Chevaliers Armos, Palais de l'Est

The boss of the Eastern Palace is six Armos Knights. They ram Link in a circle and then in a line across. You can beat them just by moving Link to the lower right of the room, facing up, and slashing over and over, but the bow is faster. When one is left, stop using the bow, move to the bottom of the room, and hold the sword out pointing up. It runs into the blade on its own.

Armos grown big. Not just one: six of them come at once. They hop all over the room, so it may be best to get to the middle of the room fast. When only one is left, it hunts Link down with care. Fight back with the bow.
