Baldurs gate 1 and 2 had a few secret areas and ect around the place. Pillars seems to have none. Anyone found any?

Of course there are secret locations, a whole bunch of them. Secret levers, hidden walls and stashes... Do any of your party have mechnics skill to detect traps? Because if yes, you can also detect hidden objects that way. Usually they're just small, hidden stashes, but every now and again you can find secret levers leading to hidden rooms and passages. Additionally, places like Endless Paths contain hidden treasuries which you must unlock by completing simple puzzles.

Yeah I usually play a rogue as my main, pump mechanics and walk around in stealth mode. Though I haven't really found any significant hidden areas. Only little bits and pieces.
