Rush of Essence

Rush of Essence Passive Casting any Spirit spell returns 100 Mana over 10 seconds. Effect stacks, but is not renewed. All spirits must move onward if they wish to return to their origins. There is no going back.

Rush of Essence is a Witch Doctor passive skill, unlocked at level 36.

In-game

Spirit spells include:

• Haunt
• Horrify
• Mass Confusion
• Soul Harvest
• Spirit Barrage
• Spirit Walk

Note that for Haunt and Spirit Barrage, due to the cost of these spells being no higher than the amount restored, this passive effectively refunds the entire Mana cost, allowing them to be cast almost without restrictions.
