Turn right, so that you\u2019re heading south, and gust-glide across the icy gap. Turn left and kill the construct in the room with the broken floor above. Ascend to one of the sections of broken floor at the edge of the room (don\u2019t ascend in the middle of the room, as that\u2019ll take you back to 1F). <\/p>
Head south and grab a piece of broken masonry before turning the corner, where you should see a cog-like mechanism hanging from the ceiling. Attach the masonry block to the mechanism, then use it to turn the mechanism until the gate opens. It\u2019ll shut again immediately, but that\u2019s. Switch to your Recall ability, set the mechanism to rewind, then climb the ladder and go through the gate when it opens again. Climb another ladder and gust the third lock.<\/p>
