Edit August 2020: replaced Corrosive with Viral

This build is for Viral/heat but you can freely change the status mods if you want another combo. The Atomos has built-in fire so you can get Gas / Magnetic with only 3 status mods. With three 60/60 mods you can get up to 58.8% status chance at the cost of damage. Don't bother with other status, Viral/heat is where it's at

[Jolt] is a Baro exclusive. For a real Poor Man's Atomos, you can get the same overall damage (but more balanced between Corrosive and Heat) with Convulsion / Pistol Pestilence / Scorch.

Frostbite is T3 spy / kuva spy reward, so no need to wait for Baro anymore!

You can use regular Target Cracker / [Pistol Gambit] for a 3 forma build.
