Zenless Zone Zero Rewards: Polychrome, Tapes & EXP
Zenless Zone Zero rewards can develop Agents, their W-Engines or a Bangboo, as well as fund Signal Search. This guide separates those uses so you can read a Polychrome-and-materials bundle without mixing different EXP systems or ticket types.
Quick answer
Polychrome can become the tape required by a Signal Search channel. Investigator Logs supply Agent EXP, W-Engine Power Supplies develop equipment, and Bangboo Algorithm Modules develop Bangboo. Denny pays progression costs; it does not replace the other resources.[2][3][4][5][6]

| Item or resource | Where it is used | What to check |
|---|---|---|
| Polychrome | Exchange for the intended Signal Search tape | Check the channel before converting. |
| Master Tape | Stable Channel recruitment | Not the same item as Encrypted Master Tape. |
| Encrypted Master Tape | Exclusive and W-Engine channels | Keep the currency for the chosen channel separate. |
| Boopon | Bangboo recruitment | A Bangboo EXP module is not a Boopon. |
| Denny | Agent and equipment progression costs | Budget it alongside the required materials. |
| Official Investigator Log | Agent EXP | Use on an Agent, not a W-Engine. |
| W-Engine Power Supply | W-Engine EXP | Equipment levels are separate from Agent levels. |
| Bangboo Algorithm Module | Bangboo EXP | Leveling an existing Bangboo is different from recruiting one. |
Master Tapes vs Encrypted Master Tapes
Prydwen’s community guide describes Polychrome as currency exchangeable for Master Tapes or Encrypted Master Tapes. Master Tapes serve the Stable Channel; Encrypted Master Tapes serve the Exclusive and W-Engine channels. These channels obtain Agents or W-Engines under their respective rules. A Master Tape reward therefore cannot simply be counted toward an Exclusive Channel plan.[2]
Bangboo recruitment uses Boopons instead. Prydwen’s dedicated Bangboo guide identifies them as the ticket for Bangboo Signal Search. They are a separate recruitment resource, not another name for either Master Tape.[7]
Denny, Investigator Logs and Agent promotion
Denny funds upgrades. Investigator Logs supply Agent EXP: an Official Investigator Log provides 600. Certification Seals instead raise an Agent’s level ceiling and are divided by Specialty; skill chips are divided by Attribute. These materials address different requirements.[3]
Prydwen’s Agent guide explains the benefit of levels: they increase base HP, ATK and DEF. Skill upgrades develop individual actions, while Core Skill upgrades strengthen the corresponding core passive. Receiving Agent EXP does not itself perform those separate skill upgrades.[4]
W-Engine EXP vs Bangboo EXP
Akademiya’s item descriptions give W-Engine Power Supply a value of 600 W-Engine EXP and Bangboo Algorithm Module a value of 600 Bangboo EXP. Despite matching numbers, one develops equipment and the other develops a Bangboo. Neither is Agent EXP, and a Bangboo EXP module is not a Boopon for recruitment.[5][6]
W-Engines provide equipment stats and a passive. Prydwen notes that activating the passive requires a matching Agent Specialty. That makes equipment selection relevant as well as its level: a leveled engine with the wrong Specialty does not activate that matching passive.[8]
Mistaken tape exchanges
HoYoverse allows applications to correct eligible mistaken tape exchanges. Keep the incorrect tapes unused and apply through Feedback > HoYoverse Help Center > Master Tape/Encrypted Master Tape Incorrect Redemption. Approval and eligibility conditions apply; the policy does not convert tapes back to the original currency.[1]
Using the items in a mixed reward
Our advice
For a reward containing Polychrome, Denny and W-Engine materials, make a Signal Search choice and an equipment choice separately. Select the desired channel before exchanging currency. For the equipment project, check that the W-Engine suits the Agent’s Specialty, then inspect its level and Denny requirement. Keep any Investigator Logs for the Agent screen instead of using their quantity as a measure of W-Engine progress.[2][3][4][8]
Reward and resource questions
What is the difference between Master Tape and Encrypted Master Tape?
The cited channel reference assigns Master Tapes to the Stable Channel and Encrypted Master Tapes to Exclusive and W-Engine channels. Choose the channel before converting Polychrome into a ticket.[2]
