The principe of this build is to only use heavy attack. The damage come mainly from the bleed (slash proc), that is proc all the time by the heavy attack of a [Nikana].(independently of the status chance)

This build kill in 1 hit the Heavy Gunner of the steal path far above the level 200.
(even with Sacrificial Steal and [Primed Reach] not at rank max ; [Pressure Point] instead of [Sacrificial Pressure], and [Smite Grineer] not primed)

With [Life Strike], it is very easy to stay alive.
(just use a [Vitality] on the warframe, and add an [Adaptation] if you want to make it even easier)
You can use a [Daikyu] with the amalgame mod instead. it free a slot for [Gladiator Might], [Killing Blow], or a Riven.

We don't care about the Status chance : the heavy attacks always proc slash. (it can add a 2nd proc, but try to have more status chance is less efficients that lot of other things for this build)
We don't care about elemental damage, it don't increase the slash proc damage.
We don't care about the slash damage, [Buzz Kill] will not increase the slash proc damage.
We can even have negative slash damage on a Riven, it will not reduce the damage of the slash proc.

About [Condition Overload] : the goal of this build kill in one hit, without need to apply status before.
But if you play a warframe that can easily apply status effect, like [Saryn], this mod is a good choice, and can be use instead of [Life Strike] or [Primed Pressure Point].

Use the 2 melee arcane ([Fury] and Strike) will make the build even more efficient. it would be a better upgrade than have a perfect riven.

For a riven, the best stats are (in decreasing order) :
-initial combo (at least 10, to reach 40 with Corrupted charge)
-Cold and Toxin together (to have viral in 1 mod)
-Crit chance
-Damage to greener
-range
-Crite damage
-status duration
-attaque speed
-base damage
