[Sevagoth] already excels at nuking tilesets with his viral priming + 2 + 1 combo, so an Influence setup on claws felt redundant. This claws build is for a [Sevagoth] playstyle that involves switching to Shadow, quickly doing an ability rotation, getting a couple kills to stack Galvanized mods, focusing down an Acolyte (or another high-priority target that doesn't get popped by your normal combo), and switching back. Exposure flexible for Duplicate.
Since base damage comes from base Sevagoth ability strength and we're spamming heavy attacks, Killing Blow is a nice side-grade from Primed Pressure Point (slightly less damage, but cozier heavy wind-up speed). Probably want to stick with [Primed Pressure Point] if you intend to use this as a hybrid build.
Focus Radon + Galvanized Reflex help keep combo high as we spam heavy, since initial combo only regenerates at 40/s.
Can also proc corrosive if using [Archon Continuity] on [Sevagoth's Shadow] (not on [Sevagoth]). If you're reliably stacking Melee Exposure, consider slotting [Focus Energy] over [Primed Fever Strike] + [Focus Radon] to open up a mod slot. An optimized build would use a Primed Smite faction damage mod, but I usually don't like having to switch them around.
0 forma required with stance mod installed (does not appear on Overframe).
