Presumably each monster has its own resistance stats to different types of damage, such as 5% lightning resistance and 10% holy resistance, much like how the player does, but is there a general pattern to which types of enemies are weak on some kinds of elemental damage? For example, will zombies always generally have low resistance to Holy damage? Is there any sort of additional bonus to attacking a zombie with a holy weapon?

If such a pattern does exist, what are the different monster types(i.e. zombies, fallen, humans, ents, bulls) and their general weaknesses/resistances?

I started by removing my gear to get best controlled answer possible to make my damage not fluctuate so much. I equipped a low level bow to my demon hunter and went to hell act one. There I started my tests on zombies using my elemental arrow since it does the same damage under different element types due to runes. Against the zombies I use Elemental Arrow with no runes as a basic constant. It dealt around 200-300 damage each shot. I then changed the runes to Frost Arrow and electric Arrow. The outcome was the same 200-300 damage. I decided to test my idea on a more diverse group of enemies. I found some carrions and moon clan, repeated the experiment and had the exact same outcome.

I decided to use test on a creature that I was positive had some type of resistances, Inferno Zombies (which are on fire) in the Halls of Agony level 2 in Act 1. I shot the monsters with Fire and it averaged around 160-250 a shot. Electric averaged 200-300, and frost arrow averaged 200-300. I then decided to try to see how this scaled with gear. I equipped some of my gear and went back in to the area. My Fire arrows were averaging around 1,800 while my frost arrows were averaging around 2,800.

As A final test I decided to go to act 2 and hunt down a construct. I found a Chilling Construct and a Burning Construct and shot basic Elemental Arrow (which is fire damage) and averaged for around 2600 damage on the chilling but 800 on the burning. Swapped to the Frost arrow rune and averaged around 1000 damage on the chilling and 2400 on the burning. Then swapped to the Electric Arrow and averaged around 2500 damage on both constructs.

From the test I have gathered that an enemy has a high resistance to the element that it is, but will not have lower resistances to the opposite elements of its type. Also, an easy way to tell what element type a creature is would be by the type of damage it is dealing (example the Constructs stated above.)

  • Nice analysis. Do you have any data about holy damage too? Which enemies resist holy and which instead take increased damage from it?

  • Crossbows tend to have very little damage range, if you perhaps want to retest with one of those. Commented May 23, 2012 at 17:26

    I used a crossbow to test this out a little more, it indeed does have less variable damage, found some Frost Lurkers and came up with the same conclusion. The Frost Arrow deal less damage while the Fire and Electric bolts deal the same damage. I have no way to test Holy damages or resistances, from the test above I would assume that no monster takes added damage from Holy, but I have no way to test this myself

  • @Melini: As I understand the question, it concerns the monster side of things: "What is a monster resistant against and how can the player find out?". The answer you provided concerns the player side: "If I deal holy damage, will I do extra damage against undead monsters". Monster resistances are not mentioned/touched in there.

Here is your answer! It's from the Fansite Q&A the developers did some time ago:

Q. Will weapons with elemental affixes get extra damage against their elemental counter-part (e.g. Holy weapons get more damage against undead)?

No, we don’t want people to feel like they’re forced to carry around a bunch of weapons with each damage type and swap them in and out to remain effective. We actually had it in the game at one point where each damage type had a secondary effect, and we were super excited about it, and then we played it and it just sucked. It sounds super cool, but in practice it just forces too much on the player and makes decisions for them on which types of items are best based on the damage type.


Pure speculation that it's restricted to the harder difficulties, and probably only to rares and elites. I have not noticed any differences in damage in normal campaign, but this is without valid research, only gameplay experience. I have noticed that rares/elites seem to spawn 'elemental' attributes, like fire, cold, or those arcane laserbeam things. Perhaps they have resistances to their own attribute?
