| Vision Quest|
If a Signature spell (Corpse Spiders, Firebomb, Plague of Toads, or Poison Dart) delivers at least one damaging hit, it increases total Mana regeneration by 40% for 5 seconds. This effect does not stack.
Vision Quest is a Witch Doctor passive skill, unlocked at level 40.
The bonus to Mana regeneration is multiplicative to all other similar modifiers. It does not trigger if the spell hits no enemies.
