What are Echoes in Wuthering Waves
In Wuthering Waves, Echoes are collectible, equippable items you obtain from foes, exploration, or events — think of them as “wearable traces” of enemies. Each Echo has base stats, several sub-stats, and one or more unique effects (passives or triggerable bonuses) that alter a Resonator’s playstyle: some grant flat stat boosts, others add on-hit procs, conditional multipliers, utility (heals/shields), or niche counters versus certain enemy types. Echo rarity and class affect their base values and upgrade ceiling, but rarity ≠ Cost—a gold (high-rarity) Echo can still have a low Cost and vice versa.
Why do Echoes matter
- Straight stat boosts: Echoes raise attack, defense, crit, elemental bonuses, etc., so equipping the right main stats gives an immediate power jump.
- Unique mechanics: Many Echoes define playstyles via procs, on-hit effects, or conditional multipliers that can outscale flat stats in the right build.
- Set (Sonata) bonuses: Echoes often belong to Sonatas — equipping multiple Echoes from the same Sonata activates Sonata Effects (typically 2-piece and 5-piece thresholds) that can be build-defining. Balancing standalone Echo power vs. chasing a Sonata set is a core strategic choice.
What is Main Echo
The Main Echo is simply the Echo you place in the top (primary) Echo slot — it becomes your character’s “active” Echo: it grants that resonator specific passive bonuses (e.g., an Elemental/Resonance DMG bonus or other stat boosts) and lets you summon/use that Echo’s unique Echo Skill in combat (many Main Echo skills deal damage, provide utility, or trigger buffs and have their own cooldown).
Choosing a Main Echo is therefore a double-duty decision — you’re picking both the in-battle summon/skill you want available and the slot’s persistent bonuses, so the Main Echo often defines or strongly influences a build (which is why guides list “best Main Echo” choices per character).
What “Cost” on an Echo means
Each Echo carries a Cost value (commonly 1, 3 or 4) that represents how “expensive” it is to equip — you can equip up to 5 Echoes per resonator, but the sum of their Cost cannot exceed your current Echo Cost Limit. That limit is tied to your progression (Data Bank level): early on the cap is lower (e.g., ~10) and it can reach the maximum of 12 once you unlock the required Data Bank milestone, so Cost forces you to pick between a few powerful (high-Cost) Echoes or more lower-Cost pieces to fill slots.
What a Sonata Effect is
A Sonata is a tag some Echoes carry; equipping multiple Echoes that share the same Sonata unlocks Sonata Effects (set bonuses). These set effects activate at specific counts (e.g., 2-piece, 3-piece, or full 5-piece thresholds depending on the Sonata) and can provide powerful, build-defining bonuses, so part of Cost planning is deciding whether to spend points to chase a Sonata set bonus or instead mix standalone Echoes for raw stats.
