
2. Set and Quality Priority
Game Console Two-Piece Set: Provides 10% attack speed + 10% reload speed, early game transformative gear.

Backpack Type Equipment: Choose purple/gold backpacks with additional "Bullet Capacity + Attack Speed" modifiers (such as the "Tin Backpack").
Quality Upgrade: Must buy "Full Line Quality Upgrade" at the end-of-level shop (costs 3000 gold coins), golden Cuby's damage doubles.
3. Rule Benefit Grading
S Grade: Electric Gameplay Rule (evolution modifier "Shooter Cuby Damage +200%").
A Grade: Love and Rule (passive health cap), Music Rule (knockback when hit).
F Grade: Lucky Rule (critical hit related, completely useless).
IV. Practical Techniques: Operation Loop and Resource Management
Output Loop
Normal Phase: Maintain distance and auto-shoot, use cover to avoid projectiles.
Burst Window: Use C skill to fly (gain 10 seconds of increased damage) during boss battles, combined with the electric gameplay evolution modifier for instant kill.
Level Resource Decision
Purple Treasure Room: Can be skipped if difficulty is below 5, save time for upgrading permission levels.

End-of-Level Shop: Reserve 1000 gold coins to refresh keys, choose "Perpetual Flow" if "Infinite Bullet Rain" is not available.

Treasure Map: Only consider when lacking "quality upgrade" options (low cost-benefit ratio).
Potential Key Selection Logic
Key Type | Trigger Effect | Applicable Scenario |
Infinite Bullet Rain | Projectile count ×2 | Ultimate qualitative change, highest priority |
Perpetual Flow | 5% chance of no ammo consumption when shooting | Alternative choice when bullet capacity > 70 |
Weakness Insight | Increased damage to elites/bosses | Backup option if the first two are missing |
V. Matrix and Late-Game Development
1. Matrix Module Combination Suggestions:
Only effective modifiers: Attack Speed, Reload Speed, Bullet Capacity, Health Value, Shield Value.
Operation Tip: Right-click to rotate modules, prioritize combining survival modifiers (health/shield).
2. Weapon Unlock Nodes, note that the character unlocks a new 600 attack speed weapon at level 3 (replacing the initial 300 attack speed weapon), must be replaced before difficulty 5. Prioritize fully upgrading the "Ability Core" module page: Attack Speed after reloading (bottom left), Permission Damage (bottom right), Reload Speed (center).

The advantage of this BD lies in completely avoiding the numerical traps of traditional builds—through the single multiplier mechanism of "permission damage," it condenses output benefits into "base point level" and "attack speed/bullet capacity" linear paths, significantly reducing decision-making costs. In practice, the targeted enhancement of electric gameplay rules and the qualitative change effect of potential keys (such as Infinite Bullet Rain) together form the upper limit for burst damage to bosses, while the C skill flying mechanism further simplifies survival pressure. However, this build has a clear ceiling: lack of multiplier stacking potential (such as crits/elemental reactions) in the late game, and over-reliance on a fixed output mode. It is recommended that players switch to hybrid builds after clearing difficulty 8:
One is the sustained damage build: paired with the "Charm Layer Harvest" of the Love and Rule, achieving high-frequency DOT bursts.
The other is the weapon specialization build: using the heavy armor penetration characteristic of the new weapon "Overlord Destroyer" to transform into self-damage output.
Of course, in addition to the above playstyles, it's also important to pay attention to not missing output opportunities due to network lag during matches, and biubiu Accelerator is a good choice for speeding up. Now, it comes with a brand new upgraded version. This time, we specially invited champion player Aixleft to participate in the development, equipped with the super powerful Pallas Engine 3.0, so you won't have to worry about lag and disconnections when playing games or watching live streams anymore.

Now there are super value benefits, enter the code [biubiu no disconnection] to immediately unlock 3 days of VIP experience; new users using it for the first time enjoy exclusive benefits—24 hours of free time directly credited! Stacking both benefits, the total duration exceeds 96 hours, equivalent to 4 days of uninterrupted service.

In summary, the recommendation for building the Dawn BD in the Matrix Zero Day Crisis has been introduced. The "Shooter Cuby Build" with its extremely simple construction logic and low resource dependency has become the preferred solution for newcomers tackling high difficulties. Currently, the high floor advantage in the early game is its strength. If future versions open up Cuby synergy mods (such as crit conversion, area splash), it may release deeper playstyles. Overall, the current BD is positioned as the "optimal solution for early game," providing a solid foundation for exploring the core mechanisms of the game.
