Making this potion grants 158 Herblore experience and requires a Clean shengo and an Aquatic vine. The potion grants the ability to catch Baron sharks, currently the second highest healing one-bite food in the game. This ability only works while fishing for regular sharks. Perfect juju fishing potions, which increase the chance of catching fish by 5% for a period of 1 hour per dose, can also be made by the addition of 10 harmony dust to 3-dose vials of juju fishing potions.
