Wuthering Waves Echo Main Stats Guide: Best 4-Cost / 3-Cost / 1-Cost Per Role
Picking the right main stat on an echo is the single most impactful build decision in Wuthering Waves. Substats are random — there's nothing you can do beyond filtering by score — but main stats are fixed at drop, so a 4-cost echo with the wrong main stat is dead weight no matter how good the substats roll.
This guide gives you the per-cost, per-role main stat priority. Bookmark it and check before you spend Tuners. Pair it with the Echo Scorer to grade the substats once the main stat passes.
How echo main stats work
Each echo has one main stat that scales as you level it from +0 to +25. The main stat pool depends on the echo's Cost (1, 3, or 4). 4-Cost echoes have the largest pool — including the most powerful stats like Crit Rate, Crit DMG, and Healing Bonus — which is why your single 4-cost slot matters the most.
Main stat pools by cost
| Cost | Available main stats | Max value at +25 |
|---|---|---|
| 4-Cost | Crit Rate, Crit DMG, ATK%, HP%, DEF%, Energy Regen, Healing Bonus, Elemental DMG% | e.g. Crit Rate 22%, Crit DMG 44% |
| 3-Cost | ATK%, HP%, DEF%, Elemental DMG% | ATK% 30%, Elemental DMG 30% |
| 1-Cost | ATK (flat), HP (flat), DEF (flat), ATK%, HP%, DEF% | ATK% 18%, HP% 22.8% |
4-Cost main stat priority
You only have one 4-cost slot, so this is the single most important pick on the whole build. The default rule: double-crit unless the character explicitly wants something else.
| Role | Best | Acceptable | Skip |
|---|---|---|---|
| Crit DPS (default) | Crit Rate / Crit DMG | ATK% (only if crit values lag) | Energy Regen, HP%, DEF%, Elemental DMG% |
| Liberation DPS | Crit Rate / Crit DMG | Energy Regen, ATK% | HP%, DEF%, Healing Bonus |
| Heavy Attack DPS | Crit Rate / Crit DMG | ATK% | Energy Regen, HP%, Healing Bonus |
| Sub-DPS / Buffer | Crit Rate / Crit DMG | Energy Regen (if rotation needs it) | HP%, DEF%, Healing Bonus |
| Healer | Healing Bonus | Energy Regen, HP% | Crit Rate, Crit DMG, ATK%, Elemental DMG% |
Rule of thumb: Crit Rate and Crit DMG are interchangeable on the 4-cost as long as your final ratio lands near 1:2. If your weapon and substats give you 60% crit rate already, slap on Crit DMG. If you're stuck at 40%, go Crit Rate.
Why Elemental DMG% is not on the 4-Cost recommended list
Elemental DMG% on 4-cost caps at 30%, the same as 3-cost. Since you only have one 4-cost slot, "wasting" it on a stat you can get on a 3-cost is a net loss compared to running double-crit. Always put Elemental DMG% on the 3-cost slot, not 4-cost.
3-Cost main stat priority
You have two 3-cost slots. The default plan is one Elemental DMG% + one ATK% — but for some characters running specific Sonata sets, two Elemental DMG% can be better.
| Role | Slot 1 | Slot 2 | Notes |
|---|---|---|---|
| Main DPS (any element) | Elemental DMG% | Elemental DMG% | Two matching Elemental DMG% > one Elemental + one ATK% if your weapon already gives ATK%. |
| DPS with low base ATK weapon | Elemental DMG% | ATK% | Use ATK% when your weapon is HP%/DEF%/ER (rare cases). |
| Healer | HP% | HP% | Healing scales off HP for most healers (Verina, Baizhi). |
| Buffer with no Elemental scaling | ATK% | ATK% | Only when the character's buff scales off own ATK. |
1-Cost main stat priority
You have two 1-cost slots. These are the easiest to optimize because the pool is small.
| Role | Both slots |
|---|---|
| Any DPS / Sub-DPS / Buffer (ATK-scaling) | ATK% × 2 |
| Healer / HP-scaling DPS | HP% × 2 |
| DEF-scaling character (rare) | DEF% × 2 |
Never use the flat main stats on 1-Cost. ATK flat, HP flat, and DEF flat scale poorly compared to the percentage versions at endgame. They're trap options.
Putting it all together: a sample DPS build
For a standard Crit DPS Resonator (let's say a typical Fusion DPS):
- 4-Cost: Crit DMG (or Crit Rate if your weapon gives Crit DMG)
- 3-Cost #1: Fusion DMG%
- 3-Cost #2: Fusion DMG% (if doubling up) or ATK%
- 1-Cost #1: ATK%
- 1-Cost #2: ATK%
Sub-stat goal: 60–70% Crit Rate, 150–200% Crit DMG, 2000+ ATK after buffs. Use the Echo Scorer with the Crit DPS preset to verify each piece hits at least an A grade before committing Tuners.
Common mistakes
- Running Energy Regen on a Liberation DPS's 4-Cost. Most Liberation DPS units have enough ER from weapon + substats. Crit stats give more damage per slot.
- Healing Bonus on a hybrid healer/DPS. Healing Bonus does nothing for damage. If your "healer" is actually a Sub-DPS that happens to heal (like some Sonata 5-piece effects), run Crit DMG instead.
- ATK% on 4-Cost for new players. ATK% on 4-Cost caps at ~33%, while two crit values cap at higher effective damage gain. Only acceptable if your weapon and substats already give 60%+ Crit Rate.
- Flat stats on 1-Cost. Always percentage. Flat is a noob trap.
