Stockholm Syndrome in case the converts/hostages don't give enough health.

Standard shotgun setup with flashbang resistance and bag throwing.

A little bit of dodge in case your Grinder isn't paying out immediately. Running and reloading is a Godsend, so use it CONSTANTLY. Silencer skills not only for extra Judge damage but to keep it hidden as well. Not exactly necessary, so points can be used elsewhere if you take off the silencer.
This detection level maxes out both dodge and crit chances without outside (perk deck) help, so no need to ace either.

Because who doesn't want 4 lives?

The Judge - For all your killing needs!
000 Buckshot for highest damage ammo.

Silent Killer Suppressor is best silencer.

Concealment laser.

Mosconi - for when you need to sneak a deadly weapon into a public place.
Dragon's Breath rounds help with hitting large groups of people and kills shields dead.

Road Warrior Barrel

Gangsta Stock

Concealment boosts for each of these will help to make sure you're not spotted.

Grinder deck for the heals. Electric Brass Knuckles to sway converts easier without using ammo. Ammo bag because ammo capacity on these weapons isn't super high.

I'm using the suit to maximize detection and dodge, but feel free to swap silencer skills with armor hiding skills. You'll lose about 5% dodge chance, but the armor could make up for that.

The best part about this setup is that you can sneak missions and still be ready for things if they go south. So not a complete stealth build by far, but you can do a lot without being detected.

Originally, I just wanted a build that relied on crits but found out it's great for setting up Overdrill without having to fight your way into the vault area. Here's a clip of how I use this build to do such. Full run here: https://youtu.be/vBACYNTBNKU
