Not sure why its not showing up, but this build has the (not so) impossible Corrosive/Viral damage.

1. Primary Merciless for stacking base damage. These arcanes are made available via Steel Path. You can farm Steel Essence in Steel Path missions, purchase the arcane adapter from Teshen in the Conclave room in any relay.
2. [Galvanized Aptitude] for status and stacking damage.
3. [Critical Delay] and [Vital Sense] for hybrid status + crit damage.
4. Bane mod for the "double dip." (If you don't bane then flex spot)
5. The rest is self explanatory.

If you don't have Galvanized mods then you can replace them with the standard counterpart. Having said that, do yourself a favor and get into some arbitrations and get some. These babies are game changing.
