No, they still need that for Mr. Scruffy.
But detect magic would also determine the types of magic. Red Cloak is the type of person to spend days investigating and understanding a single piece of magic if he couldn't understand how it was working. The moment he detected conjuration he'd start to question why.My two bits:
- Detect Magic would only tell them something is magical. They already knew the dungeons were magical constructs of some sort.
- What they need is Find Traps, which I believe Redcloak has but might not have thought to use. He might be packing a lot of offensive stuff if it's just the 4 of them doing the clears.
- Even if they have find traps, unless they have a high level rogue, it might be difficult for them to do anything about them.
Especially when it's a trap that doesn't seem to do anything.The "trap" is essentially like the old "hide a leaf in a forest" trope. You expect there to be a trap, and you expect there to be magic. But, if you're not actively seeking one right from the moment you set foot in the dungeon, you don't anticipate it.
I’m just saying he’s not the type to go “I detect magic but I don’t see a source. Guess ill ignore it completely and assume it’s nothing.”Magical areas, multiple types of magic, or strong local magical emanations may distort or conceal weaker auras.
And since V was doing it from the other side, he might not have the same interference.
Also, Redcloak might have detected the presence of magic, but if he didn't detect the trap he'd have no way of knowing the line was the trigger, would he? He'd just know the entrance had a magic aura.
