Why Use This Build?

• This build only requires 3 Forma.
• This weapon can easily kill level 150 Steel Path Acolytes and break Nullifier bubbles relatively easily.

How to Use This Build

• Toxin Progenitor is best for innate Viral damage with only Primed Cryo Rounds.
• Aim next to Nullifier bubbles so the bomblets break it instead of the round bouncing off.

Mods

• Vigilante Supplies - Needed to maintain ammo
• Galvanized Chamber - Multishot
• Primed Cryo Rounds - Cold damage
• Primed Firestorm - This dramatically increases the range and increases effective damage (by reducing falloff by 66% because the falloff applies to a larger distance).
• Hammer Shot - More Status Chance for Viral and Critical Damage for better Slash procs.
• Critical Delay - I prefer this over Point Strike due to the higher Critical Chance. The lower Fire Rate is rarely a problem.
• Vital Sense - Critical Damage
• Bladed Rounds - Even more Critical Damage
• Hunter Munitions - This allows scaling into Steel Path because it tends to lack the damage to one-shot tougher enemies like Acolytes.

Arcanes

• Primary Merciless is generally the best option.

Rivens

• Ideal Positive Modifiers: Multishot, Critical Chance, Critical Damage
• Decent Positive Modifiers: Toxin, Cold, Damage, Status Chance, Faction Damage, Reload Speed
• Bad Positive Modifiers: Electric, Heat, Punch Through
• Ideal Negative Modifiers: Puncture, Slash, Impact, Zoom, Weapon Recoil, Ammo Maximum, Damage to Infested, Status Duration

• Mods to Replace: Bladed Rounds or Galvanized Aptitude

Appendix

• This weapon has lower range (7m vs 8m base) and less falloff (70% vs 80%) than Tenet Envoy. This means that the [Tenet Envoy], in terms of falloff and range is a pure upgrade to the [Kuva Zarr] unless you consider the [Zarr]'s bomblets. I have found that the bomblets rarely matter because they explode on walls but they are effective against Nullifiers. The [Kuva Zarr] is also far worse at killing Steel Path Acolytes than the [Tenet Envoy] because the [Tenet Envoy] has higher Slash procs.
