Being that this is a stepping stone to the Ignis Wraith, I have adjusted the rank of some of the more expensive mods and replaced any galvanized/primed mods with their regular variants.
Firestorm is also optional; you could remove it for a 2-forma build. Just reduce the rank of any other non-forma mod slot by 2 levels.
Also can substitute either elemental mod with any variant that gives cold or toxin damage. Just make sure you have viral damage.
