Gacha Simulator
Simulates pulls on a Chartered (limited) headhunting banner in Arknights: Endfield. Everything runs in your browser — no account, nothing is sent anywhere.
⚠ Rates and guarantees in this tool follow the Endfield Talos Wiki (Headhunting page) and Game8. Of the rules simulated here, the only one that official notices state for Chartered banners is the rate-up 6★ within the first 120 pulls (pre-launch DEV Comm, 17 Jan 2026). The 0.8% base rate, soft pity after 65 pulls, the 6★ on pull 80 and the 50% rate-up chance are wiki figures; the official "6★ within 80 pulls" line applies to RE-Factor banners only. Check the in-game [Headhunting] rules before you spend.
- 6★ · 0.8% base
- 5★ · 8.0%
- 4★ · 91.2%
After 65 pulls without a 6★, each pull adds +5% (5.8% on pull 66, 10.8% on pull 67 …); pull 80 is a guaranteed 6★. Each 6★ has a 50% chance to be the rate-up operator, and once per banner pull 120 is the rate-up if you have not got it yet. If 9 pulls in a row give no 5★, the 10th is a 5★ or better (wiki). Per official notices, every 240 pulls on one banner also give a bonus token of the rate-up operator (not simulated). Off-banner 6★ results use the five standard 6★: Ember, Lifeng, Ardelia, Last Rite and Pogranichnik (Game8 lists them as the standard 6★ pool). The [Winter Hunt] notice also lists Liino and Arcane as possible non-rate-up 6★; this tool does not simulate them. Whether the 6★ count carries over to the next Chartered banner is disputed: the wiki says it does, a pre-launch Fextralife page says it does not, and official notices do not say.
Not modelled: on a Chartered banner, the official notice gives 10 free Urgent Recruitment pulls after 30 pulls, and a Headhunting Dossier (10 permits for the next Chartered banner) after 60 pulls. The 10 free pulls lower your real cost on this banner, so read the result as an upper bound; the Dossier only helps on the next Chartered banner.
