Slight spoilers ahead for the beginning of the game.

I'm at the moat house where the giant frogs pop out and there's a hidden bandit in the courtyard. I had my rogue sneak around, but no matter how many times I search the area it won't detect the hidden enemies. Am I doing something wrong or is the game just rude like that?

After a bit of digging I learned that Search checks will not reveal hidden enemies. Instead, the game automatically rolls Spot checks, using the Wisdom stat, against the enemy's Hide.

Hopefully this is helpful to anyone else who was having the same challenge I was.
