Stalfos are skeleton-like enemies that wield two large swords, which they use both to block and to attack.
They have three main attacks. They can quickly swing one sword horizontally, perform a cross-chop with both swords, or raise both swords above their head in preparation for a powerful two-part attack.
How to Defeat
Much like Bokoblins, you must attack from specific directions that are unprotected, requiring good timing and accurate sword slashes.
Also, the Stalfos is defenseless while its swords are above its head, so this is your chance to run around behind it and slash away.
