Incarnon Choices
1: Haven Foray vs Paladin Virtue, opt for Paladin Virtue if either you have 700+ energy and/or you don't have overshields. Only opt for Haven Foray if using consistent overshields.
2: Swift Deliverance - gives Incarnon better range and makes landing hits easier, reload speed is a good choice as well, ammo max does basically nothing for Incarnon form.
3: Critical Parallel
Easily an S tier weapon and it's completely self contained able to kill any Steelpath enemy you throw at it.
To make the weapon even better you can remove the 60/60s while having Viral elsewhere (Panzer/Helstrum/Primary Primer/Nourish) and fill the slots with Primed Expel mods, [Galvanized Crosshairs], and or [Accelerated Isotope].
