Condition Overload - It Increases overall damage when proc status effects
It just like a [Pressure Point] stacking on itself
Using [Kuva Nukor] is highly recommended so that u can spread viral to increase slash damage
and at the same time bring more different elemental status effects to boost [Condition Overload]
Damage.
we have 3 damage types in our [Orthos], impact puncture and slash
so, [Condition Overload] will stack like this, 3 x 120% = 360%
and with a [Nukor] we can get 4 damage types 4 x 120% = 480%
that means we total of 840% damage boost from [Condition Overload] alone.

WHY SLASH???

we all know that slash is the new meta for steel path. so we maximize the damage we get from slash with viral from [Kuva Nukor].

with 10 stacks of viral from the [Kuva Nukor] we can get
additional 325% damage to enemy health. slash damage can bypass armor so we dont want to worry about the enemy's effective Heath calculated with armor.

with 10 stacks of viral u can just one shot the enemies if u apply a slash proc in ur hit.

[Weeping Wounds] and [Carnis Mandible] :

As we all know Weeping Wounds is a must Mod for a steel path
cause with [Weeping Wounds] we can proc slash all the time on the enemy.
and because of [Orthos Prime] huge 36% status chance we can proc 2 slash procs in one hit. that is insane right.
[Weeping Wounds] gives 440% additional status chance at max combo counter.

and [Carnis Mandible] increases the chance of procing slash more often . And it also gives additional 60% status chance.

Berserker and Spring loaded blade ( or [Primed Reach] if u can put another forma):

these two mods helps us increase our overall DPS and helps us increase combo counter super fast
Berserker is for the additional 75% attack speed and spring loaded blade or [Primed Reach] for more range to hit multiple targets and close the gaps between u and the enemy.

[Blood Rush] , [Organ Shatter] and [Gladiator Might]:

[Blood Rush] and [Organ Shatter] are must must must must Mods for steel path. These Two mods will increase ur Damage to the next level.
[Blood Rush] is for additonal 660% crit chance at max combo multiplier and [Organ Shatter] for additional 90% crit damage.

with [Blood Rush] and [Organ Shatter] u can increase ur damage like this,
1 + ( 24% 660%) ( 4.2 -1 ) = 6x times the base damage.
think what will happen if we multiply this with what we will get from viral and [Condition Overload].

Gladiator Mod is just my personal preference. U can run whatever u want in there. That is a Flex slot. U could put mods like Smite mods , more range , more speed , combo duration or even [Healing Return]. It depends on what u want.
But Please DON'T put any elemental damage in that slot.
cause it will hinder with our slash procs , resulting in lesser overall DPS to enemy health.

Atlast the stance.
[Shimmering Blight]:

this is the best stance in my opinion . cause this has good speed and mobility and insane multihits
and this stance lands hits on enemy heads 90% of the time. that means it can proc stagger and it will also give
2x headshot damage multiplier. The forward combo is just amazing. it can do a 360 degree with 3 hits on the ememy. if we combine this with the range we have then we can hit so many enemies.

AND WHY [Orthos Prime] ?
Cause this is one of the best weapons i have ever experienced. This is weapon is simply awesome.
There is no reason to drop this weapon. And this weapon will never be vaulted. so it can be farmed anytime . and
this weapon can also be farmed by anyone and can be used if they are just above MR12.

FINAL TIPS: It is better if u carry a [Helios] sentinel with gladiator mods equipped in the [Deconstructor] , U can easily hit red crits . RED crits will increase the damage of ur hits even more. And to say another reason , red crits look super awesome.Also u have to use naramon focus school to keep ur combo counter alive for all the time.

HAVE FUN CUTTING THROUGH ENEMIES LIKE BUTTER WITH THE [Orthos Prime] !!!
