I felt that I need to create a build based purely on Strain Set so I created the whole configuration to maximize that freak.
Energy Refund per hit let you spam Virulence and Larva and gaining Mutation Stacks. Lower strength means nothing in quicker missions and average duration and range let you use every his skills efficiently, high survivability make him one of the best tank in game.
Thanks to Strain Set the Helminth Charger grows up to 8 Cysts over 24 seconds that erupt every 25 seconds to spawn a maggot. This will create the whole new opportunity to gain Stacks and distract enemies. This will make you and your pet a god damn killing machines, whose strength increases with use.
To complete that Strain Set I created a Venka Prime build based on gaining Critical Chance and Multiplier during the fight so try to not loose that combo counter. Naramon Focus School is here to help you with that.
This is my variation on configuration B. A little bit weaker but more spam-able build for quicker missions. And it use [Nidus] best friend! And it use Nidus Phryke Collection!
Suggested Arcanes are Grace & Guardian.
Suggested Focus School is Naramon for its Power Spike.
