Survivability is with shield gating. [Brief Respite] + both augur mods gives +230% shields on cast. Since sonar is spammable, each cast of sonar gives 35 x 2.3 = 80 shields. With [Catalyzing Shields] which sets shields to 74, casting Sonar completely fills shields to max which resets shield gate. [Rolling Guard] is OPTIONAL for more safety window and status cleanse. Silence helps with crowd control.

[Natural Talent] makes the cast time of Sonar more bearable. Two amber shards allows you to replace this for [Rolling Guard], [Resonance] or [Sonic Fracture] augments.

[Augur Secrets] and [Streamline] are flexible for [Augur Message], [Resonance], [Sonic Fracture].

If you want full shield restore from sonar cast with just one augur mod on warrame, use an augur mod on a pistol or sentinel secondary.

Helminth Options - always subsume over 4

• Gloom : great option for Banshee as gloom slow makes the 2s stun from silence last much much longer: https://overframe.gg/build/206953/banshee-prime/silent-assassin-gloom-banshee-general-use-steel-path-sister-lich-killer/

• Resonator : Makes survivability trivial by shutting off enemy AI: https://overframe.gg/build/206000/banshee-prime/dance-party-dj-banshee-resonator-dual-augment-steel-path/
