If you guys have this.
You may wonder what you should keep between Fetish Army or Fetish Sycophants. (or use it both?)
My suggestion is, Go for Sycophants only.
With a good attack speed (1.8 or more attack per second) and Vampirebats.
You can have more than 8 Fetish in a couple seconds. (Actually, I have more than ten of them almost all the times.)
Plus, every time you cast Fetish Army, all Fetish from Sycophants will die.
And those 8 Fetish (If you use Legion of Dagger) are not fast enough to reset the 120 sec (or even 90 sec) cooldown in their 20 sec life time.
This will leave you with no Fetish moment very often, and that effect both your DPS and survivability.
So just use it for Big Bad Voodoo - Slam Dance to boost the damage.
And let the Fetish from Sycophants reduce the cooldown for you.
This way is more effective, unless you want that passive slot to do something else.
