The Biggoron’s Sword stands as the ultimate offensive weapon for Adult Link in The Legend of Zelda: Ocarina of Time. Boasting twice the attack power of the Master Sword and the distinct advantage of being unbreakable, it is often the top priority for players entering the mid-to-late game. However, unlike the Master Sword, which is central to the plot, obtaining the Biggoron’s Sword requires completing a multi-stage trading sequence that spans the entirety of Hyrule and involves several high-pressure timed deliveries.

The Fundamental Stats: Why Biggoron’s Sword is Essential

In the mechanics of Ocarina of Time, damage is calculated based on the weapon's base strength. The Kokiri Sword has a power level of 1. The Master Sword has a power level of 2. The Biggoron’s Sword sits at a power level of 4. This means that most common enemies that take two hits from the Master Sword will fall in a single strike from the Biggoron’s Sword.

There is a common pitfall many players encounter: the Giant’s Knife. Sold by Medigoron in Goron City for 200 Rupees, the Giant’s Knife looks identical to the Biggoron’s Sword but possesses a critical flaw—it breaks after just a few hits against a hard surface or enemy. The Biggoron’s Sword is the "true" version of this blade, forged by the master smith Biggoron himself, and it will never break regardless of usage.

The only trade-off for this massive power is that it is a two-handed weapon. While equipped, Link cannot use his shield effectively. Pressing the shield button will cause Link to perform a defensive stance with the blade, which can deflect some physical attacks but offers no protection against projectiles or magical bursts that a Hylian Shield would normally negate.

Prerequisites for Starting the Quest

Before embarking on the trading quest, certain milestones in the adult timeline must be reached to ensure the path is clear:

  1. Become Adult Link: The quest can only be completed in the future.
  2. Rescue Epona: While not strictly mandatory for the entire quest, Epona is vital for the timed segments. Without the horse, meeting the time limits for the Odd Mushroom and the Eye Drops is significantly more difficult.
  3. Access to Kakariko Village and Death Mountain: Most of the early steps take place in these regions.
  4. Thaw King Zora: You will need Blue Fire (from the Ice Cavern or a shop) to unfreeze the Zora King later in the quest.
  5. Hookshot/Longshot: Necessary for crossing Gerudo Valley if the bridge has not been repaired.

The Complete 11-Step Trading Sequence

1. The Pocket Egg

Travel to Kakariko Village. Near the entrance to the graveyard, you will find the Cucco Lady. Speak to her, and she will give you the Pocket Egg. She explains that she is developing a new breed of miniature Cucco that doesn't crow as loudly.

2. The Pocket Cucco and Talon

To hatch the egg, you must wait until the next morning. You can use the Sun’s Song to speed up this process. Once hatched, you will have the Pocket Cucco. Take this Cucco to the house in the center of Kakariko Village where Talon is sleeping. Stand near him and use the Cucco to wake him up. After he wakes and returns to Lon Lon Ranch, go back to the Cucco Lady. Show her the Pocket Cucco, and she will be impressed by its happiness, giving you Cojiro—a blue Cucco—in return.

3. Cojiro and the Lost Woods

Head to the Lost Woods from Kokiri Forest. From the entrance, take the first left. You will find a pale-skinned man sitting against a tree stump (Grog). He is the son of the master craftsman from Kakariko. Present Cojiro to him. He will remark that the blue Cucco is usually only friendly to "nice people" and will ask you to deliver a special mushroom to the potion shop in Kakariko Village.

4. The Odd Mushroom (Timed: 3 Minutes)

This is the first timed segment of the quest. Grog gives you the Odd Mushroom, which will spoil if not delivered to the Hag’s Potion Shop in Kakariko within three minutes.

Strategy: Exit the Lost Woods, call Epona, and ride across Hyrule Field to Kakariko Village. Do not use the Nocturne of Shadow to warp, as warping often clears the timer and fails the quest in some versions. Head to the regular potion shop, but go through the back door (the one leading to the mountain trail area) to reach the hidden shop where the Old Hag lives. Give her the mushroom, and she will brew the Odd Poultice.

5. The Odd Poultice

Return to the Lost Woods where you found Grog. He is gone. In his place stands a small Kokiri girl. She informs you that anyone who stays in the woods too long becomes a Stalfos. Show her the Odd Poultice. She will demand it back, as it belongs to the forest, and in exchange, she gives you the Poacher’s Saw.

6. The Poacher’s Saw and Gerudo Valley

Ride to Gerudo Valley on the far west of Hyrule. Use Epona to jump across the broken bridge (or use the Longshot). You will find the Master Craftsman standing near a tent. He identifies the saw as his own and trades you the Broken Biggoron’s Sword for it. He suggests that only a master Goron smith could repair such a blade.

7. The Broken Sword and Biggoron

Travel to the summit of Death Mountain. You can reach this by climbing the trail from Kakariko Village. Near the entrance to the Death Mountain Crater, a massive Goron—so large he is part of the mountain landscape—will appear. This is Biggoron. Present the Broken Biggoron's Sword to him. He is willing to fix it, but he has developed a severe eye infection from a recent volcanic eruption. He gives you a Prescription and asks you to get him some drops.

8. The Prescription and King Zora

Go to Zora’s Domain. If King Zora is still encased in Red Ice, use Blue Fire to thaw him. Once he is free, show him the Prescription. He will explain that the ingredients for the eye drops are fresh and provides you with an Eyeball Frog. This must be taken to the scientist at the Lake Hylia Laboratory.

9. The Eyeball Frog (Timed: 3 Minutes)

You have three minutes to get the Eyeball Frog from Zora’s Domain to Lake Hylia.

Strategy: The fastest route is to jump into the water in Zora’s Domain and let the current take you to Zora's River. From there, ride Epona across Hyrule Field toward the south. Avoid the fences and head straight for the Lake Hylia entrance. Enter the laboratory at the lakeside and present the frog to the Professor. He will initially think you are bringing him lunch but eventually realizes it is for the eye drops. He produces the World’s Finest Eye Drops.

10. The Eye Drops (Timed: 4 Minutes)

This is the final and most difficult timed segment. You have four minutes to get the Eye Drops from Lake Hylia to the very top of Death Mountain.

Strategy:

  • Exit the lab and immediately call Epona.
  • Ride across Hyrule Field toward Kakariko Village.
  • Dash through Kakariko and head up the Death Mountain Trail.
  • If you have planted a Magic Bean in the soil in front of Dodongo’s Cavern as a child, you can use the bean platform to bypass the middle section of the mountain climb.
  • Avoid the falling rocks near the summit. Do not stop to fight the Tekktites.
  • Once you reach the peak, talk to Biggoron immediately. If the timer hits zero, the drops spoil, and you must return to King Zora for another frog.

11. The Claim Check and the Final Wait

Upon receiving the Eye Drops, Biggoron uses them and recovers his sight. He takes the broken sword and the prescription, giving you a Claim Check. He tells you that it will take a few days to finish the forging process.

How to wait: You must wait three in-game days. The easiest way to do this is to play the Sun’s Song six times. Once the time has passed, speak to Biggoron and present the Claim Check. He will hand over the completed, unbreakable Biggoron’s Sword.

Advanced Combat Strategies with Biggoron’s Sword

Once you have the sword, your combat style should shift to account for its range and power.

The Reach Advantage

The Biggoron’s Sword has a significantly longer reach than the Master Sword. This is particularly useful against Stalfos and Lizalfos. You can often trigger their AI to attack, step back, and then strike them from a distance where their short swords cannot reach you. For the Dark Link mini-boss in the Water Temple, the Biggoron’s Sword is the preferred weapon because its reach makes it harder for the shadow to mirror your movements and counter-attack.

The Jump Strike

A jump attack with the Biggoron’s Sword (A-button while Z-targeting) deals double damage of a normal swing. Since the base power is already 4, a jump attack hits with a power of 8. This is enough to one-shot almost any non-boss enemy in the game. It is also exceptionally effective against the spirit-form of Ganondorf during the volley of light projectiles; once he is stunned and falls to the ground, a single jump strike with the Biggoron’s Sword deals more damage than a full combo with the Master Sword.

Shield Management

Because you cannot use the Hylian Shield while the sword is drawn, you must learn to "quick-draw." Use the Biggoron’s Sword for the killing blow or when the enemy is stunned, but be prepared to switch back to the Master Sword (via the equipment menu) if you are facing enemies that fire projectiles, such as Octoroks or the fire-breathing Lizalfos in Ganon’s Castle. In the final battle against Ganon, the Master Sword is required for the finishing blow, but the Biggoron’s Sword should be used for the majority of the fight to deplete his health quickly.

Version Differences: N64 vs. 3DS vs. Switch

While the quest remains fundamentally the same across all versions of Ocarina of Time, there are minor differences to note:

  • Ocarina of Time 3D: The graphics for the timed segments are clearer, and the touch-screen menu makes swapping items significantly faster. This reduces the "menu fatigue" during the Eyeball Frog and Eye Drops runs.
  • N64 / Virtual Console: The timer continues to run even while the text boxes are appearing if you aren't careful. Ensure you mash through the dialogue of the Scientist and Biggoron to save precious seconds.
  • Nintendo Switch Online: The input lag can occasionally make the mountain climb slightly more difficult when dodging falling rocks. Precision movement is key.

Common Troubleshooting and FAQ

Q: Why can't I give the Odd Mushroom to the Hag? A: You must ensure you enter the shop from the back entrance via the steps in Kakariko, not the front door. Also, check that your timer hasn't run out. If it has, the mushroom becomes a "Spilled Mushroom," and you must return to Grog.

Q: Can I use the Bolero of Fire to warp to Death Mountain? A: No. In most versions of the game, using a warp song during a timed delivery quest will cause the timer to automatically fail or the item to spoil. The quest is designed to test your knowledge of Hyrule’s geography and your riding skills with Epona.

Q: Does the Biggoron's Sword break Ganon's cape? A: In the final fight, the Biggoron's Sword is excellent for hitting Ganon's tail. However, the game scripts the very final blow to require the Master Sword. Even if you have the Biggoron’s Sword, you will need to switch to the Master Sword once Zelda holds Ganon down.

Final Verdict: Is it Worth the Effort?

The Biggoron’s Sword quest is widely considered one of the most rewarding challenges in the Zelda franchise. It encourages exploration and mastery of the game's traversal mechanics. Beyond the satisfaction of completion, the sheer power of the blade transforms the difficulty of the late-game dungeons. Whether you are a speedrunner looking to optimize boss fights or a casual player wanting an easier time in the Shadow Temple, the Biggoron’s Sword is an indispensable asset in Link’s arsenal.
