[Rolling Guard] is a flex slot because I kept the smoke screen ability for quick access to safety.

[Blade Storm] will activate arcane trickery invisibility, just use [Blade Storm] to kill pretty much everything.

[Savage Silence] will help to guarantee [Blade Storm] kills more consistently.

[Seeking Shuriken] is for demolists and acolytes.

Using any primer weapon to spread viral will greatly enhance [Blade Storm]. I prefer Torrid incarnon.
