As we all got a bit nerfed with our Builds in fact of the ias nerf, we also had to get a bug with our beloved Zombie Bears. In my oppinion there just unusable in 1.0.3.
So i decided to try a new Build and i think it really works out.
LM: Corpse Spiders - Medusa Spiders
RM: Spirit Barrage - Phantasm
1: Grasp of the Dead - Unbreakbale Grasp
2: Wall of Zombies - Unrelenting Grasp
3: Spirit Walk - Honored Guest
4: Mass Confusion - Mass Hysteria
Pierce of the Veil
29k Dps (including the 20% Pierce Buff)
11%+ Spirit Barrage on offhand
With the very high amount of slow, you can easily get the 3-stack Phantasm uppon an area and your dps works out very good. Its not comparable with our cookie cutters or zb/vq builds, but actually its the most efficient way to make use of your dmg without ias. The Medusa Spiders and your 2 other slows make kiting very easy and let you get your saferange as far as needed very quickly. I cleared yesterday act2 and act3 with this build as easy as with my zb/vq, splinter or bat/vq build and its an interessting alternative.
