If you enjoy close-combat melee action and love punching enemies in **The First Descendant**, then Harris is a character you’ll definitely enjoy playing. Harris excels at jumping from one group of enemies to another while dealing heavy melee damage. At the same time, she provides valuable support by granting overshields to herself and other party members, helping keep everyone safe from potentially fatal hits. When you include Harris in your squad, you’re likely fielding one of the safest teams in the game.

To maximize her effectiveness, having a solid build is essential. In this guide, we’ll walk you through the best way to mod Harris, including the ideal Reactor, External Components, and Arche Tuning setups.

## Best Harris Build in The First Descendant

Harris is unique among Descendants because she **does not require MP to use her skills**. Instead, her first and second abilities operate on cooldowns—the shorter the cooldown, the more frequently you can use these powerful moves. Both abilities generate **Toxin**, a crucial resource needed to activate her third and fourth skills.

### Harris’s Abilities Overview

– **First Ability:** A barrage of heavy punches delivered with her unique mechanical arms called NOVA. The combo consists of three hits: the first two deal standard damage, while the third hit delivers double damage to finish off remaining enemies.

– **Crowd Control:** Each punch applies the *Towed* debuff, pulling enemies together and grouping them for easier targeting.

– **Toxin Generation:** Each hit generates Toxin, which fuels her other abilities.

With the right build, each hit from her first ability can reach **millions of damage**, making Harris especially effective across the Axion Plains and against the Void Intercept boss fights.

### Recommended Mod Setup for Harris’s 3-Hit Combo Build

– Safety Training (Transcendent module)
– Stim Accelerant
– Increased HP
– Nimble Fingers
– MP Conversion
– Skill Expansion
– Shield Charge
– Skill Extension
– Toxic Amplification
– Power Increase
– Pioneer’s Resolution (Ancestor module)
– Steel Vanguard (Trigger module)

Since Harris’s overshield scales with her HP, boosting your health pool significantly increases survivability. Her straightforward skill rotation focuses on constantly generating and spending Toxin. Use her first and second abilities to fill all three resource bars, then spend them immediately to maintain pressure.

Every time Harris’s Toxin level crosses certain thresholds—whether increasing or decreasing—she gains passive buffs. These buffs enhance cooldown recovery, duration, HP, defense, melee weapon attack, and skill power. Your objective is to keep these buffs active by continuously cycling your Toxin levels.

### Ancestor Module Details

The ideal Ancestor module for Harris is **Pioneer’s Resolution**, which allows stacking multiple stats and delivers a substantial damage boost to her abilities. If you don’t have one yet, **Skill Amplification** is a reasonable alternative.

When aiming to optimize your Pioneer’s Resolution mod, prioritize these stats:

– Skill Cooldown
– Fusion Skill Power
– HP
– MP

Keep in mind that re-rolling stats on Ancestor modules can be costly, so it’s okay to use whatever stats you currently have until you can further refine your gear.

## Best Reactor, External Components, and Arche Tuning for Harris

### Reactor

For Harris, the best Reactors are **Toxic Fusion** or **Toxin Tech**.

– Using a **Tech** Reactor maximizes the damage output of her punches.
– Choosing a **Fusion** Reactor boosts the damage of her laser beam ability.

For sub-stats, combining **Skill Cooldown** with either **Toxin** or **Fusion Power Boost** provides the most effective results.

### External Components

The **Plague set** is the top choice for Harris’s External Components. Although this set severely penalizes Firearm Critical Hit and Damage, equipping four Plague pieces boosts:

– Tech Power by 5%
– Toxic Skill Power by a massive 43%

Since Harris’s playstyle revolves around generating and using toxins, this substantial Toxic Skill Power boost greatly enhances her damage potential. Additionally, a custom resource generated for Harris (toxins) grants another 21% boost.

### Arche Tuning

Harris’s Arche Tuning board relies on two ultimate nodes, similar to the setup used in Hailey’s *Cold Heart* build.

– Prioritize the gold nodes **Enhanced Skill Power** for increased ability damage.
– To spam her first ability more frequently, invest in the **Enhanced Skill Cooldown** node.
– You may swap nodes based on your preference, such as exchanging **Enhanced Additional Skill ATK** or **Colossus** for **Skill Range** or more HP.

For the **Mutant Cell**, equip **Toxin Chain Catalyst** to reduce enemy resistance each time you hit them with a skill, further amplifying your damage output.

With these mods, components, and tuning choices, Harris becomes a powerhouse close-combat melee fighter with excellent survivability and team support. This build is well-suited for tackling all in-game content, ensuring you get the most out of her abilities in **The First Descendant**.
