Arknights: Endfield gacha and pity explained
In Arknights: Endfield, the gacha and pity systems run the show, just like in any other pull-based RPG. Headhunting is where you roll for Operators, while weapons live in a separate pool. If you’re planning out resources, knowing exactly how the pity counters behave will save you from burning pulls at the wrong time.
Endfield’s setup is familiar, but there are a few quirks worth noting before you commit your Origeometry or tickets. Here’s how gacha and pity work across Operator and weapon banners.
How the gacha works in Arknights: Endfield
Headhunting covers two things: Operators (characters) and, via a different menu, weapons. Each uses its own currency.
For Operators, there are two banner types: a limited Chartered Banner and a permanent standard banner. The Chartered Banner features a specific unit with increased odds when you hit a six-star; the standard banner pulls from a fixed roster. Operator banners do not include weapons.
A single Operator pull on either banner costs 500 Oroberyls. You can earn Oroberyls in-game or convert Origeometry at a rate of 1 Origeometry = 75 Oroberyls. Special tickets also work: Chartered HH Permits for limited banners and Basic HH Permits for the standard banner.
When you roll a six-star on the Chartered Banner, the featured unit has a 50.0000% chance to be the result. Base drop rates on both Operator banners are:
- Six-star operators: 0.8000%
- Five-star operators: 8.0000%
- Four-star operators: 91.20000%
The standard banner stays put, but seasonal Chartered Banners rotate and are the only place to find brand-new six-stars. After a seasonal banner ends, its rate-up unit can still appear as a possible six-star in the next two seasonal banners.
There’s also a small bonus: after 30 pulls on a seasonal banner, you’ll receive a free “urgent headhunting” 10-pull for that same banner.
Weapons live in the Arsenal Exchange. You can open it from the Acquisition Center or the button on the lower-left of the Headhunt screen. Here, you either pull for the featured character’s signature weapon or buy from a weekly rotating shop, both using Arsenal Tickets. You’ll earn these tickets from headhunting (Operator pulls), the season pass, paid bundles, or by converting Origeometry.
When you pull a six-star weapon, the featured option has a 25.0000% chance to be the one you get. Base weapon drop rates are:
- Six-star weapons: 4.0000%
- Five-star weapons: 15.0000%
- Four-star weapons: 81.0000%
How the pity system works in Arknights: Endfield
Operator pity is straightforward but has two thresholds you need to track. On both Chartered and standard banners, you’re guaranteed a five-star every 10 pulls. At 80 pulls on a single banner, a six-star is guaranteed. On a Chartered Banner, that guaranteed six-star has a 50% shot to be the featured unit; if you lose the 50/50, you can aim for the 120th pull, which guarantees the rate-up six-star.
Be careful with carryover. Only the 80-pull counter carries from one Chartered Banner to the next; the 120-pull guarantee does not. If a limited banner ends after you lost the 50/50 and you roll 40 more pulls on the next banner, you can lose that 50/50 again because the 120-pull safety reset with the previous banner. The 120-pull “hard pity” only works while that specific seasonal banner is active, and it triggers once.
Given that, it’s best to queue resources so you can reach 120 pulls on the seasonal banner you actually want. Otherwise, you risk missing the featured unit twice back-to-back.
There are a couple of extras tied to progression. While chasing your first copy of the featured Operator, hitting 60 pulls grants a Headhunting Dossier that converts into 10 special permits usable only on the next banner.
If you’re hunting dupes, each duplicate grants a Memento for that Operator, unlocking one of five passive abilities. For featured Operators, a Memento is guaranteed after 240 pulls. That threshold doesn’t change whether your first copy arrives at 80 or 120 pulls—you’ll still be guaranteed a dupe at 240. You might get it earlier, but odds are slim.
Weapon pity is simpler. Arsenal pulls are only available as 10-at-a-time. If you go three 10-pulls without a six-star weapon, the next 10-pull is guaranteed to include one. That counter does not carry between Arsenal banners. For the featured six-star, a guaranteed rate-up drops after eight 10-pulls (each 10-pull costs 1,980 Arsenal Tickets). You can hit it earlier, but any six-star along the way might be off-rate.
There are milestone bonuses, too. Every 10 pulls (100 weapons total) grants an Arms OC: Smelting Forge crate that lets you pick one of the six basic five-star weapons. At 18 pulls (180 weapons), you also receive a bonus rate-up six-star weapon. Those two bonuses trigger once; after that, every eight 10-pulls awards either another Smelting Forge crate or a duplicate of the featured six-star weapon.
