Stat priority: Range>Duration>Strength>Efficiency

Can use [Energy Siphon] if you don't have Arcane Energize

[Constitution] might seem dumb, but it can really come in clutch if you get caught out (the extra range doesn't hurt either).

I use [Conductor] because especially on defense missions it can roll away from the objective, you can substitute it with whatever fits your playstyle, though if you want just pure throughput use [Power Drift] or [Cunning Drift]

You don't need any defensive mods, thanks to your Metronome's nocturne buff, though the Augur set bonus and Arcane [Guardian] do help if you get caught in the crossfire

Though this build has uses 2 formas, you can make it work with none depending on your preferences

I recommend a high tempo song for both primary playstyles because you can quickly activate it if you prefer to afk farm enemies and get back to the show you were watching, or because you don't have to keep track of it if you want to dish-dash all over the enemy while in stealth with a melee weapon.

The build is usable on Eidolon hunts, but look up a more min-maxed one, this is just what I roll with most of the time.

Enjoy!
