where to go from here? (blade vortex)

ok so im moving on from bladefall poison trap. i have 20ex and might have more depending if i need my chest anymore. i have no idea which forum build im supposed to be following for
Blade Vortex
but im looking to up my damage even higher but unsure if im supposed to do

path finder or assassin

tri curse or low life 2 curse 4 aura

is there something more on the reflect immune side of blade vortex builds? id like to be able to run most map mods without 1shotting myself lol

if anyone can help me out id appreciate it.
yes im aware ill probably need skyforth

note: already own heretics veil, shavs, and cosprei so can sell one or the other to get the skyforth if needed

still need help...

Ci trickster or assassin seems popular.
