Hot Work Gear Set Guide for Arknights Endfield

Updated 6 November 2026 · Standard formula, shown below

This guide explains what the Hot Work gear set does in Arknights: Endfield, which operators benefit from it, and how to farm and upgrade it effectively. You will learn the set’s two-piece and four-piece bonuses, its ideal use cases, and how it compares to other gear sets.

What Is the Hot Work Gear Set?

The Hot Work set is a craftable gear set in Arknights: Endfield designed for operators who deal damage over time or rely on burning effects. It is part of the game’s gear system, where each set provides bonus effects when you equip two or four pieces of the same set. The set is commonly used on fire-aligned or DoT-focused operators to increase their sustained damage output.

According to the game’s current data, the two-piece bonus increases the wearer’s attack speed, while the four-piece bonus enhances damage against enemies suffering from burn or ignite status effects. This makes the set particularly effective in prolonged fights where status effects can be maintained.

How to Obtain Hot Work Gear

Hot Work gear pieces are obtained through the game’s crafting system and specific stages. Here are the main methods:

Crafting: Use the crafting bench to create gear pieces from materials dropped by enemies and gathered from the world. The required materials vary by piece and rarity.
Stage Drops: Certain story and resource stages drop Hot Work gear pieces as random rewards. Higher-difficulty stages have better drop rates.
Event Rewards: Limited-time events sometimes offer Hot Work gear as completion rewards or in event shops.

For efficient farming, focus on stages that specifically list the set as a drop. Check the stage details before entering to confirm the drop table.

Set Bonuses and Stats

The Hot Work set provides two distinct bonuses that activate based on how many pieces you equip:

Two-Piece Bonus: +8% attack speed. This increases the frequency of normal attacks, which is valuable for operators who rely on basic attacks to apply status effects.
Four-Piece Bonus: +25% damage against enemies affected by burn or ignite. This is a conditional damage boost that requires a consistent source of burn application.

Individual gear pieces also have primary and secondary stats that scale with rarity. For example, a five-star Hot Work headpiece might have ATK as its main stat, with sub-stats like Crit Rate or ATK%, while a four-star piece might have DEF. Always prioritize pieces that complement your operator’s role.

Which Operators Benefit Most

The Hot Work set is not universal; it shines on operators who can apply burn status or who deal damage over time. Ideal candidates include:

Fire-elemental operators whose skills naturally inflict ignite.
DoT specialists who rely on burn ticks for damage.
Attack-speed-dependent attackers who can stack the two-piece bonus with other speed modifiers.

For example, an operator with a skill that applies a burn effect on every third attack will benefit greatly from the attack speed bonus, as it accelerates the burn application. Conversely, operators with no burn synergy would be better served by a generic ATK% set.

How to Choose the Right Gear Pieces

When selecting Hot Work gear, consider the following factors:

Rarity: Higher rarity pieces have higher base stats and additional sub-stats. Aim for at least five-star pieces for endgame content.
Main Stat: Choose a main stat that matches the operator’s scaling. For damage dealers, ATK% or Crit Rate is usually best; for supports, ATK or DEF may be more appropriate.
Sub-stats: Prioritize sub-stats like ATK%, Crit Rate, Crit Damage, and Attack Speed. Avoid sub-stats like HP% or DEF% unless the operator specifically needs them.
Set Completion: Always aim for the four-piece bonus, as the two-piece bonus alone is rarely worth sacrificing other stats.

Use the in-game gear comparison tool to see how different pieces affect your operator’s overall stats before committing to upgrades.

Common Mistakes and Misconceptions

One common mistake is equipping the Hot Work set on operators without any burn application. The four-piece bonus is wasted if the enemy never receives burn status. Another mistake is ignoring the attack speed bonus; while it seems small, it can significantly increase the uptime of burn effects.

A frequent misconception is that the set works with any fire damage. In reality, only specific skills and effects apply the burn status; raw fire damage without a status effect does not trigger the bonus. Always read skill descriptions carefully to confirm that the operator applies burn.

Additionally, players often confuse the Hot Work set with the “Molten” set, which provides a different bonus. Molten focuses on raw fire damage, while Hot Work focuses on status effect synergy. Check the set name and bonus description before equipping.

Comparison with Other Gear Sets

To understand when Hot Work is optimal, compare it to other commonly used sets:

Molten Set: Provides a flat fire damage bonus. Better for operators who deal fire damage without relying on burn status.
Overload Set: Increases crit rate and crit damage. Better for burst damage dealers who can crit frequently.
Vanguard Set: Boosts attack and defense. A safe choice for balanced operators.

In practice, Hot Work outperforms Molten when fighting enemies that are weak to burn or in fights longer than 30 seconds, where the damage-over-time effect accumulates. For short burst fights, Overload or Molten may yield higher immediate damage.

Upgrade and Enhancement Costs

Upgrading Hot Work gear requires in-game currency and materials. The cost scales with the piece’s rarity and level. For example, upgrading a five-star piece from level 1 to level 20 might require several thousand gold and a handful of enhancement cores, while a six-star piece would need more.

To maximize efficiency, only upgrade pieces that have good sub-stats and are part of a complete set. It is better to wait for a better piece than to waste resources on a mediocre one.

Frequently Asked Questions

Does the Hot Work set work with any fire skill?
No. The four-piece bonus only triggers on enemies that have burn or ignite status. Skills that deal fire damage without applying a status effect will not benefit from the bonus.

Can I mix Hot Work pieces with another set?
Yes, but you will lose the four-piece bonus. Mixing two pieces of Hot Work with two pieces of another set can be viable if you need the attack speed bonus, but it is usually less effective than a full set.

Which rarity of Hot Work gear should I aim for?
For endgame content, aim for five-star or six-star pieces. Four-star pieces are fine for early game but will not provide enough stats for challenging content.

Is the Hot Work set good for support operators?
Generally no. The set is designed for damage dealers. Support operators usually benefit more from sets that boost healing or provide energy regeneration.

How do I know if an enemy is affected by burn?
Burn status is indicated by a flame icon above the enemy’s health bar. The duration and damage per tick depend on the skill that applied it.

Can I farm Hot Work gear from any stage?
No. Only specific stages list Hot Work gear as a drop. Check the stage’s drop table before farming to avoid wasting stamina.
