Rocktail soup is made from one cooked rocktail and one Spice. It heals a maximum of 2,500 (with a Constitution level of at least 96) and can boost a player's life points by an extra 15%.
It can only be made after obtaining the full Rocktail Soup Recipe Scroll from Player-owned ports. It requires a Cooking level of 93 to make. Players must have the necessary level - boosts do not work. This soup cannot be burnt when being made. When made, it gives 500 base cooking experience, and the workshop boost of at least 5% also applies. Experience boosts from a clan avatar buff or from an outfit work, but cooking urns do not.
