Fairly cheap no forma build for [Nezha] thats perfect for Railjack.

Duration on Divine Spears is just enough to hack reactor and kill it without being shot at with enough range to hit the entire reactor room.

A nice bonus is that Warding Halo doesnt deactivate when you enter Archwing

Xatas Whisper subsumed to make killing sentients in the Anomaly way easier but its not needed as Blazing Chakram adds 200% bonus damage and you can reset sentient resistance with your amp

Zenurik energy dash is needed to help with keeping energy full as theres not many orbs that drop if youre not killing things. Blazing Chakram does increase orb drop chances though

Obviously can be optimized further with formas but this is a surprizingly effective build with no forma required
