Darkroot Dagger Farm hlp plx

I need help on farming for darkroot daggers.
I need a build that is for an assasin because that is the only char that i have that far.
the boss uses dark apostasy as an elite.
I've been thinking about it and one idea ive come up with is
black lotus strike
wild strike
critical strike
moebius strike
twisting fangs
critical defenses
way of the lotus
entangling asp/shadow refuge

ty for an hlp

I seriously doubt you can handle Darkroot with an assassin build, even using a VwK Rit I had to pull him to the priest.

Here is my warrior thread of this boss. Maybe it will give you some ideas.

W/E Darkroot Entrop solo²

Why not:

Golden Phoenix Strike
Critical Strike
Wild Blow
Critical Eye
Critical Defenses
Shadow Refuge
"Watch Yourself!"
Sprint

Just keep "Watch Yourself!" and Critical Defenses up, cycle in Shadow Refuge constantly. Basically:

GPS --> Critical Strike --> Shadow Refuge/Watch Yourself --> Wild Blow

Repeat until boss is dead. He's probably killing your assassin since you have no healing. Another thing you could try is Flashing Blades {e} instead of "Watch Yourself!". Basically you keep critical defenses up and deal damage with Critical Strike.
