Any good build for Vampiric spirit?

i am faschinated over the (E) Vampiric spirit enchantment.

it steals up to 45 Extra health from enemy when you cast a spell, but it allso makes them cost 3+ more energy.

is there any good builds for this?

Yes there is, stacked with Dark Aura and Saccing damage spells it can do about 150ish damage. E.g. Dark Aura+Vampiric Spirit+Jaundiced Gaze.

Awaken the Blood + Vampiric spirit + Lifebane Strike = 169 damage in the opening attack (provided ur near the the enemy) then use vampiric Gaze or blood of the aggressor and it very effectivly takes out most enemys (aside from the super buffed ones like the lvl 28, or 30 ones etc.) Great for spiking

I had a rather insane mimicry-echo juggling setup that involved using lifesteal with vampiric spirit and cultist's fervor up at the same time. It was fun.

It was too much trouble keeping track of the recharge/mimicry/echo cycles though, so we didn't use it for long.
