This is an accessible [Banshee] build for newer players on normal star chart. It has a pretty even stat distribution and allows you to get some use out of her whole kit; however, Sonar and Silence are by far the best abilities here. Sonar will make weapons do solid damage even without full builds, which is nice for levelling weapons and grinding mastery ranks. Silence is a powerful AoE stun that is the core of [Banshee]'s survivability. Feel free to swap [Sonic Fracture] for [Resonance] or [Augur Reach] if you want. Overall, the best word I can use to describe [Banshee] is "servicable," but if you like her aesthetic and abilities, this should work just fine for early and midgame content.
In harder content, this build will start to struggle to survive, so check out this endgame build that uses Condemn https://overframe.gg/build/500547/
