Spiderhorses is what Spiderdragon's eat, mostly.

that is why we did not get them, they are now extinct

pretty sure the previous designers also had fun and liked talking about it

You mean,like, the 4E designers?

 

[Reynard]

They're certainly not going to know a werewolf in humanoid form is not a humanoid on looking at it, right?

Well, this is an entirely different thing, isn't it?

It's literally in the video we're discussing?

This is off topic but is an interesting question: if a player casts a spell on a subject that is immune to or simply can't be affected by the spell, do you tell them that?

I tend to give them a free Arcana roll before they cast. If they succeed, they remember that Creature X is immune to the spell and can do something else instead.

I'd make that a high difficulty check, but "how to figure out someone might not be human, even if they are disguised as such" is the kind of thing I'd expect wizards, rangers, etc., to have discussed, even if actually doing it in the wild under less than ideal circumstances is very hard.

No. The fact that it is secretly a monstrosity is a entirely different situation than what we were discussing.

I honestly don't see the value in not just telling the player.

I think there's value in having some monsters be more mysterious than others, but giving PCs a shot at having read an obscure book about them, etc. But for common stuff -- "you know that goblin is a fey and thus immune to charm person" -- I will.

It's not that it's secretly a monstrosity, it's that it's secretly a werewolf. There will be creatures where PCs just don't know what category they fall into. They don't get that information because they learned a spell that only has an effect on that type of creature. There is no implication you know all the creatures in the universe and their classifications because at some point you gained access to a spell like Hold Person. There will be creatures you just don't automatically know without at least a skill check.
