I'm assuming most of you understand the basics of recruitment by now, but the gist of it is that you pick a combination of tags and it gets you an operator that fits those tags. There is a chance of tags falling off, but you can increase the chance of them sticking by increasing the timer. The easiest way to guarantee a high rarity character is to make the "Senior Operator" or "Top Operator" tags stick, which will lock you into 5* and 6* characters respectively.

However there are a lot of tag combinations that lock you into a pool of characters that simply don't have any 4* or below characters. Assuming your tags stick, you'll get one of the 5* characters that are in that tag pool, even without that rare "Senior Operator" tag.

5* Only Tag Combinations:

Special thanks to the Arknights Toolbox site, super useful.

How To Use: Check the first column of this table for your tags. You don't need to check the second or third columns until you've got a tag matching the first column. Even if certain tags don't show up in the first column (ie. Survival, Vanguard, etc.) you need a matched pairing anyways so you'll catch the corresponding tag if it qualifies for a 5* combo.

Important: The "Supporter" and the "Support" tags are two different things, first one is a Class and the second one is an Affix. Same thing applies to "Defender"/"Defense". Please be careful not to mix these tags up.

4/28/22 Update - Aak (6*), Hung(5*), and Justice Knight (1*) added to the recruitment pool. No new 5* combos.

12/3/22 Update - Ceobe (6*), Bagpipe (6*), Sesa (5*), Leizi (5*), Utage (4*), and Purestream (4*) added to the recruitment pool. Sesa shares Meteorite's tags, no new 5* combos otherwise. Purestream breaks the Support Healer/Medic combos, so those are now removed (RIP Ptilopsis and Warfarin combos).

1/13/23 Update - Phantom (6*), Shamare (5*), and Cutter (4*) added. Cutter breaks the previously 5* exclusive Nuker tag. Shamare shares tags with Pramanix.

PM me if I missed any of the new combinations/updates, or if the new 3* and 4* pool broke any of the old 5* guaranteed combos. I don't keep up as closely anymore, so I'll be relying on you all to ping me if the list needs updating. Best of luck to you all in your recruitments!
