RecruitmentOperatorsTag combinations

Recruitment is one of the two methods for players to get Operators in Arknights, aside from headhunting.

Overview

Recruitment is available after 0-2 is completed. Initially the player only have one recruitment slot (which means that one can only perform a single recruitment at a time), but building and upgrading the HR Office in the base increases the number of recruitment slots, up to 4.

Before carrying out the recruitment, the player should determine the recruitment time and tags to be used. Each recruitment costs LMD.png LMD and one Recruitment Permit.png Recruitment Permit; building and upgrading the HR Office reduces the recruitment fee by 10% at Level 1, 20% at Level 2, and 30% at Level 3.

Expedited Plan.png Expedited Plan can be used to instantly complete the recruitment. Though rarely, if ever, occurred, a recruitment can be completed in advance upon being carried out which will not use up the Recruitment Permit(s) and LMDs.

In the event the recruitment is cancelled (by clicking the Stop Recruitment button), the LMD and Recruitment Permit will not be refunded!

Recruitment time

The recruitment time can be set between 10 minutes and 9 hours, in 10 minutes increments. The longer the time, the lower the chance that the tag(s) are crossed out (see below), but the LMD cost is also increased.

Setting the recruitment time to at least 4 hours will remove 1★ Operators and add 5★ Operators, while setting it to at least 7 hours and 40 minutes will remove 2★ Operators.

Tags

There are five recruitment tags available on each recruitment slot, which decides what kind of the Operator will be recruited. All five are selected at random and not all of them are always available (see Tips), and the player can pick up to three tags at a time.

Once the recruitment is completed, the Operator will have the chosen tags unless if they are crossed out, which can happen in the following situations:

  • Randomly during the recruitment process, especially if the recruitment time is too short.
  • If the player selects two mutually exclusive tags (e.g. Medic and Guard), either or both of them will be crossed out.
  • Both of the above situations can still happen if the player uses Expedited Plans to instantly complete the recruitment, but not if the recruitment is completed in advance.

The possible tags are listed below, color-coded green for common ones, blue for semi-common ones, orange for uncommon ones, and red for rare ones:

Qualification Robot, Senior Operator, Starter, Top Operator
Position Melee, Ranged
Class Caster, Defender, Guard, Medic, Sniper, Specialist, Supporter, Vanguard
Specialization AoE, Crowd-Control, DPS, DP-Recovery, Debuff, Fast-Redeploy, Defense, Healing, Nuker, Shift, Slow, Summon, Support, Survival

The available tags can be refreshed once a HR Office is built on the base. One refresh chance is generated every six hours, up to 3 maximum, but certain Operators can accelerate it when they are assigned to work in the HR Office.

Tips

Mechanics

While the exact rate of recruitment tags are yet to be revealed from official sources, it is apparent that tag combinations' rarity are determined separately from the set of tags, which would mean that the tag generation process is done in two steps:

  1. The game determines the minimum rarity of Operators that would be guaranteed from the recruitment.
  2. The game randomly selects the tags and tag combinations that would guarantee Operator(s) of at least the minimum rarity.

As such, if during a tag generation process the game decides to pick 3★ as the rarity, then the generated tags and their combinations will often result in a 3★ Operator. This also gives the following implications:

  • Multiple uncommon and rare tags that guarantees at least 4★ Operators sometimes appear together (e.g. Support, Fast-Redeploy, and Shift at the same time) with or without common and semi-common tags that would guarantee specific Operators.
  • Combinations of common and semi-common tags that guarantees specific 5★ Operators (e.g. Defender/Defense and Survival which guarantees Vulcan, or Caster and Healing which guarantees Nightmare) seldom appears together.

Because of that, recruitment more heavily relies on luck than headhunting, but there is a bright side: while certain tag combinations' rates are adjusted when the recruitment pool is updated to accomodate the new additions, the tag generation process as explained above remains unchanged, which means that the overall rate in which Operators of a certain rarity appearing in recruitment stays the same.

Assuming the player didn't pick tag combinations which guarantees 4★ or higher Operators and sets the recruitment time to at least 7 hours and 40 minutes, the rarity of the Operator which appears from recruitment are as follows:[1]

  • 3★: ~87%
  • 4★: ~11%
  • 5★: ~2%

General

  • Try to choose a combination of tags that will guarantee at least a 4★ Operator or specific ones the player are looking. Remember to set the recruitment time to maximum (9 hours) to reduce the chance that any of the tags are crossed out.
    • If the player wants to get Robot Operators (Castle-3, Lancet-2, and THRM-EX), don't forget to set the time to at most 3 hours and 50 minutes, as any more than that will remove them from the search for being 1★ Operators.
    • If the set of tags did not guarantee specific Operators, the player can set the time to 7 hours and 40 minutes to save LMD, being the shortest possible to guarantee at least 3★ Operators and at most 5★ Operators.
  • If the player is very fortunate enough to get the Senior/Top Operator tag, always select either of them and set the recruitment time to maximum!
    • As long as the time is set to the maximum of 9 hours, the Top Operator tag will never be crossed out unless if a tag that counteracts it (e.g. Starter) is selected as well. Under the same condition, the Senior Operator tag will rarely, if ever be crossed out.
  • Early in the game, players should try to maximize their Operators' potential through recruitment, since as seen above, 3★ Operators are the most common sight in the recruitment process. Later in the game, recruitment is a great source for Commendation Certificate.png Commendation Certificate and Distinction Certificate.png Distinction Certificate, especially if the player were lucky enough to get 4★ Operators most of the time.
  • All current tags will be refreshed when new Operator(s) added to the recruitable Operators' pool. Therefore, the tags must be used as soon as the player gets them.
