A/E Solo Shadow Army (NM)

I thinked on Ascalon Warrior's E/A build for some time then I had an idea to turn it to A/E. It is pretty nice:
Shadow Arts:12-3-1
Fire Magic:12
Radiant armor+superior shadow arts rune+others attunement
Any Staff would be ok or if you want +5energy(or %10 halves skill rehcarge) exe or sword of enchanting+fire focus
Shadow Form-Fire Attunement-Glyph Of Elemental Power-Meteor Showe-Bed Of Coals-Lava Font-Flame Djinn Haste-Inferno

First attack the group at left of rastigan. Wait about 10-20 second to leaving shadow warrior and shadow beast to come cack. Before entering battle cast fire attunement and shadow form. Then go near shadow monk other foes will come near. Cast every skill meteor shover to inferno left to right. Dont wait on between casting spells cas as fast as possible. After flame djin haste if any foes werent effected of meteor shaower or didnt died run to rustigan they wont follow. When you clear the left of rastigan youll be prety free now.

You can take out the whole shadow army BUT KILLING ABYSSALS ARE PAIN.
If anyone can help killing abbysals would be awesome sometimes when I finish como they got left like a 1 pixel of life.

TY

I just realized a very bad error in this. If you using the skill bar before this you'll have huge after cast delay after inferno so I changed flame djinn haste's and infernos place. First flame djinn haste THEN inferno
