Re: WW Ghost Assassin Guide V2.0
It depends on your build and other gear, but generally, yes, shadow skillers are important just because of the number of important kills they have an effect on. Fade, claw block, claw mastery, mind blast, shadow master, venom, and even burst of speed, cloak of shadows, and psychic hammer when you need them.
A full inventory of them isn't necessary and modern ghosts usually use a split inventory between shadow skillers, 3 max damage/xx ar/xx life small charms, and/or 3x ar/ xx life small charms when they can afford them. If you can't afford them, 9x shadow skillers works pretty darn good too for most opponents.
