Most Endministrators budget for 80 pulls and call it a guarantee. That number is real, but it guarantees the wrong thing. Arknights: Endfield runs two separate pity systems stacked on top of each other, and understanding which one actually gets you the Operator you want, not just any 6-star, is the difference between a funded pull plan and a banner that runs out of Origeometry halfway through.
The 80-pull pity guarantees any 6-star Operator. The 120-pull guarantee is the one that actually locks in the specific, featured character you're pulling for. Budgeting for 80 and hoping the coin flip goes your way is how funded accounts end up short.
The two pity systems in Arknights: Endfield, and why they get confused
Character pulls on Chartered Headhunting (the Limited banner) run on a base rate of 0.8% for 6-star Operators, 8.0% for 5-stars, and 91.2% for 4-stars, with a 5-star or higher guaranteed on every 10-pull. Sitting on top of that base rate are two independent counters.
The first is general pity: reach 80 pulls without a 6-star and one is guaranteed, and that counter carries over between banners of the same type, resetting to zero only when any 6-star actually drops. The second is the featured guarantee: reach 120 pulls on a single Limited banner and the specific rate-up Operator is guaranteed, no coin flip involved, but that counter is tied to that one banner and gets wiped when the banner ends.
These two systems interact through a 50/50. Any 6-star that drops before pull 120 triggers a coin flip between the featured Operator and an off-banner standard character. Win it, and the featured Operator is yours early. Lose it, and the only way to guarantee the specific Operator is to keep pulling up to the 120-pull mark, where the featured guarantee overrides the coin flip entirely.
Does 6-star pity carry over between banners in Arknights: Endfield?
Only the 80-pull general pity does, and only within banners of the same type. If your last 6-star landed at pull 74 on one Chartered banner, the next Chartered banner you pull on starts already 74 pulls into its own 80-pull counter, not back at zero. The 120-pull featured guarantee behaves completely differently: it never carries over, it applies only to the single banner it was earned on, and it disappears the moment that banner rotates out. Treating both counters as if they reset together, or as if they both carry over, is the single most common and most expensive mistake Endministrators make when planning a pull budget.
The 80-pull soft pity formula in Arknights: Endfield
The 0.8% base rate for a 6-star does not stay flat all the way to pull 80. From pull 66 onward, the system enters what amounts to a growing pity phase: every pull past 65 adds roughly 5 percentage points to that pull's 6-star chance, following the shape p = 0.008 + 0.05 × (n − 65).
By pull 80, that climbing rate reaches 100%, which is where the hard guarantee sits. Because the curve climbs so steeply once it starts, the statistical average landing spot for a 6-star sits in the low 70s rather than at the 80-pull ceiling most players plan around. Budgeting strictly for pull 80 usually overshoots what a typical pull sequence actually needs, but it is still the number to hold in reserve, since soft pity is a probability curve, not a promise.
How many pulls does it actually cost to guarantee a 6-star in Arknights: Endfield?
In Oroberyl terms, each single pull costs 500, exchanged from Origeometry, and a 10-pull costs 5,000. Guaranteeing any 6-star costs at most 80 pulls, or 40,000 Oroberyl in the worst case, though the soft pity curve means most players land one closer to pull 72 on average.
Guaranteeing the specific featured Operator, the number that actually matters for a targeted pull, costs up to 120 pulls, or 60,000 Oroberyl, in the scenario where the 50/50 is lost at hard pity and the remaining 40 pulls are needed to force the featured guarantee. That 120-pull, 60,000-Oroberyl figure is the real budget ceiling for a single featured Operator, not the 80-pull number most guides lead with.
Your budget should be working harder than it is...
Here is the multiplier most serious Endministrators never think to optimize, and it sits underneath every pull decision in this guide. Knowing which pity number actually matters decides whether your Origeometry gets you a finished Operator or a stranded 50/50 loss. Where you fund that pull budget decides how many banners you can actually chase in a version cycle.
Most players buy directly in-game at full retail price, which absorbs platform fees and regional pricing overhead that reduce what lands in your account. For one Endministrator, that gap is manageable on a single banner. For a group of players all funding Chartered banners independently at full retail, that gap compounds into real lost pulls, more forced 50/50 losses left unresolved, and featured Operators missed entirely.

Arknights: Endfield 6-Star Pity FAQs
What happens if you lose the 50/50 in Arknights: Endfield?
You get an off-banner standard 6-star Operator instead of the featured one, and your general 80-pull pity resets to zero since a 6-star just dropped. Your 120-pull featured guarantee counter, however, keeps climbing uninterrupted, because losing the coin flip does not consume or reset it. In practice this means you now need to keep pulling, without another 6-star necessarily dropping, all the way to pull 120 on that same banner to force the featured Operator through the guarantee, which is exactly the scenario that turns an 80-pull budget into a 120-pull one.
Does the Headhunting Dossier count toward the 120-pull guarantee in Arknights: Endfield?
No. The Headhunting Dossier is a free 10-pull reward earned after 60 pulls on a Limited banner, and it must be used on the very next Limited banner or it expires unused. Those 10 free pulls do not add toward that new banner's 120-pull featured guarantee counter, so an Endministrator planning around a Dossier still needs to budget the full 120 pulls of actual spend if they intend to force the guarantee rather than rely on luck. Treat the Dossier as a bonus shot at an early 6-star, not as progress toward the guarantee itself.
Does the 6-star pity formula affect 5-star drop rates too in Arknights: Endfield?
No, the growing pity mechanic is specific to 6-star Operators only. The 8.0% base rate for 5-stars stays flat throughout a pull sequence and is not affected by how close you are to the 80-pull 6-star pity threshold. What does apply across both rarities is the separate 10-pull guarantee, which ensures every 10-pull batch contains at least one 5-star or higher regardless of where you sit on the 6-star pity curve. The two systems run independently of each other.
Why is the real pity number 120, not 80, in Arknights: Endfield?
Because 80 only guarantees that some 6-star will drop, not which one. The 80-pull threshold is a floor on rarity, and the coin flip at that point can still hand you an off-banner character instead of the one you're actually chasing. The 120-pull threshold is the only number in the system that removes chance entirely and guarantees the specific featured Operator. Any pull budget built around 80 pulls is really a budget for "a 6-star, maybe the right one," while a budget built around 120 pulls is a budget for the Operator you actually want.
