Basic [Octavia] build that can easily go all the way through the star chart.

1 + 4 for dealing damage over a 35m range.
3 for invisibility (crouch to the beat).
Rolling Guard is your flex slot. It's not entirely necessary, but it's a good safety net.

Don't use Resonator on Defense/Excavation missions.

Use Zenurik focus school for the energy orb effectiveness bonus.

Aura can be whatever you want.
