Heavy 5 forma investment but it hits like a truck, enough to destroy Steel Path enemies. It is very simple to acquire [Condition Overload] stacks; just press E as intended, probably over ~125k DPS with Melee Exposure.

Explanation: Slash weighting is too low, so I had to consider using elemental damage. Rather than using Corrosive or Radiation to battle armor, this [War] instead uses Melee Exposure for a whopping 240% of Corrosive Damage. This opens the chance to equip Viral here instead and free a priming weapon slot. This is a Red Critical build, so I am using [Blood Rush], [Sacrificial Steel], and [Organ Shatter] to maximize Red Critical Damage. I use Berserker's [Fury] to build attack speed as [War] is quite slow otherwise. I would suggest using an Arcane Strike as the cherry on top. I used Condition Overload over Primed Pressure Point due to the high-status chance. Also, Arcane Fury can be considered if you plan to do min-max damage.

Other complimentary stuff to note: Another arcane to consider is Arcane Avenger for the additional critical chance. If you use equip 2-3 Gladiator mods and Arcane Avenger then this build can step into the Tier 4 Red critical zone. For archon shards, I suggest you use Crimson Melee Critical Damage.

12x Heavy Attack Build: [Master's Edge] can be exchanged with [Dreamer's Wrath] for Heavy attack builds. [Organ Shatter] with [Amalgam Organ Shatter]. [Vicious Frost] with either [Focus Energy] or [Reflex Coil]. Melee Exposure with Melee Animosity. This is a heavy attack build, but it costs 1 more forma to use. It is very good on [Kullervo]'s Collective Curse or other who enjoy 12x heavy attack builds.

Enjoy :)
