DM'ing 5e

>hey so i took the class which allows me to have access to a severely limited spell list, but gives me access to invocations so that I can have capabilities beyond that of a bard or even a wizard

>>>WOW FAGGOT YOU WANT TO CAST MORE THAN TWO SPELLS PER SHORT REST HAHAHAHA YOU IDIOT

you should just start including magical auras in the description of the areas

How do I cut this fucker down to size? The cocky little prick is just so entitled to playing and practicing on his instrument. How do I fuck him over for this egregious offense?

Have an assassin cover his lute in contact poison.
Serves the little shitcunt right.

I mean, let's be honest you shouldn't be punishing your players like that

but a fun thing you might get some enjoyment out of doing would be if next time he rolls relatively lowly during a performance, a heckler shows up. Have him dodge a few tomatoes and roleplay the interaction with the heckler, bearing in mind as he does that the crowd is watching his every move. Might be a fun kind of thing to see how his character would react if that's what you're looking for.

It seems like that's hardly the same as just "being another sense." Either way, it's not about whether or not it's easy for the character, since they can theoretically do it forever.

It's about the tone and style of the game.

Now, if the DM is running a Tomb of Horrors type of adventure, the players need all the detection spells they can get. They should spend every round prodding ahead of themselves with 10-foot poles, checking and rechecking for traps every few inches, doing all the most tedious and meticulously annoying practices that were necessary for survival back in the day. With that as the style, the DM might request that at least one player play a character with a decent wisdom score to help everyone have fun not dying.

But, it sounds like the DM is not running that kind of game, and he's realized that the Detect Magic ability is making the game less fun, potentially even for the player who is using that ability. He's really in the best position to judge this, since he can see the entire adventure and has it designed with the players entertainment in mind.

Now, the best move would simply be to talk to the player, and to ask them to choose a different ability, with the explanation that it's making the game a bit of a chore and that it prematurely spoils many of the surprises for the group, and that it's kind of like bringing a flashlight into a Touch Tunnel. He doesn't need to get into the whole "You're attitude is pissing me off" business, because if the DM is sensible and his requests are sensible, the player will either respect the rational decisions of his DM or throw a tantrum and get kicked out of the game.

This up a small, quick interaction with him in the next town. Have the crowd applaud, or have another bard challenge him to a music match, or have a heckler jeer him. Come up with a few different ideas, either just rattle them off as it comes up or roll to see which one happens.

Nothing wrong with the player getting in a little bit of RP, especially if it doesn't take over a session.

>Running a game designed to be fun
>having fun, but want party to be a certain way
>new player obliges
>uses one of his character's abilities in accordance with the rules
>expects it to function
>I allow it to do so, but after a few times he begins expecting it to continue to function

How do I fix this problem?

>banning the Cleric and Druid's best cantrip

You sound like a shit DM.

This.

It's not exactly that they make it no longer a context, but you need to internalize the magic in your thought processes a lot in order to make there still be challenges, which makes it harder to run. This is totally not unique to D&D though, and is often an element of very well-regarded games.

It sounds like that's OP's goal anyway.
