Monster immunities

I was always wondering how common each elemental immunity actually is, so I started going through the Arreat Summit's bestiary and counting the immunes, as well as marking ones I consider dangerous. Here are my findings. Note that I may have the totals off by a bit; lots of numbers to add = lots of chance for error.

Type	Total	Dangerous
FIRE	 93	16
COLD	119	25
LIGHT	 89	37
POISON	 85	17
PHYS	 15	 2
MAGIC	  8	 0

If you want, I could list what the monsters are and which I consider dangerous in another post. Didn't add it here so as to avoid it looking cluttered.

Re: Monster immunities

Interesting. People always say fire immunes are the most common immunes, and it certainly feels so to me, but these were quite few.

Re: Monster immunities

I think the whole "fire immunes are the most common" idea probably comes from this:
-All fallen variants are fire immune
-Act 1 is pretty much nothing but fallen variants

Re: Monster immunities

The problem with the Arreat Summit's bestiary is that it includes some monster sub-types that only spawn in Normal, and others that don't even spawn in the game. It also doesn't tell you anything about the numbers each sub-species spawn in relative to others. There may be fewer monster types that are Immune to Fire, but those monster types can spawn in far greater numbers for a variety of reasons.

Re: Monster immunities

As far as I can tell, the general trends for immunes were: (criteria being that a large portion of a monster type is immune to it. A single monster of a type is generally ignored for this)

Fire:
-mass annoyance groups (fallen, imps, flayers)
-small, slow moving groups (some zombies, spiders)
-balrogs/venom lords

Cold:
-big or fast melee (corrupt rogues, thorned hulks, vipers)
-spell casters (vampires, skeleton mages)

Lightning:
-Fast attackers (Rogue archers and spear women)
-big melee (scarabs, dune beasts, tainted)
-the more magic-based ghosts (storm casters, gloams)

Poison:
-Objects (lightning spires, turrets, barricades)
-Slow moving things (mummies, sand maggots, defilers, skeletons)

Physical:
-Ghosts and swarms

Magic:
-Greater mummies


EDIT: Eh, might as well post the whole chart.
The dashed lines separate act 5 and the act 5 guest monsters.
