Switch 2 with a helminth augment cuz it is going to troll you.
Not max build but work just fine as long as you're invisible .
No archon shards and easy to access for everyone.

Order:

-> Metronome (3) : and invisible
-> Amp (4) : stay a bit in the radius for the damage boost
-> Mallet (1) : find a good spot where you don't get crossfired by enemies and that can hit everyone.
-> Profit and harvest loot from fallen enemies (health, energy, materials)
