Thoughts on Haunt and rune options Thoughts on Haunt. Cost 98 Mana Unruned: Haunt does 575% weapon damage over 15 seconds. Which is 38,3% weapon damage per second, or 115% weapon damage per 3 seconds. Runed with Resentful Spirit Haunt does 288% weapon damage over 3 seconds, which is 96% weapon damage per second. At first glance Resentful Spirit appears to be a must be Rune for Haunt, dramatically increasing the dps potential, turning the 15 second dot into a 3 second one, with each tick hitting for 2.5 times as much. But the total damage done per mana pent is litterally halved as 575/2=287.5, meaning you have to expend twice the amount of mana to do the same amount of damage. Making resentful spirit far better for bursty pvp when its implemented. Furthermore as Ive understood it, if the haunted target dies, the spirit will for a short time attempt to seek a nearby new target and haunt it, until its 15 duration is expended, which means that even if a haunted target dies early, then the cast is not always wasted as the spirit will latch onto a new nearby victim until it have spent itself, plus multiple haunts can stack on one target. Which makes haunt excellent for dealing with both crowds and tough bosses with high life. Especially so if choosing to rune it with Lingering Spirit to give the spirit more opportunity to find a new target and reducing mana waste when running around and kiting foes that might not always be in range of each other. Haunt gets even more interesting when you look at the Draining Spirit Rune that makes the spirit return 8.17 mana per second. At 12 seconds of survival, a draining spirit will have paid off its entire cost. If a draining spirit lasts the whole 15s duration, you will even have a mana surplus. 122.55 mana returned at 15 seconds passed, which is more likely to come to pass thanks to the seeking ability. And thats not even considering the Witch Doctor's innate mana regeneration or anything from items affecting it. So dont be fooled by the Resentful Spirit rune, the mana efficiency becomes extreme with Draining Spirit and even letting it act as a mana generator to help fuel other expensive spells. Now imagine the potential of using Pierce the Veil passive. PtV gives you a straight 20% buff to damage at the cost of 30% more expensive spells. A Draining spirit would need to survive the entire duration to nearly wholly pay off the cost of itself with PtV chosen. Haunt would pair well with Plague of Toads runed with Toad Affinity to remove mana cost for it and giving you something to spam at close quarters with the damage buff of PtV, and still having plenty of mana left over for anything else. And thats not counting in other mana efficiency passives like Rush of Essence or Blood Ritual.
