This is a redux of my old Quassus build, which you can find here: https://overframe.gg/build/556407

This old fashioned bleed-proc build works so well with this weapon that it makes the [Quassus] (in this configuration) the best heavy bleed proc weapon in the game. It is so easy to just hit a single steel path enemy with this weapon and drop them with a devastating bleed-out. The only time in the game this build has been slowed down at all is against liches (who have a cap on how much status effects can hurt them) and against the end-game murmur stuff, who seem to be resistant to bleed somehow. Still though, against the high-level steel path murmur enemies, that just means you might have to hit them a few times instead of once.

The quassus is really unique with this bleed build, because it also throws those daggers, giving you the ability to inflict one-shot bleed procs at range.

And now, with the Prime version, it's even stronger! :D

All of these mods work together. If you want to save forma or avoid using an Umbral forma, you can just use the old build (here https://overframe.gg/build/556407 ), but I went all out to lean into the strengths as much as possible with melee duplicate, [Dispatch Overdrive] (so you'll be boosted all the time), and used an Umbral forma instead of adding a V to [Corrupt Charge] and having to reduce either [Dispatch Overdrive] or [Primed Reach] by a few points. This is probably a good use of Umbral Forma though. It's the best build for it by far, and I actually use my [Quassus] a lot when I'm not using a Naramon build.

Note:
If you don't want to bother with the five forma and using an Umbral and all that craziness, you can totally build this with three forma (don't forma Corrupt charge or the Sacrificial Steel) by adding two V's and replacing the -- with another V. This omits the exilus mod, and put whatever you've got into the arcane slot, if anything. It'll be great.
