This is a build I've been playing around with as of late and I think it's loads of fun even if it isn't the most viable. It revolves around using Shadow Bombs to reset cooldowns and generate ammo, therefore leading to even less cooldowns when used with Enveloping Shadows. It requires a slightly different gameplay loop than the typical Vatu build, kind of similar to Buck in that it relies on getting eliminations to reset the Shadow Bombs in order to go in again. When pulled off, you'll be slinging bombs and dashing so often it almost feels like you don't have any cooldowns at all.

It heavily relies on Shadow Bombs, and they need to be landed consistently for the build to work. If you're not confident in your ability to hit the Shadow Bombs, this build can be used with Unerring. However, it is much more effective with Enveloping Shadows so I strongly recommend using that instead.
