Prerequisites

Before you can access the Greatsword, you must first unlock the following abilities:

• Hookshot

Step 1: Travel to the Stranded Sailor

Head to the Stranded Sailor, the third major area in the game and the hub for reaching Betty, one of the key bosses.

Once there:

1. Cross the docks.
2. Look in the upper-right section to spot the Greatsword behind a locked gate.
3. Read the nearby plaque—it hints that four hidden switches must be activated to unlock the gate.

Step 2: Locate and Activate the Four Hidden Switches

Each switch is tucked behind a destructible wall. You’ll need to solve environmental clues and use your Bomb ability to uncover them.

Switch 1 – Under the Stairs

• Backtrack across the docks and go underneath the stairs.
• Use the Bomb to destroy the cracked wall.
• Activate the switch inside and read the next clue.

Switch 2 – Between Twin Columns

• Go up the stairs and take the left path.
• Find two large stone columns.
• Bomb the nearby wall to reveal the passage.
• Flip the switch and examine the new clue.

Switch 3 – Behind the Giant Face

• Climb higher and locate a large carved stone face.
• Drop down, cross the bridge, and ascend again.
• Bomb the wall near the stone face to access the third switch.

Switch 4 – Beneath the Gargoyle

• Head to the top-right corner of the Stranded Sailor.
• Rotate the camera to reveal a hidden gargoyle statue above a destructible wall.
• Blow up the wall to reach the final switch.

Step 3: Unlock the Greatsword

Once all four switches are activated:

1. Return to the Greatsword gate near the docks.
2. Pull the nearby lever.
3. Step inside and claim your reward!

Bonus Tip: Magic Shrine Nearby

• Drop down the ledge.
• Follow the hidden path underground.
• You’ll find a Magic Shrine, which increases your maximum magic capacity.

Is the Greatsword Worth Using?

The Reaper’s Greatsword offers:

• +25% damage multiplier
• Extended reach

However, it comes with trade-offs:

• Only two-swing combos
• Slower attack speed compared to the standard sword

It’s great for high-damage bursts, but if you prefer speed and fluidity, the Reaper’s Sword may remain your best choice.
