Bangboo Channel Signal Search Banner Guide in Zenless Zone Zero (ZZZ)

On the Bangboo Channel, Players use Boopon to recruit Signals called Bangboo. The Bangboo are only obtainable through the Bangboo Channel.

Please note: Unlike Master Tape and Encrypted Master Tape, Boopon is not exchangable with Polychrome.

The Bangboo Channel is not immediately unlocked along with the other Signal Search Channels. Players must progress through Chapter 1: Intermission, until you unlock the Turbo Remodeling Shop. Afterwards, the Bangboo Channel will be available under the Signal Search Interface.

Regardless of eligibility, players can still earn and receive Boopons prior to unlocking the Bangboo Channel.

Players can obtain Boopons through the following known methods:

• HoYoLAB Web Events, such as Stock Up
• Signal Shop: 50% Off Bangbuck Exchange (Limit 5 Monthly), Bangbuck Exchange (Unlimited)
• Hollow Zero: Weekly Bounty Commissions, First-Time Investigation Bonuses, Investigation License Rewards
• New Eridu City Fund: Basic, Growth, and Premium Plans
• Turbo Remodeling Shop: Bangboo Level Cap Rewards (Lv. 20, 40, 60)
• Event Rewards

The Bangboo Channel is a Permanent Channel, just like the Stable Channel. However, the S-Rank Signal search terms are significantly different from the rest of the Channels.

Players need to select 1 -Rank Bangboo before Signal Searching on the Bangboo Channel. When an -Rank Bangboo is obtained through Signal Search, it is guaranteed to be the previously targeted S-Rank Bangboo. Once you select an -Rank Bangboo, you can switch targets without resetting the number of Signal Searches, allowing you to retain your guarantee. A step-by-step visual guide is below (click to view the images):

First, select a Bangboo using the "Selected S-Rank Bangboo" icon in the bottom-right corner (1).

From the selection provided (2), select an S-Rank Bangboo of your choice (3). You can change this Bangboo target at any time.

Once you have chosen the Bangboo, it will have a "100% UP" sticker, indicating this Bangboo will be found when Signal Searching an S-Rank. Obtained Bangboo will be coloured in, while Unsearched Bangboo are greyed out. The target Bangboo will be featured on the Bangboo Channel interface until you change it.

The current Bangboo Channel Banner, An Outstanding Partner, will have one new A-Rank Bangboo Signal: Baddieboo. This Signal Search will be permanently available starting from Version 1.3.

Players can review the Signal Search rates at the bottom of this page.

For Version 1.3, only one new -Rank Bangboo, Baddieboo, is added to the Signal Search pool.

The other new -Rank Bangboo in Version 1.3, Knightboo, is a reward from Hollow Zero's new rogue-like gameplay mode: The Mystery of Arpeggio Fault. In this mode, players can expect to fully complete the Core Updates for Knightboo. This Bangboo will be unavailable to Signal Search through the Bangboo Channel.

In particular, the Bangboo Channel only has -Rank and -Rank Signal Searches for Bangboo. You cannot obtain any -Rank or -Rank Agents and W-Engines like other Channels. B-Rank W-Engines are an exception.

You must select a -Rank Bangboo before signal searching on the Bangboo Channel. Whenever you receive a -Rank Signal, it will be the guaranteed -Rank Bangboo of your selection. Players can switch this selection at any time without resetting the number of Signal Searches, allowing you to retain your guarantee progress.

The Signal Searches on the Bangboo Channel, Exclusive Channel, and W-Engine Channel are accumulated separately from each other. This means that you cannot use your Signal Searches from the Bangboo Channel to progress towards a Signal Guarantee on the W-Engine Channel, and vice versa.

You can exchange 1 Boopon to conduct a Single Signal Search, or exchange 10 Boopon for 10 Signal Searches. Based on the cumulative Signal Searches done on the Channel, the game will provide bonuses listed below:

If you receive an -Rank Signal at any time, either before or at the guaranteed amount, your cumulative Searches for the specific Channel will reset back to 0.

Please note: If no Reception Rate increase or guarantee applies, the base Reception Rate will be split evenly among all Signals within the same Rank.
