Gold Potion

A newly discovered potion has been found deep within the archives of Japan-Nintendo only releases within Japan. This potion has been found in the Japan-only release of:

The Legend of Zelda - A Link to the Past: Ancient Stone Tablets

You most likely have never heard of this game so i'll give you the jist of it:

ALttP: Ancient Stone Tablets is a Japan-only release of an expansion edition of ALttP which included 8 new dungeons, a new story line, and takes place 6 years after the events of ALttP. This version, although Japan-only, includes English text (for some unknown reason). Each week there would be a broadcast signal by BS-X which would allow the player to download Ancient Stone Tablets with the SNES expansion and each week would have a certain time to beat 1/4 of the game. Each week the next part would be playable and you could play it then, eventually leading up to Week 4 where the final chapter of the game was playable.

The game also introduced a new potion called a "Gold Potion". This cures all health, restores all magic, and boosts your sword charge for 10 minutes real-time. This Gold potion is only made once per day real-time and costs 50 rupees (surprisingly a fair price considering the price of red, green, and "blue potions"). This Gold Potion is considered the best potion in Ancient Stone Tablets because of it's cost and effectiveness to get the job done.

As a side note, Ancient Stone Tablets is a rather easy game compared to the original A Link to the Past.
