OFC always keep in mind your personal Element Bonus ;)
Also dont forget we cant apply the Bonus here so Elemental Damage Values are not acurate!

I usually build my Sidearms with Radiation to take down Alloy armored threats like Bombards in a quick manor, so no Status needed just raw damage.
But in this case its a 50% Toxin roll going high corrosive to overshadow the 215 Impact cause IPS rules.

[Amalgam Barrel Diffusion] is just a personal preference (gotta roll fast)
Actually makes quite the difference on [Ivara] in Prowl & [Mesa] with Waltz ;)

This is always optional but it can enhance the efficiency and experience of the Builds by a lot.
If you dont use ehm, you can usually get away with 1 Forma less!
There is many options that are benefitial - It is acutally worth it 90% of the time.
