Last Authlim of the True Lord of Tyranny
I suppose that is actually RAW really. The Detect Noise is specifically called out in the 2E DMG and nothing else. I simply made the inference since the values were the same as for a base thief.So I made the opposite inference. Listen is the only thief skill with with the same mechanic and same starting chance as everyone else so the ones that do not have that power explicitly as a thing that anyone can try seem to be intentional in not doing so. So I inferred things like picking locks and picking pockets are not things that can really be done by the untrained/unpracticed. I IRL certainly would not expect to successfully pick a lock having had no experience even trying to do so.
I made an argument to expand that to Hiding & Moving Silently on r/adnd a year or so ago, but I can see your point, especially regarding locks and traps. Even though both would be effectively a Hail Mary level attempt with only base skills, and likely impossible without tools anyway.
