The guarantor system and 5-star agents in Zenless Zone Zero

In Zenless Zone Zero, the guarantor is a system that guarantees to get a 5-star character or amplifier after a certain number of attempts in a signal search. In this tutorial, we will explain how this mechanism works, including the concepts of soft guarantor and 50/50.

In the final section, we will provide examples for different banners so you can calculate the number of attempts and polychromes needed to get the right heroes and weapons.

How the guarantor system works in Zenless Zone Zero

The Guarantor in Zenless Zone Zero determines the number of attempts in a signal search required to guarantee you will get a character, banner, or amplifier of rarity 4 (A-rank) or 5 (S-rank) stars. There is always the possibility of obtaining these objects before the set number of attempts.

Number of attempts for guaranteed acquisition:

• 4-star amplifier - 10 attempts
• 4-star character - 10 attempts
• 4-star banbu - 10 attempts
• 5-star amplifier - 80 attempts
• 5-star banbu - 80 attempts
• 5-star character - 90 attempts

This means that if you don't get a 4-star item after 9 tries, it's guaranteed to drop on the 10th. The same goes for 5-star items, if they don't fall out until the 89th or 79th attempt, they will definitely fall out on the 90th or 80th attempt.

Why know about the guarantor

Knowing the guarantor system allows you to use polychromes and copies more efficiently by knowing how many tries are left before the desired item is guaranteed to drop.

How to know the number of spins before the guarantor

You do not need to manually record the number of items you have received. This information can be found in the banner menu in the "Signal Register" section. All dropped 4- and 5-star items are listed there, which makes it easy to count the remaining attempts before the guarantor.

Drop Probability and Soft Guarantor

Players calculated the probability of dropping characters, amplifiers, and banbu in different banners.

Probability table:

• Banner 5 stars 4 stars 3 stars
• Dedicated channel Characters: 0.6% Characters: 7.05%, Weapons: 2.35% Weapons: 90%
• Channel Amplifiers Weapons: 1% Weapons: 13.125%, Characters: 1.875% Weapons: 84%
• Star cast Characters: 0.3%, Characters: 4.7%, Weapons: 4.7% Weapons: 90%
• Banbu Channeling: 1% Banbu: 15% Weapons: 90%

The game also features a hidden drop system called soft pity, which increases the chance of dropping a 5-star item after a certain number of attempts. In event and standard banners, the chance increases after the 74th spin and reaches 100% on the 90th spin (hard guarantor or hard pity).

50/50 rule: random character rolls

When you drop a 5-star hero in the event search for a signal, there is a 50% chance that it will be a character other than the current banner. If you don't get the hero you want, it is guaranteed to drop on the next soft or hard banner.

Banner Counters and Guarantor Portability

Each banner has its own guarantor counter, which resets when you get a 5-star drop. This rule does not apply to the rookie banner, which disappears after 50 attempts. If a temporary banner expires, its counter is carried over to the next event banner.

Weapon and Ban Banner Guarantor

The weapon guarantee works similarly to Honkai: Star Rail. It has a 75% chance of dropping the desired Amplifier, and if it fails, it is guaranteed to drop in the next 80 attempts. In Banbu Channel, you are guaranteed to get the chosen 5-star helper on the 80th spin.
