- "You obtained the Stone of Agony! If you equip a Rumble Pak, it will react to nearby...secrets."
- — In-game description
The Stone of Agony is an item from The Legend of Zelda: Ocarina of Time. It can be obtained if Link gathers 20 or more Gold Skulltula Tokens. When Link has accomplished this, he will receive the Stone of Agony as a reward for breaking the curse on one of the members of the Fabulously Rich Family living in the House of Skulltula in Kakariko Village.
When the player has a Rumble Pak (to which the Stone of Agony bears a physical resemblance) equipped in the Nintendo 64 version or a Rumble Feature in other versions, the Stone of Agony causes the controller to vibrate in response to Hidden Holes and similar secrets. Without a Rumble Pak or Rumble Feature, the Stone of Agony will be useless to the player. The Stone of Agony is included in the Virtual Console version of Ocarina of Time, but it does not support the Rumble Feature due to the design of the Classic Controller.
In The Legend of Zelda: Majora's Mask, the rumble feature is present when Link is near certain hidden things, though the Stone of Agony itself is never mentioned in the game. As a result the Rumble Feature acts more of a game mechanic in Majora's Mask.
Regardless as a result of the Stone of Agony not physically appearing or being obtainable in Majora's Mask, the Shard of Agony from Ocarina of Time 3D does not appear in Majora's Mask 3D.
Ocarina of Time 3D
In the 3DS remake, the Stone of Agony is replaced by the new Shard of Agony, which has the same function, but instead of rumbling, produces a sound and on-screen icon, this being due to the Nintendo 3DS's lack of a rumble feature.
