This is a Strain set mod build that synergizes with your Warframe to do various gimmicks with the spawned maggots.
Kubrow attack animations are usually terrible but the Helminth Charger has a Slash/Toxin attack that scale decently with the Strain set mod bonuses.
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.
