Dark World Smithery ruins, opened by the middle-aged man near the Desert of Mystery
After reuniting the swordsmiths, pick up the locked chest at the Dark World Smithery ruins and carry it back with the Magic Mirror. Bring it to the middle-aged man near the desert entrance and he unlocks it, revealing a Bottle.

Pound the stake blocking the hole (or mirror in from the Dark World), drop down and sprinkle Magic Powder on the altar. The Mad Batter “curses” Link so every magic item costs half as much.
Link starts able to carry 10 Bombs. Each time 100 Rupees have been thrown into the pond, Venus offers an upgrade: six raises of 5 take it to 40, then a final raise of 10 reaches 50 (700 Rupees in all).
Link starts able to carry 30 arrows. Each 100 Rupees thrown in earns an upgrade: six raises of 5 take it to 60, then a final raise of 10 reaches 70 (700 Rupees in all). Once both are maxed, Venus returns further Rupees.
Free the missing smith (a frog in the Dark World south of the Village of Outcasts, ringed by dark boulders) and bring him back with the Magic Mirror. The reunited smiths temper the Master Sword; leave it with them, step away and return to collect it.

Talk to the Flute Boy in the Dark World’s Haunted Grove to receive the Shovel, then dig in the flower patch of the Light World Haunted Grove to unearth his Flute.
Play the Flute in front of the Kakariko weathervane; the bird inside breaks free and will now fly Link to eight Light World spots whenever the Flute is played.
Dark World Bomb Shop (where Link’s House stands in the Light World)
Once the Ice Palace and Misery Mire crystals are won, the shop sells one Super Bomb at a time for 100 Rupees. Walk it to the Pyramid of Power’s cracked wall to open the Cursed Fairy’s chamber.
