What to know
-
Combat Records are Operator EXP materials used from the character menu’s level up flow.
-
Protocol Space: Operator EXP is the repeatable farming activity that directly rewards Combat Records, and it costs Sanity per run.
-
You’ll also pick up Combat Records naturally by progressing missions and opening chests while exploring Talos-II.
-
Advanced Combat Records have extra sources, including purchase via the AIC Quota Exchange (20 AIC Quota).
Arknights: Endfield asks you to level multiple Operators and weapons at once, so Combat Records become a constant bottleneck as soon as you start hitting level thresholds. If you want a steady, repeatable farm, you’ll lean on Protocol Space runs; if you want “free” extras, you’ll stack exploration chests and mission rewards as you clear content.
| Goal | Best method | Why it works | What it costs |
|---|---|---|---|
| Farm Combat Records on demand | Protocol Space: Operator EXP | Repeatable, direct Combat Record rewards | Sanity (stamina) per run |
| Get Combat Records while progressing | Story/side missions | Some missions reward Combat Records on completion | Time/progression |
| Stock up passively while exploring | Loot chests on Talos-II | Chests can contain Combat Records | Exploration time |
| Target Advanced Combat Records | AIC Quota Exchange | Guaranteed purchase option for Advanced | 20 AIC Quota each |
Combat Records explained (and why you run out)
Combat Records are leveling materials that provide Operator EXP, and you use them from the character menu when you hit the level up option. As you push Operators toward higher levels, your demand ramps quickly, so you’ll usually need a repeatable source rather than relying only on one-time rewards.
Types you’ll see:
-
Elementary Combat Record (Operator EXP material; used for leveling Operators up through the early-to-mid range).
-
Advanced Combat Record (higher-tier Operator EXP material).
How to farm Combat Records efficiently in Protocol Space
Protocol Space: Operator EXP is the consistent “grind loop” for Combat Records, because it’s designed to be replayed for predefined rewards. Each entry costs Sanity, so the main efficiency lever is choosing the highest Threat Level you can clear comfortably without wiping or slowing down.
Step 1: Unlock and locate Protocol Space: Operator EXP
Progress until Protocol Space becomes available, then select the Operator EXP variant so the reward table matches Combat Records.
Step 2: Pick a Threat Level you can clear consistently
Elementary Combat Records are rewarded from Protocol Space: Operator EXP at Threat Levels 1–4. Advanced Combat Records are rewarded from the same activity at Threat Levels 1–5, so higher tiers can include better EXP items once you’re ready.
Step 3: Spend Sanity, clear the run, and repeat
Entering the rift consumes Sanity, and you claim Combat Records as the completion rewards. Because it’s repeatable, this is your primary method whenever you’re hard-stuck on leveling due to EXP shortages.
Step 4: Plan Sanity around your leveling goals
If you’re pushing multiple Operators at once, run Operator EXP Protocol Space first so your EXP materials don’t block promotions and other progression checks. When Sanity is limited, prioritize the best Threat Level you can clear reliably rather than forcing harder tiers that slow your overall returns.
Where to pick up extra Combat Records while playing normally
If you don’t feel like hard-farming, you can still build a buffer through normal gameplay. Missions (story, side quests, and other mission types) can reward Elementary Combat Records on completion, so clearing your log naturally feeds your leveling stash.
You can also find Combat Records while exploring Talos-II by opening chests, which makes route-based exploration a nice “two birds” option when you also need map materials.
How to buy Advanced Combat Records (when you need a quick boost)
Advanced Combat Records can be purchased from the AIC Quota Exchange store for 20 AIC Quota each. This won’t replace farming long-term, but it’s a useful emergency lever when you’re just short of the EXP needed to push an Operator to the next breakpoint.
A practical farming routine
Run Protocol Space: Operator EXP whenever leveling blocks your progress, and use the highest Threat Level you can clear quickly and consistently. Between Sanity dumps, keep advancing missions and opening chests in Talos-II so you’re constantly topping up Combat Records without needing to “pure grind” every session.
If you want the most dependable Combat Record farm, Protocol Space: Operator EXP is the loop you’ll return to again and again, funded by Sanity. For smoother day-to-day progression, stack mission completions and chest routes in Talos-II, and use the AIC Quota Exchange as a last-mile boost for Advanced Combat Records when you’re nearly there.
