Location and Uses
The Royal Rapier is a special Weapon that can only be wielded by Zelda after she completes the King of Hyrule's trial within Hyrule Castle. It is locked inside a blue Treasure Chest located at the end of the vault after Link and Zelda maneuver past the fireballs from Green Gargoyle and Purple Gargoyle and either cross the gap with the Hookshot or Longshot, or use the Magic Boomerang to break open the Treasure Chest and retrieve the Rapier.
- "Royal Rapier
Legendary weapon. Deals 3 damage (2 if adjacent to an enemy) and lunges you forward 1, knocking back foes at the cost of stamina." — Inventory (Cadence of Hyrule)
- "My daughter... Zelda... What has happened while I slept? ... ... I see... For generations, our family has passed down a special weapon... If you can complete the trial in the vault, take it, and put a stop to Octavo!" — King of Hyrule (Cadence of Hyrule)
