Poison Dart

Poison Dart is a Poison spell used by Witch Doctors in Diablo III. It resembles the Blow Darts from the second game.

In-game
Darts deal both instant damage and damage over time. The latter effect stacks, but is not renewed.

Runes:

 * Splinters: shoots 3 Poison Darts instead of one in rapid succession (in the same direction), each dealing 110% damage as Poison, but no longer deals damage over time.
 * Numbing Dart: damage type changes to Cold and also Chills the enemies hit, slowing them by 60% for 2 seconds.
 * Spined Dart: damage type changes to Physical and also gain 50 Mana per hit.
 * Flaming Dart: instead of usual effect, deals 565% damage as Fire over 4 seconds; effect stacks but is not renewed.
 * Snake to the Face: instead of a Poison Dart, throws a snake that has a 35% chance to Stun the enemy for 1.5 seconds. Speed and range do not change.

Non-rune enhancements:

 * Carnevil (Legendary Voodoo Mask): Up to 10 Fetishes shoot Poison Darts at the same target every time the Witch Doctor does. The Splinters rune does not increase the number of shots made by the Fetishes.
 * The Dagger of Darts (Legendary Ceremonial Knife): Witch Doctor's and Fetishes' Poison Darts Pierce through enemies and deal 400-500% increased damage.
 * Depth Diggers (Legendary Pants): damage increases by 80-100% (Spined Dart Rune only).
 * Simplicity's Strength (Legendary Gem): increases damage by 25% (+0.5% per rank) and heals the character for 4% of maximum Life per hit (rank 25 bonus).
 * Helltooth Harness Set (Set Bonus for 2 items): damaging enemies with Poison Dart will apply Necrosis, Slowing enemies by 60% and inflicting 3000% damage per tick for 10 seconds. Elemental Damage type is chosen from the highest skill bonus of the character.
 * Helltooth Harness Set (Set Bonus for 6 items): after casting Wall of Death, gain +9000% increased damage for 15 seconds for Poison Dart.
 * Boyarsky's Chip (Legendary Gem): Taunts the first enemy hit for 2 seconds (rank 25 bonus).

Passives:

 * Vision Quest: every damaging hit increases Mana regeneration by 40% for 5 seconds; effect does not stack.
