Yeah, there's definitely a "how much enjoyment gained vs. how much time spent" thing that goes into this, and I really don't understand the "entertainment calculus" that goes into a lot of people's thoughts. Particularly when so much is made of reducing the time allegedly "wasted" on combats...so that more of this pix--er, "fine-toothed comb," spend-half-an-hour-meticulously-deconstructing-the-lair stuff can be squeezed in?
I don't know the new rules at all, I'm an old AD&D2e player coming back after a 2 decade break, so it could be that things have changed. But in old games I played the DM may well say ''he's got on really nice boots'' when he is talking about a perfectly normal, but well made, expensive pair of boots. I seem to recall quite a few magic items specifically looking 'nothing out of the ordinary' and at least one particular item we found looking distinctly shabby.
To my mind - and again the new rules may contradict me - this is how it should be. Otherwise what is the point of detect magic?
If you place a magic item in the game as a DM, the thought process is you want one of the players to have it. So why work so hard to conceal it? A cursed item or artifact may be an exception. But either can have a big swing on party dynamics so it makes sense to conceal it or make it harder to find. Or for a cursed item provide multiple warnings. I guess you could have a table or game that is all about randomness and luck of the draw. I guess that would be the most appropriate time to let the dice decide.
Let's say the group finds a corpse and that corpse is wearing a magic item, e.g. his shoes are magical. But nobody in the group mentions they wanna check out the stuff he is wearing. They might just end up giving the corpse a proper burial. Nobody used Detect Magic either. Would you as DM give them hints? Like "Something seems extraordinary about his clothes" or would you just be "Well if they don't want to search a dead body they have to live with not getting the magic item he is wearing"?
