Inspired by this question: what are the most and least resisted damage types for Pathfinder 2e? What about weaknesses? (This question precedes the release of Bestiary 3, but it seems to me that Bestiaries 1 and 2 would probably establish a strong enough trend that it would hold with the third.)
This is available, in somewhat incomplete form, for Bestiary 1
While I'm not aware of a source that has done this analysis for all currently printed creatures, an enterprising individual on Reddit manually combed through Bestiary 1 to work this out for that book. Their analysis comes with some qualifiers, namely:
- Positive and Negative damage was not considered, due to the large numbers of creatures immune to each.
- Alignment based damage was not considered, due to being subject to GM discretion.
- Weapon damage types were not considered, as many weapon resistances have built in means to bypass them.
Recreating the table of the post's data below, we see that:
- Fire is most commonly resisted, while Force and Sonic are least commonly resisted
- Poison is by far the most common immunity, while Sonic and Force are the least common immunities
- Fire and Cold are the only significant weaknesses, and are similarly common
Fire is the most resisted, Sonic the Least*
*of the typical "energy damage types".
Someone on Reddit pulled data from PF2e Easytools to compile this massive spread sheet. This includes all monsters released as of March 2021. Here is the relevant information from the Resistances, Immunities, and Weaknesses section:
*I doubt that positive and negative damage here include the whole living vs undead category, but most instances of positive damage I've seen specify "positive damage to undead" so it might be a bit of a moot point (there could be positive damage that affects everyone, as far as I know).
**I am unsure if this includes the tally of mindless creatures or not. It seems like there might be more than 158 mindless creatures out of the 1911 published, but maybe not.
***This doesn't seem to account for alignment based immunities (i.e. all evil things are innately immune to evil damage), but only for special exceptions to the rule. That makes some sense, as the GM can fairly easily change creature alignment on a whim.
So as you can see from all of that, Fire is going to be a very interactive damage type. Poison and Mental are strictly inferior damage types, Force and Sonic seem to be strictly superior damage types, and make sure to grab a cold iron bludgeoning weapon!
