Fission Junrock Echo Ability
The Fission Junrock Echo offers both combat and non-combat utility, making it a versatile 1-Cost option. When its Echo skill is activated, it summons a Fission Junrock that generates a Resonance Effect, healing all nearby friendly units for 2% of their Max HP. This healing effect triggers upon activation and provides a small amount of sustain, particularly useful during downtime or in rotations where minimal healing is sufficient. The skill has a cooldown of 15 seconds and is based on a Rank 5 version of the Echo, ensuring optimal effectiveness in its healing output.
Outside of combat, Fission Junrock can also interact with the environment. When deployed while exploring, it can automatically collect nearby resources such as minerals and plants, providing convenience and efficiency during overworld gathering. While its primary purpose in battle is to offer light healing support, its added utility during exploration makes it a functional and efficient pick for both combat and adventure.
Possible Sonata Effects
Fission Junrock can appear with one of three possible Sonata Effects: Moonlit Clouds, Void Thunder, or Rejuvenating Glow. These effects are determined by the Echo’s drop and cannot be changed once acquired, so it’s important to match them with the rest of your Echo set to activate bonuses.
Moonlit Clouds provides utility focused on energy regeneration and team support. Its 2-piece bonus grants +10% Energy Regeneration. The 5-piece bonus increases the ATK of the next Resonator by 22.5% for 15 seconds after using an Outro Skill, making it effective in rotation-focused team setups.
Void Thunder enhances Electro-based damage. The 2-piece bonus gives +10% Electro DMG. The 5-piece bonus increases Electro DMG by an additional 15% for 15 seconds after using a Heavy Attack or Resonance Skill. This effect stacks up to 2 times and encourages active, damage-focused playstyles with Electro characters.
Rejuvenating Glow focuses on healing and team-wide buffs. Its 2-piece bonus grants a +10% Healing Bonus. When the full 5-piece set is equipped, healing an ally boosts the ATK of all party members by 15% for 30 seconds, offering strong synergy in support-oriented builds that include healing triggers.
It’s important to note that equipping multiple copies of the same Fission Junrock will not contribute to set bonuses. To activate Sonata effects, players must use different Echoes that share the same Sonata type. Matching your Fission Junrock with other Echoes carrying the same Sonata effect is essential for activating the 2-piece and 5-piece set bonuses effectively.
How to Get Fission Junrock & Material Drops
Fission Junrock is a 1-Cost Echo introduced in Version 1.0 of Wuthering Waves. It can be obtained by defeating the Fission Junrock enemy in the wild. These creatures are scattered across various zones and can be tracked using the Guidebook, making them relatively easy to locate and farm. Additionally, Fission Junrock Echoes may be acquired through Tacet Field Cleanups, which offer a chance to obtain Echoes and materials from a variety of enemies.
When a Fission Junrock is defeated, it can drop several types of enhancement materials used to upgrade Resonators and Echoes.

Suggested Characters
Fission Junrock is a 1-Cost Echo that aligns well with Glacio characters, offering a balanced combination of utility and elemental synergy despite its low cost. Its active skill summons a Glacio-based shockwave that deals AoE damage, applying consistent Glacio elemental pressure. This makes it particularly effective in teams where maintaining elemental resonance or enabling reactions is essential. While its damage isn’t exceptionally high compared to 4-Cost Echoes, its low-cost slot leaves room for more powerful Echoes in the lineup, offering flexibility without sacrificing team efficiency.

Frequently Asked Questions (F.A.Q)
What Sonata set does Fission Junrock benefit?
Fission Junrock can be slotted into Glacio-based Sonata sets like Freezing Frost, which boosts Glacio DMG, further amplifying its synergy with Glacio characters.
Can Fission Junrock be used in non-Glacio teams?
While it functions best in Glacio teams, its low cost allows it to be slotted into other lineups when space is limited or elemental application isn’t a top priority. However, it will lose much of its effectiveness outside of Glacio synergy.
Is it worth using over other 1-Cost Echoes?
If your team focuses on Glacio or requires consistent elemental triggers, Fission Junrock is a strong contender. For teams focused purely on raw stat scaling or different elements, other 1-Cost Echoes may be more suitable.
