The idea of this build is to shut down enemies, so you can dance through them gracefully with a melee weapon, cleaving them in two while jamming out to some music and chilling. I have personally run this build in Steel Path Survival for up to 3 hours with no issues whatsoever. The way it works: Your Shooting Gallery is consistently shutting down enemies, stunning them and jamming their guns, while your 3 also provides a 95% damage reduction to all incoming damage, and reflecting bullets shot at you. Your 4 key has been swapped out for one of various skills (I will list them below with pros and cons) so that you can have an easier time clearing your way through endurance runs, or just casually playing steel path.

You can also utilize shield gating with this build using your [Rolling Guard] as your shield breaks (Usually only against acolytes) and then destroying them. I will link the melee weapon of choice below as well, with a fully set up build for said weapon.

Helminth Ability choices and their uses:
Wukong Defy - Easier shield gating w/ an additional i-frame
Mirage Eclipse - ~250% additional damage to help shred acolytes within your rolling guard i-frame
Rhino Roar - Damage
Khora Ensnare - Lock down acolytes so they can't give you any trouble
Valkyr Warcry - Speed, and slower enemies, obvious reasons why this is useful
Banshee Silence - Pairs nicely with the shutdown mechanics of this build

I personally use [Khora] Ensnare as I find it the most useful.

My weapon of choice (also helps to use Daikyu Amalgam from Rapalolyst for the inherent 3% lifesteal to Nikanas:
