MASSIVE DAMAGE, RIP PROFIT TAKER, Archgun's Lanka.
Radiation + Cold for Eidolons and Profit Taker (Atmosphere mode)
Corrosive + Heat for most general uses (including Atmosphere mode)
For Railjack, Advised to go for Corrosive + Cold
Archwing mission ...... It DOMINATES the whole archwing chart even in SteelPath
[Shell Rush] can replace the 3rd elemental mod if you want to charge faster, or replace [Critical Focus] (Rad + Cold Build) for faster Profit Taker takedown
Note: In Atmosphere mode (Heavy Weapons and Necramech Arsenal), shots do not have an AoE column and do not ricochet.
NOW THATS ALOT OF DAMAGE!! - Phil Swift
