OOC:
I deleted my first reply so I could try again ...
While I am cool with that ruling and will abide by it, let me offer a little pushback.
When used with traps, Perception only lets you have the chance to find that something exists. It doesn't tell you want you found, exactly (though often it is obvious), nor does it tell you how it works or if it still functions. It just says, "You see something you didn't expect to see." That would seem to fit within the purview of Perception.
Trap Master also gives you the chance to find traps with advantage if you don't have Perception. It would seem to have a slight overlap because of this, but that's OK because Trap Master does *so* much more. It gives advantage on not only finding a trap, but also on knowing what kind of trap it is, how it works, disabling it without triggering it, and setting up a new trap.
So, yes, there is an overlap between Perception and Trap Master, but it is very specific: the ability to detect traps or the evidence of traps. But each also provides much more that distinguishes between them and makes each quite worthwhile and can be worth it for some characters to have both.
But to show why Perception should be able to detect that a trap exists, let me give two examples.
First, the one that actually happened: When Skeeve say the holes around that one door. That is definitely something he should be able to find using Perception. How they work (e.g. shoot darts, release gas, shoot poisoned darts, etc) would require Trap Master to roll with advantage. But Perception will still let him find those holes.
Second, as a though experiment, think of secret doors. I don't think there is any argument that Perception will let someone find secret doors with advantage. That seems obvious enough. But what about trap doors? I would think that if Perception will give advantage for secret doors, then it has to give advantage to find trap doors. Because, what are trap doors if not just secret doors in the floor instead of the wall.
As a compromise, how about we put it this way: Perception should give advantage to detect anything that can been seen, heard, or smelled. (I am ignoring touch because that's usually what triggers something and taste because, uh, duh.) If that seen, heard, or smelled observation leads one to believe a trap is present, so be it. Or, if a trap has nothing observable (i.e. nothing to see, hear, or smell), then Perception can't find it.
To go back to the first example, Skeeve should definitely have seen those holes using just perception. That it was a trap is incidental. Those holes were an unusual feature of that door and should be noted. It is entirely possible that they were nothing. Or they could have been holes to launch a dart trap (which was the case). But Perception should have definitely allowed him to find those holes. Any further examination of those holes would have required Trap Master to figure out if it really was a trap, what kind of trap it was, and the chance to disable it.
Does that make any sense?
