Complete Guide to Elemental Reactions in Arknights Endfield

Understanding the Basics: How Inflictions Work

At its core, Endfield’s Elemental combat revolves around something called Inflictions—basically status effects that prime enemies for elemental reactions. Here’s the key thing to understand: an Infliction by itself does pretty much nothing. The magic happens when you layer them.

Every Operator skill can interact with Inflictions in three ways:

• Apply a new Infliction to an enemy
• Consume an existing Infliction to trigger a reaction
• Interact with Inflictions in unique, character-specific ways

When you hit an enemy that already has one Infliction with another skill, boom—you get a Reaction. The type of reaction depends on what elements you’re mixing and the nature of the skill itself.

Physical Damage and the Vulnerable System

Let’s start with Physical damage since it’s a bit simpler to wrap your head around. Physical skills always apply the Vulnerable Infliction when they connect. But here’s where it gets interesting—different Physical skill types consume Vulnerable in different ways.

Crush-Type Skills (like Endministrator’s Battle Skill):

• Apply Vulnerable on hit
• Consume Vulnerable stacks to deal bonus damage
• Great for burst damage when enemies are already softened up

Lift-Type Skills (like Chen’s Battle Skill):

• Apply Vulnerable on hit
• Don’t consume Vulnerable—instead add more stacks
• Launch enemies into the air for crowd control

The beauty of this system is you can chain these together strategically. Use Lift to stack Vulnerable while controlling the battlefield, then swap to Crush for a devastating finisher.

Other Physical reactions include:

• Breach: Consumes Vulnerable to make enemies take more Physical damage overall
• Knock Down: Slams Vulnerable enemies into the ground for control

Worth noting: some Operators like Ember blur the lines by dealing both Physical and Arts damage, giving you more flexibility in how you build your combos.

Arts Inflictions: The Four Elements

Now we’re getting to the fun stuff. Arts is Endfield’s term for elemental damage, and there are four types you’ll be working with:

• Heat (fire)
• Cryo (ice)
• Electric (lightning)
• Nature (poison/nature)

Just like Physical damage, Arts Inflictions don’t do much alone—they need to interact with other Inflictions to really shine. But Arts damage has two special mechanics that set it apart: Bursts and Reactions.

Arts Bursts: Stacking the Same Element

Here’s a cool trick: if you hit an enemy with the same Arts element twice, you trigger an Arts Burst. This creates a delayed explosion of that element for bonus damage.

For example, hit an enemy with Heat once to apply the Infliction, then hit them with Heat again—after a brief moment, they’ll take an additional chunk of Heat damage. The burst damage scales based on the hit that triggered it and your Operator’s Arts Intensity stat, so it’s worth investing in that stat if you’re running elemental-focused teams.

This is perfect for Operators who can rapid-fire the same element or when you’re coordinating with teammates in multiplayer co-op.

Arts Reactions: Mixing Elements

This is where combat gets really strategic. When you combine two different Arts Inflictions, you get an Arts Reaction. The crucial detail: the reaction type is determined by the element of the triggering skill, not the combination itself.

Here’s what that means: An enemy with Electric Infliction will Solidify when hit by Cryo. But if you reverse it—hit a Cryo-affected enemy with Electric—you get Electrification instead. Order matters!

The Four Arts Reactions

Combustion (Heat Trigger)

• Enemies burn and take damage over time
• Perfect for sustained pressure on tanky enemies
• Let it tick while you reposition or focus other targets

Electrification (Electric Trigger)

• Enemies become vulnerable to ALL Arts damage sources
• This is your damage amplifier—set this up before unleashing your heavy hitters
• Especially valuable in team compositions with multiple Arts damage dealers

Solidification (Cryo Trigger)

• Freezes weaker enemies completely
• Excellent crowd control for managing groups
• Can also be consumed by Crush skills for bonus damage (yes, Physical can interact with this one!)

Corrosion (Nature Trigger)

• Gradually reduces enemy elemental resistances
• The setup reaction for prolonged fights against resistant enemies
• Gets stronger the longer the fight goes on

Important: When you trigger an Arts Reaction, all Arts Inflictions are consumed. So you’re resetting back to a clean slate and can start building toward your next combo.

Character-Specific Combos and Advanced Interactions

Once you’ve got the basics down, you’ll discover that many Operators have unique twists on these systems. This is where choosing the right characters becomes crucial.

Take Wulfguard, for example. His Thermite Tracers skill normally applies Heat Infliction with the final shot. But here’s the kicker—if your target already has Combustion or Electrification active, Wulfguard consumes the reaction and fires an extra shot that hits way harder. That’s a completely different playstyle than just spamming Heat Bursts.

This kind of depth means there’s real value in reading your Operators’ skill descriptions carefully. Some characters are designed to be combo enablers, while others are finishers who capitalize on reactions you’ve already set up.

Practical Combat Tips

Start Simple: Focus on mastering one element combo before trying to juggle everything. Heat → Heat Burst is straightforward and effective.

Pay Attention to Skill Tags: Skills are labeled with their type (Crush, Lift, etc.) and element. This tells you exactly what they’ll do when they hit an enemy with existing Inflictions.

Think About Turn Order: In tough fights, plan out your sequence. Who applies the Infliction? Who triggers the reaction? Who capitalizes on the aftermath?

Invest in Arts Intensity: If you’re building an elemental team, this stat directly increases your Burst damage and can make reactions significantly more impactful.

Don’t Sleep on Physical Teams: While Arts reactions are flashy, a well-coordinated Physical team stacking and consuming Vulnerable can absolutely shred through content.
