I'm playing Witch Doctor and making use of several of the wonderful Intelligence boosts they can get (Gruesome Feast, Soul Harvest...). I need to know when to time these boosts, however, to get the best use of them. So, how does gaining Intelligence affect the following?

  • A Grasp of the Dead in play
  • Corpse Spiders already thrown
  • Monsters already taking damage from Locust Swarm or Haunt
  • and lastly, minions in play, like Gargantuan

This question could be used in general for other classes as well, I just used Witch Doctor as an example.

Unfortunately, you can't see the damage from DoTs. I don't think that part is answerable. –  Raven Dreamer May 18 '12 at 22:25

Not being able to see DoT damage is untrue. Options -> Gameplay -> Display Damage Numbers. –  Klokworkk May 21 '12 at 5:48

I just ran a few tests because I was curious on this and wanted to know myself since I'm maining a Witch Doctor. My findings are as follows.

Testing Method: I used the abilities on a monster (or multiple) and watched damage against them. I removed gear and equipped it while DoTs were ticking on targets, and I also used INT Boost abilities while DoT effects were ticking on targets. To test Spiders I did something similar but had to time it better. I also had no runes active and no passives active. I didn't try to get screenshots, but if you'd like me to redo the test and try to get good screenshots let me know and I'll edit them in.

Scenario 1: Grasp of the Dead - Gaining INT while Grasp of the Dead is already on the ground does not appear to effect Grasp of the Dead's damage. Damage is calculated when spell is cast and damage dealt doesn't appear to change when INT is increased post cast.

Scenario 2: Corpse Spiders (already thrown) - Gaining INT while Spiders are already on the ground does not appear to effect Corpse Spiders' Damage. This was also true for Tiki Men.

Scenario 3: Haunt and Locust Swarm - Gaining INT while Haunt and Locust Swarm are already on a target does not appear to effect Haunt and Locust Swarm's Damage. Additionally, the damage of Locust Swarm bounces ALSO does NOT appear to be effect by INT gains.

Scenario 4: Summoned Pets/Minions - As far as damage is concerned: Damage is calculated for Gargantuan ON HIT. Meaning when he swings at a mob your stats at that moment are the deciding factor on how much he hits. This was also true for Zombie Dogs. I was not able to test if and how INT effects their other stats because I don't know a way to display that information for summoned minions.

Additionally, I also tested if weapon damage being applied changes the situations and all of the above scenarios are still true.

These tests show the following:

1) Damage calculation for persistent effects (DoTs, AoE Damage Pools, Non-Minion Summoned Creatures, and etc) is calculated as soon as the spell is cast and damage is not retroactively applied when the player's stats increase.

2) Damage calculations for minions (Gragantuan and Zombie Dogs) is calculated when that minion hits a creature, thus will gain bonuses for increased INT.

These were all tested on a level 60 Witch Doctor so I can't say if they apply to all classes, but I can probably safely assume they do. I also didn't test how damage is calculated for hired mercenaries, but from the test we can also probably assume it is on hit.

An easy way to test this yourself would be to go into Act 1 of any difficulty (I suggest the highest you can go). Then go outside the first area with INT items unequiped and use abilities on the zombies in that area and then equip them mid fight, and hitting enemies with abilities like Soul Harvest and looking at the damage increase. You can display your damage dealt to enemy creatures by going to Options -> Gameplay -> and Checking "Display Damage Numbers"

Thanks for the science! You're likely to be accepted as your answer seems very thorough, but I'm just going to wait a bit more and see if any other answers crop up. Definitely +1 though –  Snailer May 21 '12 at 12:16
This may have changed due to patch 1.0.3, using the grasp of the dead test, then casting soul harvest, I have seen the damage increase. –  Mike Jun 25 '12 at 13:49
@Mike Interesting. When I get some time I'll rerun the tests. Thanks for letting me know! :D –  Klokworkk Jun 25 '12 at 13:57
Anyone know if this answer is still valid? –  Snailer Sep 16 at 13:33
