I was experimenting with builds in A1 Inferno last night (really tired of the Zombie Bears/Vision Quest and Splinters/CC builds), and I found a good one that kills quickly and safely. Here is the build:
Poison Dart – Splinters
Soul Barrage – Phantasm
Grasp of the Dead – Unbreakable Grasp
Zombie Wall – Unrelenting Grip
Fetish Army – Head Hunters
Spirit Walk – Jaunt
Alternatives for Passives:
Gruesome Feast (+ gold radius gear helps here, as does health from globes).
Grave Injustice may do nicely to give shorter Wall CDs, given that you have some +radius gear.
Jungle Fortitude if you feel you are dying too quickly.
Concept of the build is to keep enemies from reaching you, while making them trudge through several stacks of Phantasm. That is the main trick that lets this build work: Phantasm can stack on itself when cast on the same spot! Depending on your cast speed, you can get 6ish Phantasms in the same spot, stacking for 45% * 6 = 270% weapon damage per second. Combat usually opens with a Zombie Wall, followed by a Grasp and a few Phantasms. After this just watch the health melt off of all the poor souls caught on the other side of that wall. Elite/Champion packs are pretty easily dealt with by throwing down the Wall and Grasp with Phantasms, then (if you can’t kill the pack before the wall expires) using Fetish Army to keep the pack distracted while you throw down a few more Phantasms and burn them down with Splinters.
The only mod I’ve had trouble dealing with (did a few Butcher runs last night) was Mortar. It fires over the wall, and the champs are not slowed much by the Grasp, and it is a build that uses range to its advantage. However, that is what Spirit Walk is thrown in there for: getting the #$%^ out of dodge when you meet a rough pack.
Phantasm does great damage if enemies stay in it, and even if they don’t, it isn’t a terrible kiting skill. Throw some down while running away in front of you, then lead the pack in circles, refreshing the Phantasms along your path.
One thing I am trying to find a solution for is that there are no direct mana/life regen skills in this build as it stands. This can be troubling for kiting, and relying on health globes isn’t really my style. I tried using the health and mana regen Spirit Walk runes, but found that the 2 second duration is just a little too short to get good distance while kiting. Gruesome Feast worked quite well, but again that is depending on Health Globes to drop to be useful.
