How to Use the Arknights Recruitment Calculator (Tags & Guaranteed Operator Filter)

Public Recruitment in Arknights is a free, passive method to acquire 4-star, 5-star, and 6-star operators without spending precious Orundum or Originite Prime. However, missing a rare tag combination like 'Crowd-Control' or 'Debuff + Fast-Redeploy' can mean throwing away guaranteed 5-star operators and gold certificates.

Our Arknights Recruitment Calculator evaluates your available tag pool, identifies every guaranteed 4★, 5★, and 6★ combination, and reveals potential operator outcomes so you never accidentally drop a valuable tag.

Formula & Calculation Methodology

\text{Pool} = \bigcap_{i} \text{TagOperators}(T_i), \quad P(\text{Tag Drop}) \approx 0 \text{ at } t = 9\text{h}
  • Top Operator: The ONLY tag that unlocks 6-star operators in standard recruitment
  • Senior Operator: Guarantees a 5-star operator when not dropped
  • Specialist / Shift / Fast-Redeploy: Guarantees 4-star minimum (Shaw, Rope, Gravel) for green certificate farming

Grounded in the current Arknights global recruitment operator pool and official tag classification rules.

Frequently Asked Questions

Why should I always recruit for 9 hours in Arknights?
Setting your recruitment timer to 9 hours completely removes 1-star and 2-star operators from the pool (unless selecting the 'Starter' or 'Robot' tag) and significantly reduces the probability of a chosen tag being randomly crossed out (dropped).
Can you get a 6-star operator without the 'Top Operator' tag?
No. It is mathematically impossible to recruit a 6-star operator without selecting the 'Top Operator' tag. Even with Senior Operator or 9 hours set, 6-stars never appear unless Top Operator is explicitly chosen.
What should I do if I get 'Top Operator' and 'Senior Operator' together?
Always select 'Top Operator' and NEVER select Senior Operator alongside it. Combining both can cause one of the tags to conflict or be dropped. Pair Top Operator with a class tag (like Guard or Defender) to target a specific 6-star.
How do recruitment tags help farm Green and Yellow Certificates?
Every 4-star operator recruited yields 30 Commendation Certificates (Green Certs) and 1 Distinction Certificate (Yellow Cert) on duplicate tokens. 5-stars yield 5–8 Yellow Certs. Farming Gravel via 'Fast-Redeploy' is the fastest way to buy out monthly headhunting tickets in the certificate shop.
How do I target 1-star robots like Castle-3 or THRM-EX?
Set your recruitment timer to 3 hours and 50 minutes (or under 4 hours) and select the 'Starter' or 'Robot' tag with Melee or Guard. Setting 9 hours will lock robots out.
