  "markdown": "Headhunting is Arknights' gacha. A single headhunt costs 600 Orundum or one Headhunting Permit; a 10-pull costs 6,000. Its design predates the HoYoverse pattern and solves the bad-luck problem differently: instead of a hidden ramp and a hard wall, the escalation is printed in the rules text. [[1]](#ref-1)\n\n## Rates and escalation\n\n| Parameter | Value |\n| --- | --- |\n| Base 6-star rate | 2% per pull |\n| Escalation | after 50 pulls without a 6-star, the rate rises 2 points per pull: 4% at 51, 6% at 52, reaching 100% by pull 99 |\n| 5-star floor | a 5-star or better is guaranteed within a banner's first 10 pulls |\n| Cost | 600 Orundum per pull |\n\nBecause the escalation is official, the expected cost is computable exactly from published rules: about 34.6 pulls per 6-star on average, a widely cited community computation. The worst case is 99 pulls. This makes Arknights one of the few games where no part of the pity math relies on community measurement; compare the unpublished soft pity ramps in the HoYoverse games on the [pity system](/wiki/pity-system) page.\n\nThe escalation counter carries over between successive standard banners, but limited, collaboration, and Kernel banners track it independently. [[1]](#ref-1)\n\n## Featured guarantees\n\nThe featured side is weaker than the rate side. On standard banners each 6-star has a 50% chance of being one of the two rate-up operators, with no loss protection and no carry-over: a plain fractional [rate-up](/wiki/rate-up), not a 50/50. Limited banners guarantee that the first 6-star after 150 pulls is a rate-up limited operator, once per banner, and collaboration banners guarantee the featured 6-star within 120 pulls. [[1]](#ref-1)\n\nSince 2024, limited banners add a real ceiling through [Headhunting Data Contracts](/arknights/wiki/headhunting-data-contracts), the game's spark system, which caps a limited operator at 300 pulls.",
