The [Kuva Tonkor] hits way above it's weight. This build can one shot up to level 150 Steel Path enemies in all factions, and doesn't suffer from ammo issues that weapons like the [Kuva Zarr] or [Kuva Ogris] have. As long as you have stagger resistance this build is good for basically all content.

Ideally you will run this weapon along with an ability that buffs weapon damage, such as Roar, Eclipse, Vex Armor, or [Xata]'s Whisper. Roar is an exceptionally good choice because it multiplies the damage of the slash procs, making the weapon scale better into later levels.

Make sure that your [Tonkor] has Toxin as it's valence bonus, but the actual amount of Toxin damage you get isn't too important. Mine only has 38%.

Mod Choices

• Heavy Caliber - The -accuracy helps spread the grenades around from multishot. Along with Firestorm you're dealing damage across a huge area. If you don't like the inaccuracy swapping it for Serration is fine.
• High Voltage/Stormbringer - This gives us Corrosive on our weapon. This deals extra damage against Grineer's armor and against Murmur robotic enemies. If you don't have Nourish in your build or squad or another way of priming Viral, you can swap Stormbringer for Cryo Rounds and High Voltage for Rime Rounds to get a Viral build instead.
• Hunter Munitions - The [Tonkor] deals slash damage on explosion, but has a poor status chance. Since this is a crit build Hunter Munitions helps us apply slash procs more reliably.
• Critical Delay/Vital Sense - This gives us 90% crit chance. Fire rate doesn't matter since you only have one shot.
• Vigilante Supplies - You can cut a forma to skip this. The [Kuva Tonkor] typically will not have ammo issues without it, but this will make sure you don't have to worry about it and gives a small DPS increase from enhancing crits. If you are running into ammo issues without it you can run [Carrier] for your companion.

If you're not running [Primed Sure Footed], Overguard, or some other way to prevent self stagger, you can also replace [Vigilante Supplies] with [Cautious Shot].

Sadly the [Kuva Tonkor] does not scale multiplicatively with [Galvanized Aptitude].

Arcane

Primary Merciless gives extra damage and a Reload Speed bonus at max rank. Since you're reloading after every shot this is a DPS increase too.
