Updated version of my original kompressa build that I use with my Yareli. Innate viral means you can mod for corrosive and heat and one of the combined elemental mods to maximize [Galvanized Shot].

A few notes:

1. This is actually a 3 forma build, since you can now swap polarities with exilus slots. Overframe doesn't have that functionality added in yet.

2. [Magnetic Might] and [Accelerated Isotope] are mostly interchangeable here. It is up to you whether you want the extra crit damage or fire rate. Both provide an additional element for [Galvanized Shot], but magnetic is probably more useful as an actual damage type.

3. I dropped the riven from my original build because the riven disposition for new weapons is too low. We'll see how high it gets in the future.

4. My [Yareli] can get this to deal orange crits without secondary enervate, so leaning into crit damage with [Primed Target Cracker] is a solid option. Without external crit chance, it is a less effective choice, even at 16% base crit chance. 1.8x base crit multiplier just isn't quite high enough to be worth modding for crit chance. With [Magnetic Might] and [Tenacious Bond] from my panzer, it's a bit more worth it.

5. If you would like to lean more into status damage, you can replace [Primed Target Cracker] with [Pistol Elementalist]. As mentioned in my original build, [Kompressa] is still bugged for [Yareli] while riding Merulina, in that the heat damage doesn't build up like it should. So if you use this with [Yareli], you want to focus more on the upfront damage, as opposed to the status damage. For other frames, status damage is probably the better option since the base crit multiplier is still a bit low.
