Personally I think it would be fun to have all the skill checks be real-life skill checks.

Or you could go all the way in the other direction, and have the players roll to solve puzzles instead of doing them IRL.

The dex save has nothing to do with size (beyond needing to be Small or larger to deal any damage at all). I assume the Disadvantage was because they didn't see you.

Source? A Commoner has 1d8 hp compared to a cat's 1d4. A cat's AC is 2 higher, but a Commoner's attack modifier is 2 higher. If the Commoner has a club, they're dealing 1d8 damage instead of 1d4, but even without that it's the same damage. A cat can absolutely win if it gets lucky. After all, one in eight commoners have only one hitpoint, but reliably?

Also, I don't think the fight's really comparable, since at low levels randomness matters a lot more. A Commoner is equally likely to have 1 hitpoint as 8. An adult red dragon is 95% likely to have HP from 227 to 286. And likewise, when you're dealing damage, it would be a lot more consistent.

That said, while a cat can't reliably kill a commoner, a party of four cats definitely can, and going up against a large number of weak enemies is not good in general. Also, dragons just get a few abilities, and depending on the DM maybe a few spells that aren't that high level. Going up against human spellcasters is not a great idea.

Call it what you want. By RAW, it's a DC 15 Dexterity saving throw to avoid damage regardless of the size of the falling creature (beyond that if it's tiny it does no damage at all). And that's assuming you're playing with the optional rules for creatures falling on other creatures causing damage.

you made a huge shadow above him, he knew you were coming.

Somehow I doubt it was established that the fight was at noon on the equator until that moment.

And everything is trying to kill you. And I think there was something about them being banished there.

Aren't drow Australian?

Darkness creates a heavily obscured area.

It never actually specifies where the heavily obscured area is. But I think it makes more sense to interpret it as only the area in darkness is heavily obscured. After all, the area behind it depends on the observer, and there's nothing about that what's heavily obscured by darkness depends on where you're standing.

On the other hand, if this just makes everything in that area dark, but still lets light pass through it, you'd still be able to see silhouettes of anyone standing in it, which really doesn't seem like it's heavily obscuring them.

Why don't they just cast Zone of Truth and ask her if she cheated?

But going to a restaurant and buying a loaf of bread is equally unnatural. It's not like that would get them pegged as vegetarians specifically. Also, weapons and armor (metal or otherwise) are unnatural. Adventuring is unnatural. Supernatural powers are unnatural.

I think it's odd that they're not. They're generally portrayed as liking nature, and nature has no problems with animals killing and eating each other. I'm a vegetarian because I care about the individual animals, and I'm not a fan of nature and I would never become a druid unless it's part of overthrowing the natural order.

Source? They just happened to independently start speaking a language that humans did 40,000 years ago?

It shows that one failed that time. I just asked ChatGPT. I can't be sure how original the riddle is. It's possible it copied the description of the double meaning from somewhere. But it looks like it understood it, and based on how LLMs work, there's no reason it shouldn't.

Make an original riddle. Explain the double meaning behind it.

Riddle: I hold many keys, yet open no doors. I sing without voice, yet keep perfect scores. Though I’m struck, I never feel pain; What am I, in sun or rain?

Answer: A piano.

Explanation of Double Meaning:

Literal Interpretation
    “Hold many keys, yet open no doors” refers to the piano's keyboard, which holds musical keys instead of physical keys for doors.
    “Sing without voice, yet keep perfect scores” alludes to how a piano produces sound through musical notes (without a voice) and follows written scores (musical notation).
    “Though I’m struck, I never feel pain” describes how piano strings are struck by hammers to create sound, but, of course, the piano doesn’t feel.

Play on Words
    Keys are often associated with doors, but here, they reference musical notes.
    Scores traditionally refer to results or outcomes, but in this context, they represent musical compositions.
    Struck typically implies being hit and possibly feeling pain, yet here, it refers to the mechanical action within a piano that produces music.

Each line has a figurative layer connected to musical terms, creating a double meaning based on the dual use of “keys,” “scores,” and “struck.”

Orks don't speak English. Whatever they're calling space marines is, by definition, their language's word for space marine.

It can predict that the word "scales" is unlikely to appear near "books". Do you understand what I mean now? Sorry, neural networks can't understand things. Can you make predictions based on what senses you received now?

But they have wings. Maybe it's a kobald that likes riddles.

Why does it have scales but no wings? Also, lots of living dragons don't have flame and breathe lightning, acid, poison, or cold instead.

That's what I was thinking at first, but since when do banks have riddles? Though maybe in-universe riddles are considered top of the line security.

It's more advanced than just syntax. It should be able to understand the double meanings behind riddles. Or at the very least, that books don't have scales, even if it doesn't understand that the scales that a piano has aren't the same as the ones a fish has.

Given that they're immune, you may as well always keep them poisoned, just in case.
