Arknights: Endfield Gacha System Explained

The gacha system in Arknights: Endfield plays a key role in acquiring characters and weapons, but it’s more complex than it might seem at first glance. Beyond the basic drop rates, the game features various guarantees, hidden accumulation mechanics, and limits that directly affect your gacha results. In this guide, we’ll break down exactly how gacha works in Arknights: Endfield: what the base odds are, and what to pay attention to when planning your resource spending.

The most important thing in any gacha game is the pity system. Pity is a special mechanic that ensures you’ll get a high-rarity item after a certain number of pulls. It prevents situations where extremely unlucky players do hundreds of pulls without getting anything valuable.

Arknights: Endfield features different types of pity for characters and weapons. Some pull counters carry over to the next banner, while others reset. The better you understand how pity works, the easier it is to plan your savings and get new characters.

In Arknights: Endfield, the gacha currency is called Oroberyl. A single pull costs 500 Oroberyl, and a ten-pull costs 5,000. The base drop rates for operators of different rarities are as follows:

These base rates determine your chance to get a character with each pull.

Limited-time banners feature special Operators you can only get during a specific period.

Every ten pulls on any character banner guarantees at least one five-star Operator. This guarantee carries over between banners, so if you do six pulls on one banner and four on the next, you'll get your five-star on the fourth pull of the new banner. Unlike some other games, the standard banner doesn't boost the chances for certain epic characters. Everyone has the same odds.

If you don’t get a legendary Operator after 65 pulls, a “soft pity” kicks in. With soft pity, every pull after the 65th increases your chance of getting a legendary by five percent. For example, on the 66th pull your chance goes up to 5.8% instead of 0.8%, on the 67th it’s 10.8%, and so on.

Soft pity keeps stacking until you finally pull a six-star Operator. Then, the counter resets to zero.

Hard pity, which guarantees a legendary, happens on your 80th pull. However, there's a 50/50 system here:

This guarantee also carries over between banners. For example, if you do sixty pulls on one banner without a legendary, you’ll only need twenty more on the next banner to hit the guarantee.

Another unique feature of Arknights is the absolute guarantee for the event character. On your 120th pull, you are guaranteed to receive the limited legendary character from the current banner.

It's important to note:

If you do 119 pulls and don’t get the featured character, once the banner ends, your counter resets and you’ll have to start over on the next banner.

Unlike some other gacha games, there is no system that guarantees the banner character after losing the 50/50. Every legendary before your 120th pull is always subject to the 50/50 rule. The only way to guarantee the event character is to reach 120 pulls.

Endfield has a unique twist: when a new limited banner is released, the two previous limited characters remain in the available pool. If you lose the 50/50 on the current banner, you have a chance to get one of them instead of a standard character.

The chance distribution looks like this:

For spenders or players with a large currency reserve, there’s an additional guarantee at 240 pulls. Here, you’ll get another copy of the banner character. This guarantee repeats every 240 pulls, allowing you to collect multiple copies.

After 60 pulls on a limited banner, you receive a “Recruitment Dossier”, which gives you ten free pulls on the next limited banner. You can only get one per banner, it must be used strictly on the next limited banner, and you can’t save it for future banners—it expires if you don’t use it.

The weapon gacha system works very differently from character pulls. Instead of using Oroberyl directly, there’s a separate currency called Arsenal Tickets.

Arsenal Tickets are awarded for obtaining characters:

Each ten-pull on the character gacha guarantees at least one five-star and nine four-star characters. This means you always get at least 380 Arsenal Tickets per ten-pull (200 for the five-star + 180 for nine four-stars).

You can also exchange Oroberyl for tickets at a rate of thirty Oroberyl for ten tickets, but this is not recommended.

The weapon banner has much higher drop rates than the character banner:

A ten-pull on the weapon gacha costs 1,980 tickets. Single pulls are not available—you can only pull in batches of ten.

The weapon pity system is also different from the character system:

Unlike the character banner, weapon pity does not carry over between banners. If you do seventy pulls and the banner changes, your counter resets. That’s why it makes sense to pull on weapon banners only if you have enough tickets to reach the desired pity.

There is also an extra pity system at the 100th pull called “Arsenal Replenishment”. This gives you a special box that lets you pick any six-star weapon from the pool, except for the banner weapon.

After this, every eighty pulls alternates between giving you the banner weapon and a new “Arsenal Replenishment” box:

You can also buy weapons from the shop using tickets. Limited banner weapons are not available this way. You can only get them through weapon gacha. Standard weapons, including mythic ones, appear in the shop on a rotating basis and can be bought when they're available.
