Agreed! Although I might entertain PCs looking for such a thingHeh, I think I would only make a DC check to locate something if I knew it existed.
Thank you for that feedback, and nice map. It has the feel of a lived in campaign. Ultimately, I want to avoid needing a table and have a simple rule of thumb. I think I land on -Anyway my conclusion is you are definitely in the right ball park for a typical D&D campaign.
About 1/100 people have tier 1 character class-equivalence, with an order of magnitude fewer per tier above that. An Intelligence (Investigation) ability check DC 5*Tier can discover the whereabouts of such an NPC so long as they are not taking steps to avoid being found; add 5 to that DC if the search is conducted in a settlement with fewer than 10,000 inhabitants. Monster Manual stat blocks such as the Mage represent such NPCs in abstract, and are usually sufficient to run them: adding more detail using their character class where required.
