Echo Cost Planner

How to plan an Echo loadout

1. Lock your Cost 4 Main Echo (skill you will use in combat).
2. Fill two Cost 3 and two Cost 1 slots without going over 12 total Cost.
3. Match sonata pieces toward a 5pc Attribute set on DPS, or Moonlit / Glow on supports.
4. Set main stats first; only then chase CRIT / ATK% substats while farming.

Common layouts

• 4-3-3-1-1 — default for most resonators.
• 4-4-3-1 or other mixes — only if you understand the Cost math; total must stay ≤ 12.
