This [Tenet Agendus] build is entirely based on the energy disks launched by the heavy attack. It is a heavy attack spam build, and this is another instance where [Sacrificial Pressure] is just better than [Primed Pressure Point]. I went with Heat in order to convert the weapon's native electricity damage into Radiation, but you can really go for any number of Progenitor elements on this weapon, at least with this build. I don't really see any one progenitor element as being fundamentally better than all the others. Given that every heavy attack is going to be launching projectiles, [Primed Reach] isn't really needed, which means we have a second elemental mod slot, which means we can do all sorts of combination elements in whatever manner we see fit, depending on what faction we're about to be up against. On this build I've just used Viral as a default, but actually that's probably the one damage type I'll never use on the [Tenet Agendus]. Viral is fantastic paired with slash procs, which this weapon can't generate, but for heavy attack spam Corrosive or Magnetic are more useful.
