The innate radiation and impact procs on the [Tenet Arca Plasmor] makes it a great choice to build a ton of status. So spawn the Sister with a magnetic based warframe, build it for viral + heat, and slap on hunter munition. This gives us the potential to get upwards of 6 status procs, resulting in [Galvanized Savvy] doing some serious work.

The fire rate is a little slow without shotgun spazz, but with so much CC from the status effects and damage from [Galvanized Savvy], you won't miss it.
