"The lowest-ranked members of the Yiga Clan. They've been dispatched all across Hyrule with a single task: seek out Link and end his life. They're a crafty bunch, sometimes disguising themselves as simple travelers or villagers to get the jump on you. Be wary of suspicious people you encounter. They're very agile and carry a bow and a one-handed sword."
The Yiga Footsoldier is an enemy in Breath of the Wild. Just like the Yiga Blademaster, they will randomly teleport to Link after he defeats Master Kohga in the Yiga Clan Hideout (before then, they merely disguised themselves as travelers). As with other Yiga Clan members, they have a strange love for Mighty Bananas. They carry a Duplex Bow, or either a Vicious Sickle or a Demon Carver, the latter being stronger than the former. They teleport around, and each time they shoot their Duplex Bow at Link. A good strategy is to dodge the arrows and then get hits on them before they teleport away, or, alternatively, landing a direct hit to their head will cause them to be stunned temporarily, if they aren't defeated straight away by the shot.
The Yiga Footsoldiers will often disguise themselves as travelers in order to ambush Link. A good way to avoid them is to refrain from talking to suspicious travelers on the sides of roads. A significant portion of them are Yiga Footsoldiers in disguise.
