The InfestorCaster-based Witch Doctor similar to the Starcraft II unit -
self-titled infestor.
This build is intended to be gear dependent for things like +max mana, +mana regen, +life after kill, +life regen, etc.The infestor is a powerful caster-build, yet vulnerable to attacks. [DoT skills]
Haunt
Grasp of the Dead (GotD)
Poison Cloud Fetish Army [Spam skills]
Fire bats
Poison Cloud (can be spammed) The Passive skills selected carry the potential of up to 80% Damage reduction and -30% Attack damage from enemies [/b] -
before damage reduction gear is taken into account![Passive]
Jungle Fortitude
Bad Medicine
Death Trance Due to the lack of pets, this build relies on ensnaring enemies - GotD & Haunt. Both are powerful DoT's with mid-long range.
Because GotD carries an 8-second cool down I've added the ensnaring runestone to Haunt to stack slow movement of GotD and make ensnaring spammable.
Up to 87% Slow movement! Firebats(Hungry Bats, targeting attack) is the primary spam skill with Haunt as a secondary spam. Poison Cloud acts as a passive spam skill with DoT that also engages the Passive skill Bad Medicine - reduced enemy attack damage by 30%. Poison is runestoned to increase the duration of acid pools, causing bad medicine to activate twice([i]every 3 seconds) for maximum damage reduction length vs mana spent.[/i]
Fetish Army just for additional DoT damage & distractions. Spirit Walk, the panic button with damage potential. Duration, 3-seconds. Enemies are attracted to your "spirit" body, which makes it great for crowd control and evasion.
When you enter spirit walk your movement speed is increased by ~20-15%.
