Build a Loadout

Electrocuting Focus Shots has become a very strong alternative to both swarm clearing Hipster builds and Focused Shot builds aimed at killing high priority enemies. Usual focus builds are designed for killing trijaws and acid spitters with one focused shot, therefore having to skip T1 ammo and T3 magazine size. EFS hits the acid spitter and trijaw breakpoints with its electrical DoT effect, while allowing to take T1 ammo and T3 magazine size. This makes EFS both formidable against high priority enemies, as well as having plenty of ammo for regular swarm clearing, while also providing a strong slowdown effect against tanky enemies (e.g. bulks).
 
To stop electricuted enemies from damaging you or your team while the DoT is doing its work, taking T5 stun is almost a necessity. This locks you out of the fear mod, which is usually quite strong for holding chokes in solo and fearing entire mactera clouds while you take them down one by one with the M1k. To counteract this weakness against large groups of mactera I decided to run cryo grenades. 
 
Since EFS is sufficient at both waveclearing and killing high priority targets, the secondary slot is very flexible. Several White Phosphorus Boomstick builds, Cryo Bolts and even Embedded Detonators or Trifork Volley for its electric synergy could be considered.
 
I decided to go for Cryo Bolts this time, which are a very good support tool. They excel at freezing typically very annoying enemies like brood nexuses, spitballers and naedocyte breeders, that can quickly ruin runs when nobody in a random team is equipped to deal with them. Since pheromone bolts are the most commonly used special bolt, I decided to use electric bolts and try compensating for the lack of IFGs. Electric bolts do a decent job at locking down areas and especially choke points, but usually require 3-4 bolts to somewhat come close to the value of an IFG.
