General use Stealth based [Ivara] build for staying invisible with Prowl, buffing damage with [Empowered Quiver], nourish for damage boost to weapons and [Artemis Bow] and for energy sustain.

PLAYSTYLE

1. Stay invisible with prowl
2. Cast Eclipse when standing in bright light to 'meshlock' light level with invisibility
3. Shoot dashwire and stay on dashwire
4. Wait for Mecha marking to appear and headshot that enemy to nuke. You will want to use a weapon that has status effects like slash (hunter munitions/internal bleeding) or electric/gas.
5. Can use Artemis Bow if you prefer. Quickshots are vertical and charged shots have a horizontal spread.

HELMINTH

• Nourish - increases energy sustain and gives free viral to weapons including Artemis Bow
• Xata's Whisper- double dips melee stealth multiplier, double dips headshot multiplier, can redirect artemis bow arrows into bubble
• Roar - gives highest status effect damage boost and boost when using galvanized overload weapons
• Silence - add stretch over umbral intensify, prevents eximus and acolyte abilities
• Dispesnary replenishes your entire energy pool even while in Prowl mode, but needs [Equilibrium] over [Mecha Pulse] and requires your pet to run [Synth Fiber].

ARSENAL

If you want to run [Mecha Empowered] and use it to nuke, then you must run this with a kubrow or predasite. Also consider adding Mecha Pulse over transient fortitude:

Remember to silence all your weapons using the silencer exilus mods (e.g. [Silent Battery], hush) so you don't come out of invisibility when you shoot.

Certain strong weapons are innately silent e.g.
Daikyu: https://overframe.gg/build/265600/daikyu/daikyu-internal-bleeding-slash-headshots/
Fulmin: https://overframe.gg/build/280573/fulmin/fulmin-viral-slash-internal-bleeding/
Baza Prime:
Proboscis Cernos:

Artemis Bow uses these builds:
Viral Slash Grineer/Corrupted anti-armor: https://overframe.gg/build/374705/
Corpus Pure toxin: https://overframe.gg/build/374706/

You can also run a STAT STICK for artemis bow because it inherits Fire rate mods and Vigilante bonus as long as it is a NON-BOW primary weapon.
In particular, tenet ferrox primary fire counts as a light source for eclipse, giving maximum damage bonus.
