This build will be even stronger if you add Viral to the enemy with Companion or other weapons.

Build Explanation

First, Cernos Prime has special effects.The game states.

UNIQUE TRAIT: Deals x1.5 Damege on headshots. The direction of arrow shooting can be switched between vertical and horizontal.

From this description I thought it would work well with headshot related mods.So I included it in this build because I thought it would work well with [Galvanized Scope], a mod that increases CRITICAL CHANCE when you kill an enemy with a headshot.

2,[Galvanized Aptitude]

Hmm... I can't explain it...
I'm including [Galvanized Aptitude] because if you add a condition with other weapons or peds ([Epitaph], [Panzer Vulpaphyla], etc.), the damage will go up by that amount. Also, it has a higher expected value than [Serration].

3,[Galvanized Chamber]

barrage are justice.After all, a barrage... Bulletstorms solve everything... !!!!I don't need to say more...

4,[Vital Sense]

The CRITICAL MULTIPLIER is extended, which leads to firepower. Also, as we will talk about later, if you have RivenMod, replace it with CRITICAL MULTIPLIER.

5,[Malignant Force] & [High Voltage]

These two mods create a CORROSIVE attribute. We will talk more about why CORROSIVE later.

6,[Hellfire]

[Hellfire] is a handy armor value reduction. I would only include it as an extra.

7,[Vigilante Fervor]

[Vigilante Fervor] is a mod that increases the firing rate. The question that may come to mind is, “Why not use another mod that increases the rate of fire?” I will tell you why when I explain the next mod.

8,[Vigilante Supplies]

[Vigilante Supplies] is a mod that does ammo conversion. This alone will eliminate running out of ammunition to some extent.And there is one more effect, and that is the ability to enhance criticality with a 5% chance.This is where the [Vigilante Fervor] mentioned earlier comes into play.[Vigilante Fervor] is a good choice because when worn with [Vigilante Supplies], it increases the effectiveness of the critical enhancement mentioned earlier from 5% to 10%. So I put [Vigilante Fervor] in the slot for the firing rate increase mod. (Sorry if I didn't explain it well)

Reasons for choosing Corrosion and Heat for the status effect

1.The first reason is to use Corrosion and Heat to remove armor values. By removing the armor value, the amount of damage inflicted on the enemy is increased.

2.The second reason is to facilitate the effects of Primary Deadhead.
First of all, Primary Deadhead is not triggered by a damage kill with Slash Dot.So the effect is not triggered unless the kill is by direct damage. Unlike Slash Dot, direct damage cannot ignore armor values. Therefore, Corrosion and Heat are used to remove the armor value of the opponent to make it easier to kill with direct damage.

ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー

Candidates for Arcane

1.Primary Deadhead
Excellent with [Cernos Prime]! Honestly, Primary Deadhead is the strongest in this build if you can do headshot kills.

2.Primary Merciless

・Notes on using Primary Merciless!
When using Primary Merciless, change the Status Effect from Corrosion and Heat to Viral and Heat, or keep Viral and change the Heat slot to [Hunter Munitions] and use Slash Dot. When using Primary Merciless, it is stronger to use Viral and [Hunter Munitions] rather than Corrosion and Heat.

Riven Mod and Contents

Riven Mod changes the mod to be changed depending on the content. If the Riven Mod contains critical damage, replace it with [Vital Sense], if it contains fire rate, replace it with [Vigilante Fervor], etc. Please make your own decision and replace the Riven Mod depending on its contents.
I've included a list of the winning effects in [Cernos Prime]'s Riven Mod

Positive content (+effect)

1.Critical Chance

2.Critical Damage

3.Fire Rate

4.damage

5.Punch Through

A final word from Rito.JP_Tenno

I'll try to keep this short because I'm not very good at explaining things and I'm writing this through a translator (Deepl Translate).
Continuing from the previous issue, this time we considered the build of [Cernos Prime]. The previous build was somewhat unwieldy and unsatisfactory, so I did a bit of research and explained it as a different build this time.I hope this build has been helpful to you and the many kind Tennno's who have read this far.

Have a good Tenno life!
