Hollow Zero Resonia Guide for Zenless Zone Zero
This is the Resonia page for Hollow Zero Core Mechanics guide in Zenless Zone Zero (ZZZ)! Including information such as the types of Resonium, how to obtain Resonia, and how to use Resonia in Zenless Zone Zero.
Hollow Zero Resonium Explained
This guide outlines the basic information for Resonium, which are "mild Ether matter polymers" found within certain Hollows. More information on Hollow Zero gameplay can be found in the following guides:
Resonia, or Resonium, provide passive combat, squad, and Bangboo benefits while exploring Hollow Zero. These Resonia are primarily used for the game modes Lost Void and Withered Domain.
How do you Obtain Resonium?
Resonia are a unique feature to Hollow Zero, and as such, it only exists within its game modes Withered Domain and Lost Void.
In the Withered Domain, players can obtain Resonium through Resonium-related Event Monitors, such as the various Bangboo Merchants, Resonia Gacha, or unique Encounter Events. Resonia can also be obtained through fusing four or eight of the same Type.
In the Withered Domain's Withering Garden: Seedbed (or Blitz Mode), players can primarily obtain new Resonia after completing a wave of Enemies, entering a new Battle, or by fusing four or eight of the same Type.
In the Lost Void's Special Operations and Battlefront Purge, players can obtain Resonium through certain Map nodes. Additionally, players can also obtain Affinity Resonia in Friendly Talk nodes.
To obtain new Resonia, players may need to complete several runs of Hollow Zero, as Resonia are often randomized per run. In addition, most Resonia are unique to a game mode, and cannot be collected otherwise. Affinity Resonia works a little differently in this regard, so see the relevant section below for more information.
Types of Resonia
In Hollow Zero, all Resonia generally improve the squad's gameplay, but both the Lost Void and Withered Domain feature Resonium lists unique to each game mode. The only common Resonium Type the game modes have is Affinity Resonia.
Each Resonium also has its own Grade Rank, ranging from B-Rank to S-Rank. In addition, players can also catalyze or fuse Resonia together. Catalyzing will improve the effects (such as increasing the Attribute DMG value or cooldown reduction), whereas fusing Resonia together will make a new Resonium altogether.
Fusing Resonia can only occur in Withered Domain, and happens whenever players gather either four or eight of the same Types of Resonia. In Lost Void, instead of fusing, gathering the same ones will level up your General Gears that share the same Resonium Type.
You can view your current list of collected and unlocked Resonia through the Exploration Collection of each Hollow Zero game mode. If a Resonium has yet to be unlocked, highlighting it in your Collection will tell you what you need to unlock it. Once a Resonium is unlocked, players will be able to encounter it while exploring the Hollows.
Resonia in Different Game Modes
Withered Garden
As of Version 1.7, there are a total of 267 Resonia unique to the Withered Domain. You can obtain all Types of Resonia through Exploration Mode of Withered Domain.
In the Withering Garden: Seedbed, also known as Blitz Mode, you cannot obtain any of the following Resonium Types, as these are exclusive to Exploration Mode:
- Hollow Resonia
- Research Resonia
- Artifice Resonia
- General Resonia
- Bangboo Resonia
In Withered Domain, you can both fuse and catalyze Resonia. Fusion only occurs if you collect enough Resonia of the same Type, whereas catalyzing only improves one Resonium from your current inventory.
Inferno Reap
In Inferno Reap, you can use the Resonia gathered from the Withering Garden to make Resonium Kits. Whenever you complete an Operation in the Withering Garden: Core (Exploration) or Withering Garden: Seedbed (Blitz), you will be given an option to save the Resonium collected that run into a Resonium Kit for the Inferno Reap.
However, Inferno Reap has some restrictions as well. Your Resonium Kits cannot contain any of the following Resonia:
- Hollow Resonia
- Affinity Resonia
- Deployed Bangboo Resonia
If the Kit has any of the above, the applicable Resonia will be removed from the Resonium Kit. You can save up to six Resonium Kits at any time, but only equip one per Inferno Reap run.
As Inferno Reap uses the Resonia collected from Withered Domain, any Resonium Kits will have saved any Catalyzed or Fused Resonia.
Lost Void
In Lost Void, players can use Resonium on either the Special Operation commissions or Battlefront Purge. As of Version 1.7, there are a total of 50 Resonia unique to the Lost Void.
You can only obtain Lost Void Resonia after entering Hollow portals leading you into the following locations on the map:
- "Combat - Resonium" and "Combat - Flawless" nodes
- "Harvest Challenge" nodes
- "Encounters" or "Price Difference" nodes
- "Bangboo Store" nodes
- "Friendly Talk" nodes
"Friendly Talk" nodes only appear after you move onto the next Floor, or if you are just about to fight an Elite or Boss Enemy. In addition, "Friendly Talk" can also feature both Affinity Resonia and/or Bangboo Stores where you can exchange for new Resonia.
Aside from a Resonium's personal bonus, such as its Effects or Catalyzing, they can also do something unique to Lost Void: Level up General Gears. Gears are types of Artifact Equipment that provide additional effects the more you level them up.
By collecting the same Types of Resonia in the same run, you can level up the General Gear with the same Resonium Type. In order to progress in an Investigation Strategy's Explorer Badge level, you will need to finish a Lost Void run with at least Level 3 on a General Gear.
As the various Floors of Lost Void are randomized, players can speak with a unique NPC, Marlene in "Friendly Talk", to refresh the whole map. While this can be fully randomized, she can also help you specify a specific area map based on the Location Cards you gather during the run. For example, you can request she refreshes the map to one with the shortest route via the Location Card: Shortcut.
Refreshing the map can possibly help players if they are trying to obtain as many Resonia in a run as possible. By using a route with the most Bangboo Stores and/or Gear Coin-related nodes, you can refresh the Store's stock of Resonia in order to get the Resonia you want. Refreshing the Bangboo Store often requires a type of currency: typically Gear Coins, but it can use the Squad's HP limit as well.
For additional information on Gears, consult the Lost Void guide below:
Affinity Resonia
Affinity Resonium is a unique Resonium Type that features in both the Withered Domain and Lost Void of Hollow Zero. When obtained, this Resonium Type specifically adds an Agent's Mindscape Cinema upgrade for the rest of the run. You can obtain multiple Affinity Resonia throughout one run, but each Agent currently only has one Affinity Resonia available.
How to Unlock Affinity Resonia?
To unlock Affinity Resonium, players need to fulfill the following conditions first:
- Obtained the Agent (through Signal Searching or Events)
- Increased the Agent's Trust to Close
- Complete the Promotion Event to Receive Rewards
Players can begin building an Agent's Trust after completing the corresponding Agent's Main Story Commission or Agent Story. Afterwards, they can either send a Trust Invitation to the Agent and schedule a Trust commission, or interact with the Agent in a Trust Event randomly around New Eridu. The rewards, including Affinity Resonium, can be received through the Knock-Knock DMs menu, or through the Partner Archive at Random Play's Workbench.
While it is not necessary to increase an Agent's Trust in order to complete Hollow Zero, it can provide useful bonuses for your squad when challenging the harder difficulties, especially for Agents you primarily play with.
In Withered Domain, you can only obtain an Affinity Resonium in the Rest Areas of a Floor during Exploration Mode, or after clearing a Floor during Blitz Mode.
In Lost Void, you can only obtain an Affinity Resonium in the "Friendly Talk" Map Node after the specific Agent dealt a Finishing Move on the "Combat - Crisis on the Road" node.
