while the Surface is navigated on foot. Beacons can be set on the map for Link to follow, and save points in the form of statues preserve Link's progress up to that point. During his quest, Link is aided by the sword spirit Fi, who can give hints to the player for both environmental elements and enemies: for example, when an enemy is targeted and Fi is summoned, she will give the enemy's characteristics and weaknesses.
