Jayber the Mad Scientist - Attacking Compulsion

With this build I was aiming for ~100% uptime of the "Overhaul" state from skill 4, while getting cooldowns lowered and durations extended for turret placement and location adjustments as needed.

Simple rotation, drop a turret, cast 4 to get Overhaul buff. Now keep your two turrets down all the time and they will automatically be enhanced. The cooldown for each turret should be about 10 seconds, while the enhanced zone lasts for about 16 seconds. This means that if you need to move a turret to better placement it's not a big deal, you can de-spawn an existing turret by casting the skill, then casting again to place your new turret.

With the amount of HP and Defense on this build from modules and components you are very, very tanky and so are your turrets. I chose to run two pieces of the Annihilation set for the extra duration buff. The other components I chose for maximum HP bonuses. For the reactor you can choose either duration or cooldown, along with non-attribute skill power boost. I think cooldown will yield better results, but I haven't gotten a good reactor to test it yet.

The last module slot for Non-Attribute Syncytium is also a flex slot for the status immunity gold mods (burn, frost, poison, electric) but you would need to catalyze your red mod slot to be able to fit them. If that's not a concern for your bossing needs don't sweat it.

I'm having a lot of fun with this build, and it's always a good chuckle when people I match up with in dungeons and spec ops are surprised by how much of an area I can clear quickly.
