It's not anything that's not a PC. Monsters do exist. Only named ones are considered NPCs.
It sure seems to infer that any creature that is an individual is an NPC. Generic creature or monster doesn't count. But as soon as you make it an individual, it does. The level you want to flesh out the details is up the the DM, but that's the definition. The "C" in NPC = "character", not "creature."Do they become named when the PCs talk to them and find out they have one? (Serious question thinking about my two current parties).
Sure, and if that information/rationale is discoverable within the setting somehow there's no problem at all.And therefore, there might be innate abilities related to spellcasting that allow a NPC to do things with spells that a PC could not. It's exactly the same thing/
And a NPC might be born from a specific blood or a specifc omen that allows him to have innate abilities that a PC will never be able to duplicate.
Possible, sure, but highly unlikely. There's only so many times you can use these sort of variations before it all starts looking like a DM just contriving to keep powers out of the hands of PCs/players.And it might not be a Time Stop, it might be a "Temporal Interrupt" that looks almost the same but with variations, granted because the NPC (and no PC) was born at a moment where time had stopped and is therefore granted special powers over time by the Lord of Time, and even if a PC could cast Time Stop, it would not be exactly the same.
Now you're getting it!That is slightly different, in my example just above, if the PCs figure out the NPC back story, they might understand why he has powers over time that they will never be able to duplicate. What is interesting though, is that they still understand, and might also find weaknesses that they can exploit, etc.
Only because none of the PCs happen to have it. It's a known ability that exists in the setting; and one could argue that Polyjuice Potion is step one towards anyone being able to transform to an animal (or sort-of) for a while.True, but it still does not mean that any wizard's feat might be duplicated by any other wizard. They have inherent strengths and weaknesses, and for example although some could learn to become Animagi, they could still transform into only specific animals. They could not all decide to transform into bears or powerful animals. And note that, from the PC perspective, it's a purely NPC ability.
Hardly surprising, that, as it's entirely built to serve the story first and only.Honestly, it's not a very consistent magic system.
Thus far my Sanderson readings haven't exactly sent me running back for more. Not sure why.Have a look at those developed by Brandon Sanderson, they are way more adaptable as they are designed with balance in mind (although it's novel-type balance and quite different from RPG-balance, at least there is some balance of some kind).
Then what defines the physics of the setting, and what then interprets them to us-the-players/DM, if not the rules?Why? It's a game. The rules represent play. I mean, 5 foot squares alone should be enough to illustrate that everything is abstract. The group as a whole at the table decides what "reality" is in the game. Sometimes that might line up with the rules but it doesn't have to. The rules are just the interface and the participants decide when to use that interface and when not to.
Earlier editions defined everything that wasn't a PC as an NPC as well; but for the purposes of this discussion I think it's worth narrowing it down a bit and splitting out playable-species NPCs from non-playable-species NPCs. I'm calling the latter group "monsters" for convenience.Yeah, this I think is the main point of breaking here.
5e defines NPC's as ANYTHING that's not a PC. The notion of a third type - Monster - doesn't exist in 5e and hasn't existed since 3e at the least. I can't remember how 2e defined things.
The reason I used her was because it's convenient--she was right under the Death Knight creature entry@Sacrosanct - unless deities are a PC-playable species in your game (which would be an interesting take, to be sure!) your example of Llolth is probably not a good one for makng any useful points here: she's a full deity, and therefore can pretty much do anything she damn well likes as an innate ability.
I've never understood the 1e-2e notion of trying to assign class levels to deities.
