Mystic Sandstorm and JQ

I saw a derv run this build in JQ today: Mystic Sandstorm | Dust Cloak | Aura Of thorns | Staggering Force | Death's charge | Vital Boon | Mystic Regen | Sand shards

It looked fun and i gave it a go. It worked nicely as i expected (hoora ). But i was wondering if theres any elite (derv or non-derv) that would go nicely with this build (like maybe another enchant with end-effect)and what to take out for it. I've got no idea rlly, any suggestions or help would be appreciated

Ps: i'm not sure if this is the right place to post this, but i didn't find a JQ/FA section anywhere.

Aura of Displacement

Mes NPCs shatter aura of displacement.

shadow form maybe? i think a saw some1 running that build

Back when I made this build originally I used Shadow Form + Deaths Charge, worked pretty good, the delay between the spikes / chain is somewhat long though and Necromancer's do it far better.

Vow of Silence maybe?

Vos, will make it so that i can't cast enchants om myself, so that would be kinda useless

But after some messing around i've found that Wastrell's Collaps works pretty well.
I can now take down every npc, except the ranger in the main shrines, yay me

ooh.. ride the lightning. that should finish one of the rangers.

I run a similar build that is D/N with arcane zeal as the elite to lower my costs and then after i sandstorm i use poisoned heart to take care of anybody that survived and death nova if im close to dying
