AotL dark Aura necro

OK so i have set my N/Mo up to do some 27 hp farming problem is that i cant seem to keep my Blood renewal up enough since it last 10 seconds and has a 10 second recharge...

During that 1 or so seconds it is down i usually end up dying(trying to farm trolls outside droks for exp)

So i was wondering for ne1 that runns this build. Would a 20% enchantment mod on my +5 sword make enough of a difference to cover the problems im having?

BTW for those wondering this is the setup im using

Protective Spirit
AotL
Dark Aura
Blood Renewal
Dark pact
ToA
Balthazars spirit
essence bond

Blood:8+1+3=12
Death:9+3=12
Protection:12

55hp/ 27 after AotL

20% is +2 seconds for BR, +6 for DA and something large for AotL. That should allow you to cast it continuously.

Ok i went ahead and bout me a 19% upgrade... and all i can say is wow... at first i was so amazed at the difference it made that i forgot to keep Protective Spirit up lol...

So for anyone wondering a +enchantment mod is completely necesarry for the build...
