Where do I go when looking for dungeons or cities?

In the game, dungeons feature stone pillars that can be seen from a distance. Walk over to them and then walk below to find a gate that leads to the entry. The cities are blocked by wooden fences, where you need to find the gate.

I’m having trouble understanding what some characters are saying.

Different races in the game speak different fantasy languages. To understand them, you need to read the correct language book, and then it will be translated in-game.

How do I change outfits?

After defeating the first boss, walk over to the wardrobe and activate it to change outfits. All homes in the game have wardrobes where you can switch your outfit.
