Floor 20 (3)

Make your way to the floor where Zelda can possess a regular Phantom, then return to the lava pit.

Move Zelda onto the lava pit, and hop onto her.

Move to the other side, get off, pick up the arrow director, then get back on her.

Move to the right until you see a ledge with stairs and two of those decorated tiles.

Hop off there, place the arrow director on the right of those two tiles, make it face east, then get back on Zelda, emerging from the lava pit on the east side.

While on Zelda, swing across some wooden poles you couldn't reach before.

Pick up the arrow director, then drop onto Zelda when you move her below.

Place it on the small ledge to the south, make it face west, then get back onto the platform you swung to before. Make sure you stand on the decorated tile.

Get Zelda over to that second arrow director, pick it up, and stand her on one of the decorated tiles.

As Link, fire an Arrow at the arrow director to the southeast. This should hit the eye switch on the other side, opening a door to the west briefly.

Fire an Arrow at Zelda's arrow director and it will hit an eye switch on the other side of the newly opened door, opening another door leading upstairs.

Have Link swing back, move Zelda to Link, make her drop the arrow director, then move both across the lava pit and head upstairs.
