This build uses the Mecha set synergy with your Warframe to nuke large groups of enemies with DoT status procs.
Kubrows have terrible attack animations so no offensive mods of any kind are suggested.
Precept mods have a priority system as shown in the following picture, with 1 being the highest priority and 10 being the lowest priority.

Precepts are placed in their current spots to ensure they're used in the most opportune times. Do not change their positions unless you're confident in how these conditional mods are activated by your companion.
