Never show this to my players please.

"So what do you have? "

"A sword!"

"A sword?"

"Yes. And I can hit with it twice as often twice every hour."

"... I'll stick to my spellslots thank you."

"... It sounded better in my head."

Something tells me that this will be the favorite picture of many people… I am not among them of course.

I know it’s a joke, but I'd say "mostly dead" is just when you roll death saves.

No. If we assume that you have to target the wall it would at the very least stop after destroying the wall.

But by RAW, you can’t even cast it on something behind the wall, because you cannot target something (or someone) with a spell if they are behind total cover. Total cover is created by being completely behind an obstacle (like a wall). This counts even if the obstacle is invisible.

Furthermore, if you chose an invalid target for a spell, you still expend the spellslot but there will be no effect. So you'd actually spend a sixth level spell a lot to achieve nothing.

I would not recommend doing it this way, but that’s what the rules say.

Oh definitely. I assume that RAI this is the intention.

Probably. An author once wrote this piece of conversation:

"Wait? You can transform matter. Thats magic." "Your people can use metal to fly over buildings." "Of course they can. It makes perfect sense."

Having a world, where "magic" actually exist raises a lot of questions about some conventional expressions and cultural aspects.

As I have said in another comment, that is RAW not what would happen:

"You can’t even cast it on something behind the wall, because you cannot target something (or someone) with a spell if they are behind total cover. Total cover is created by being behind completely behind an obstacle (like a wall). This counts even if the obstacle is invisible."

Furthermore, because if you chose an invalid target for a spell, you’d still expend the spellslot but there would be no effect. So you actually spend a sixth level spell a lot to achieve nothing."

It’s very much not RAI I'd say and I would likely handle exactly like you described, but the RAW was so wonky that I wanted to make the meme when I found out about it.

Get's transported to a time where all Sphinxes have died.

They are using an official statblock which lacks this ability. The only way the shaman can have it is if the DM added it themself. And since this is a prewrittem module, it really shouldn’t have such oversights, especially since newer, inexperienced DM‘s likely aren’t familiar enough with the rules to know this, which makes it at least decently likely that they’ll just assume everyone can cast stealthily.

Option one sounds a lot cooler and more impressive, but option two sounds funnier.

Very much this. It even feels very "rogueish" to employ that strategy and it’s far from broken, so I don’t see why you would ban it.

What would Konsi do should they have a serious fight? Throw her out?

Not in my presence at least. I'm moreso mocking the meme format, as people keep using it whenever someone brings up that their build only works with thing x. I've seen it with free feats, smites, 1 level dips, specific feats, magic items, …

Some of those takes were reasonable. Some were not. And while the format was made to criticise overreliance on one thing, I feel like it’s sometimes used too easily. Relying on an abilities is not bad in itself. Some builds only work because of abilities. And while it’s fair to bring up that it’s a bit one dimensional, that doesn’t invalidate the build.

As long as the players got to watch and listen, as the two lovebirds did there thing, there would be no reason to complain. You don’t get to see a a high quality romantic comedy show every day.

It is a melee attack. Jesse hits people with the crossbow in melee. Jesse does read the rules. Thank you.

I never said I wanted to exploit it. I just pointed it out because it was very funny to me.

Did the DM just not like Rogues or were they new to DnD?

Ironically enough, I've had campaigns where just doing what the priestess suggested would have been a better solution than what the party ended up deciding to do.

And thats why I think Firbolgs are underused.
