The Hot Work gear set is a late-game equipment collection in Arknights: Endfield designed for operators who leverage heat and nature damage. It consists of six pieces that work together to amplify elemental damage output, making it valuable for endgame content where these damage types matter.
Quick answer: The Hot Work set grants a 3-piece bonus of +30 Arts Intensity, plus conditional damage boosts: +50% Heat damage for 10 seconds after applying Combustion, or +50% Nature damage for 10 seconds after applying Corrosion. These effects cannot stack simultaneously.

What the Hot Work Set Includes
The complete set contains six pieces, all at Gold rarity and level 70. The Hot Work Exoskeleton is the armor piece, providing 87 Strength and 58 Agility, plus 11.5% Heat and Nature damage bonus. Two glove variants exist: the standard Hot Work Gauntlets (43 Strength, 65 Intellect, 19.2% bonus) and Hot Work Gauntlets T1 (43 Intellect, 65 Will, 19.2% bonus), allowing flexibility in stat distribution.
The kit pieces round out the set. Hot Work Power Bank delivers 32 Strength, 21 Agility, and 41 Arts Intensity. Hot Work Pyrometer adds 41 Intellect and 41.4% Battle Skill damage bonus. Hot Work Power Cartridge provides 21 Intellect, 32 Will, and 41 Arts Intensity. Together, these pieces emphasize Arts Intensity while distributing stat boosts across multiple attributes.

How the Set Bonus Works
Equipping three pieces of the Hot Work set triggers the core bonus: your operator gains +30 Arts Intensity immediately. This stat amplifies the effectiveness of arts-based abilities and damage calculations.
The conditional effects activate based on what status you apply to enemies. When you apply Combustion to a target, Heat damage dealt by the wearer increases by 50% for the next 10 seconds. Alternatively, applying Corrosion triggers a 50% boost to Nature damage for 10 seconds instead. The two effects cannot stack—only one can be active at a time, so you choose your approach based on the enemy and your operator's kit.
Best Operators for Hot Work
Laevatain and Wulfgard are the primary users of this set. Both operators benefit from the Arts Intensity boost and can reliably apply Combustion or Corrosion to trigger the damage multiplier. Laevatain especially excels with the set in late-game scenarios where heat damage becomes a core damage source. Wulfgard similarly leverages the conditional bonuses as part of both early and endgame setups.

How to Obtain Hot Work Recipes
The Hot Work gear recipes drop from Gear Template Crates found in the Wuling region. These crates may contain pieces from multiple sets, so you may need to open several to collect the full Hot Work set.
