1) Structures are any kind of building or structure on a step or with a Quick Path that leads to it other than a Town building.
2) If a structure is on a step or a Quick Path leads to a structure, you can walk into it and pick up a Loot Card. Afterwards, you end your turn.
3) However, if you are forced to exit, you must exit the structure in any available direction and interact with whatever you land on.
4) These structures are dangerous, hiding some vicious enemies. But they are also places of great reward. Travelers often find items of great value within these places, but you may also encounter creatures of that region. Good luck!
