This is pretty much an example of what happens when you get a riven for crit and elements.

The -damage to grineer is not the most desirable, but is easily bypassed by the metric-ton of crit it can fart out, along with corrosive damage.

You can also build this for viral, but the impact deals with the shield so the corrosive just demolishes the health. Either way it works wonders.

If you don't have a similar riven, just go with a Toxin stat, like primed fever strike.

I mostly copied from this build: https://overframe.gg/build/7860/war/red-[[War]](/items/arsenal/1181/war/) (although I prefer attack speed over combo duration since I run [Ash]'s augment which gives 10s combo duration.

TLDR: Crit, crit, crit and corrosive.
