This build and guide were inspired by THeMooN85

The Kuva Bramma is basically a juiced-up version of the Lenz. Arrows explode on impact or can be detonated mid-air with alternate fire.

Like the [Paracesis], the [Kuva Bramma] can be leveled to rank 40 after polarizing it 5 times (Each forma giving an extra 2 capacity).

It is also important to note that using 5 forma on this build is NOT necessary. However, to use a focus lens, you will need a rank 40 [Kuva Bramma]. Also, the smidge of extra affinity is nice.

All Kuva weapons have innate elemental damage. Different progenitor warframes will reward different elemental damage ranging anywhere from 25-60%. The progenitor warframe being the warframe that is used while killing the Kuva Larvling.

Primed and Umbral version of a warframe will give the same element.

Two Kuva Brammas can be fused, consuming one of the Kuva Brammas and buffing the Bramma that has consumed the other one. The new Bramma will feature the original % elemental x 1.1. Thus meaning a [Kuva Bramma] with 55% elemental damage can be fused with any other [Kuva Bramma] and achieve elemental damage of 60%. Note: the Bramma that is NOT being consumed by way of fusion will keep its original name and any forma/orokin catalyst/item level.

For most Kuva weapons it is recommended to pick Toxin as the elemental and so that is the element I chose. However, Radiation and Heat are both very viable for a Kuva Bramma build. Toxin/Radiaton/Heat are all viable on the [Kuva Bramma]. This weapon has been tested with 60% Radiation for the extra damage against armor which is useful especially when running slash and viral.

Weapon Info (From the Wiki):

-Shots explode in an 8.3-meter radius on impact with a surface or enemy, then splits -into 6 smaller bomblets that rain down on the point of impact
-Alternate Fire prematurely detonates the arrow mid-flight
-Heavy Caliber's accuracy penalty is minimal on this weapon
-Explosion and bomblets inflict self-stagger
-Explosion and bomblets have linear damage falloff from 100% to 10% from central impact
-Can benefit from [Firestorm] and [Cautious Shot]

This build was made to combine the best of both worlds. I was caught between running viral ([Primed Cryo Rounds] and Infected Clip) with heat (Hellfire) along with Heavy Caliber or instead of Heavy Caliber, Hunter Munitions. The trade-off being higher base damage with [Heavy Caliber] or 30% chance for slash procs on a critical hit with [Hunter Munitions].

I replaced [Hellfire] with [Hunter Munitions] which removes heat damage but adds the chance to get a slash proc on a critical hit. This allows for a combination of both builds, having both a much higher base damage thanks to Heavy Caliber and the ability to get slash procs which is quite useful on crit-oriented builds.

(If you are wanting to keep viral and heat on the [Kuva Bramma] you can easily use a progenitor warframe that will give the Bramma innate heat instead of Radiation)

[Vigilante Supplies] can be replaced with [Arrow Mutation], the advantage of [Vigilante Supplies] being a 5% chance to enhance Critical Hits from Primary Weapons. [Vigilante Supplies] can also be replaced with any other Exilus mod if you feel you won't need the seemingly infinite ammo that Vigilant Supplies gives you.

[Primed Cryo Rounds] can be replaced with normal [Cryo Rounds] if you don't have the primed version. However, this will stunt the amount of damage the [Kuva Bramma] does due to Primed giving +165% Cold and regular only giving +90% Cold.

Huge thanks to THeMooN85 for being a stepping stone for this build and for all of the useful builds he makes

Buena Suerte, Melooo.
