Angry Chicken - Transform into a chicken and do 215% Weapon Damage upon explosion. This ability also has the hidden bonus of granting +15% movement speed as well while in chicken form! The movement speed bonus is a key part of this build. Try and time your chickens to explode at the very end of the 5 seconds so you can take advantage of the run speed for as long as possible.
This has to be one of the most underrated spell currently as it both offers instant DPS as well as movement speed increase!
There are only 3 Witch Doctor abilities that can do damage on the run without pausing and two of them are already very common.
Spirit Walk - Severance 225% Weapon Damage per second. (Jaunt is also an option with this build as that extra 1 second of run speed/invulnerability is huge. Honored Guest if you are mana hungry and healing journey if you need the extra life.)
Soul Harvest - Vengeful Spirit 230% Weapon Damage.
Angry Chicken - 215% Weapon Damage +15% movement speed as well while in chicken form for up to 5 seconds.
Here is one for those that are extremely geared out: http://us.battle.net/d3/en/calculator/witch-doctor#YVdUiX!WTY!..cYbZ
1. Build Requirements 100k DPS unbuffed. (PTV and Provoke the Pack add 35% to your DPS so effectively this becomes a minimum 135k DPS which goes up to 180K+ with 5GF Stack and 200k+ with all of the above and Soul Harvest!)
2. Zombie Dogs Reduced Casting time of 30+ Combined. (This is for killing Elites Efficiently there is an alternative build below that uses zombie bears)
The reason you need 100k DPS for this build is that you need to be able to one shot all mobs with either Soul Harvest or Angry Chicken. Alternating between the two on trash mobs. Sacrifice is for killing elites.
Alternate Build: Zombie Bears and Mass Confusion with Paranoia in place of Dogs and Sacrifice. (This makes the gear requirements much easier to get). The bears/paranoia are for burning down Elites and should be one of the few times you pause during a run.
I have tried this build in A1/A2 with only 50K DPS and it works well. It takes some practive getting used to it but once you get the hang of it its really amazing. For A3 however it will not work efficiently unless you have 100k+ DPS to start. Would love to hear some feedback from highly geared 100k DPS+ paragon level grinders who give this a try.
PS. Depending on how they set the rules in PVP this ability more than likely will end up on every highly rated Witch Doctors Bar as it offers both speed and damage capability. Sadly it is part of a another great spell Hex which offers both CC and +Damage to a single target so we will see Blizzard decides to treat CC in PVP. If they nerf it for PVP then Angry Chicken will be strong if no most likely people will use Hex.
