Swap smite mods depending on faction.
Group enemies (ideally with Ensnare as electric procs are more likely to headshot when enemies are not ragdolled, and electric procs can double dip headshot multipliers)
Build combo up to x12 and then use heavy attack Tennokai while standing to release a big shockwave.
BUIILD BREAKDOWN
Progenitor: 60% electric, we want to maximise electric weighting
[Condition Overload]: +80% damage per status effect. This is NOT capped by the number of unique statuses i.e. with impact, puncture, slash statuses alone you get +240% damage per hit. Paired with a primer such as [Kuva Nukor] or [Epitaph], you can get up to 8 unique statuses for +640% damage per hit. Even without a primer we have about four innate statuses.
Galvanized Steel: boosts crit chance by 110% and crit damage by 120%
Weeping Wounds: +440% status chance at x12 combo.
Blood Rush: +440% critical chance at x12 combo
Primed Smite Grineer/Corrupted: multiplicative to base damage (condition overload) and triple dips procs spread via influence (1.55 x 1.55 x 1.55 = 3.72x)
Galvanized Elementalist: boosts status damage by 80% and status chance by a further 120%
Shocking Touch: adds electric to proc Melee Influence and boosts elec DoT by +90%
Berseker Fury: attack speed - flexible for Primed Reach if you have external attack speed e.g. arcane strike
Discpline's merit: consistently gives tennokai every 4 hits, can also use [Dreamer's Wrath]
