Upgrade order
Resonator level and weapon level first, because they are cheap compared to a full echo set. Then Forte: Resonance Liberation → Resonance Skill → Forte Circuit → Basic Attack on most carries. Healers invert that and put Skill or Forte first if that is the heal button.
- One carry to the current level cap
- Weapon to match
- Forte on Liberation and Skill
- Echo levels after the correct mains are locked
Echo levels are a trap early
A level 25 echo with the wrong main stat is vendor trash. Tune, then level. 1-cost pieces are cheap; 4-cost CRIT pieces are where Shell Credits disappear.
Sequences are not a leveling step
Sequence 0 is the assumed kit. Do not delay echo farming to save for Sequence 1 unless you already have a finished 5-piece and a spare Convene stack. S1/S2 notes live on each build page.
