Ne/X Dark Pact

I'm sure this has been tried before, but just to be sure:

Attributes: 12+3+1 blood, 12+3 death,

Aura of the Lich (E)
Dark Pact
life siphon
Blood renewal
Touch of Agony
barbed signet
Dark aura

I'd heard someplace that since aura of the lich halves all damage, it will also halve health sacrificed, so that Dark Pact will not cost 10% of 240 health but 5% instead. If I'm not mistaken, regen/degen still has full effect with AotL as well. Please correct me if I'm wrong.

The idea here is to use both auras and spam dark pact/touch of agony at melee range. Blood renewal and life siphon to regain the health lost from the offensive spells.

Just a build for kicks, would be neat if it worked. Do feel free to comment.

Hmm... I tried something similar to this during the last BWE....to be honest, it was suicide in PVP...just not enough meat to survive...fun for PVE though.
