Hello there
Here is the skill build (need to use elective mode):
Only 2 elite packs skipped:
Illusionist Reflects Damage Electrified Waller Spearmen, found at entrance of Arreat Crater Level 2
Electrified Vortex Fast Avenger Shadow Vermin (vortex combined with ultraspeed pretty much made it impossible)
Here is a video with the playstyle +some elite-boss kills
