The Light Arrows

In the Mirror Chamber, defeat the continually spawning Black Boes. While wearing the Stone Mask, put on the Goron Mask and punch out the central pillar.

Reflect light onto the far left Sun Face on the wall to make a chest appear with Stray Fairy #3 inside.

Reflect light onto the right mirror of the central pillar, let it charge, then reflect its light into the Sun Block. Open the chest in this alcove for Stray Fairy #4.

To leave the room, charge the left mirror on the central pillar. Reflect its light into the left wall mirror and hold it until the central mirror stops reflecting. Quickly step up and reflect the wall's light into the Sun Block. Exit through the north end.

In the Hot Air Room, put on the Goron Mask and drop off the ledge. Ground Pound the switch, then quickly roll around the turns to reach another switch in time to remove fire around a chest.

Climb up the ladder. Put on the Deku Mask and fly out to the hot air. Charge up, then go left to find Rupees and a chest with Stray Fairy #5.

Return to the room's entrance, fly around the entire way, and open the chest you gained access to earlier for Stray Fairy #6.

Head into the next room to find the Garo Master.

Put on the Bunny Hood and run around to dodge the Garo Master's attacks.

After he attacks, get a single slash in during his brief opening. Repeat this a few times until he is defeated.

A chest spawns containing the Light Arrows. Exit through the southern door.
