The gacha system in Arknights: Endfield features separate pools for Operators (characters) and weapons, each requiring distinct currencies. Operators are obtained through a dual-banner structure: a time-limited Chartered Banner with boosted rates for featured characters, and a permanent standard banner offering a fixed roster. Both banners can yield 4-star, 5-star, or 6-star Operators, but never weapons. A single pull costs 500 Oroberyls, a special currency earned from quests or by exchanging premium Origeometry (1 Origeometry converts to 75 Oroberyls). Alternatively, players may use Chartered HH Permits for seasonal banners or Basic HH Permits for the standard banner to perform pulls.
In the Chartered Banner, the featured unit has a 50.0000% probability of appearing when you successfully pull a six-star Operator. The overall drop rates for six-star, five-star, and four-star Operators across both banners are as follows:
1.Six-star operators: 0.8000%
2.Five-star operators: 8.0000%
3.Four-star operators: 91.20000%
The standard banner remains constant, while seasonal banners are time-limited and serve as the exclusive source for new six-star Operators. Following a seasonal banner's conclusion, its featured character will remain available as a potential drop within the next two seasonal banners. A key feature is that after making 30 pulls on a seasonal banner, players receive 10 complimentary "urgent headhunting" pulls to use on that same banner.To acquire signature weapons, you must perform an Arsenal Exchange. Access it through the Acquisition Center or via the button on the bottom-left of the Headhunt screen. Within this menu, you can pull for a featured character's signature weapon or purchase weapons from a weekly rotating shop using Arsenal Tickets. This unique currency is obtained from headhunting (pulling on character banners), the season pass, paid bundles, or by exchanging Origeometry.
A featured weapon has a 25.0000% drop rate, indicating a one in four chance of obtaining it when you successfully pull any six-star weapon. The standard probabilities for weapon rarities are listed below:
1.Six-star weapons: 4.0000%
2.Five-star weapons: 15.0000%
3.Four-star weapons: 81.0000%

In gacha games, pity system rewards players after a set number of pulls. Arknights: Endfield features two key thresholds for Operators. On both Chartered and standard banners, a five-star Operator is guaranteed every 10 pulls. After 80 pulls on a single banner, a six-star Operator is guaranteed. In the Chartered Banner, this six-star has a 50% chance to be the featured character. If it is not, you can pursue a 120-pity guarantee to obtain the rate-up character.
It is important to carefully manage these two pity counters, as they operate separately. Only the initial 80-pity counter carries over between seasonal banners; the secondary counter toward the 120-pity guarantee resets when a banner ends. Therefore, if you lose the 50/50 near a banner's end and continue pulling on the next banner, you may lose it again, since the 120-pity guarantee is only active on its original banner and can be triggered once per featured character.
Due to this system, it is advisable to secure enough currency for 120 pulls before committing to a banner, or you risk losing the 50/50 without reaching the guaranteed rate-up character. Additionally, during your pursuit of the first copy, reaching 60 pulls grants a Headhunting Dossier, which converts into 10 special permits for the next banner.
For duplicate characters, pulling a copy yields a Memento that unlocks one of the character's five passive abilities. A featured character's Memento is guaranteed after 240 pulls, regardless of when the first copy was obtained. The weapon gacha pity is simpler: only 10-pull batches are allowed. A six-star weapon is guaranteed every 40 pulls, but this pity does not carry over between banners. A rate-up six-star weapon is guaranteed after eight 10-pulls. Additional bonuses include an Arms OC: Smelting Forge crate every 100 weapons and a bonus rate-up six-star weapon at 180 weapons, each available once before the cycle repeats every 80 subsequent weapons.
