Rocktail soup

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.

A dilapidated workshop must be upgraded to the refitted version (500 slate and 2000 Bamboo), unlocking a cooking station and a bank in the workshop.

Trivia

 * Before the update on 20 August 2013, the Grand Exchange buy limit of Rocktail soup was 10 every 4 hours.
 * After the update on 16 March 2015, the soup heals a maximum of 2500 instead of 2400 life points.
 * Rocktail soup is the first food to heal more despite falling short of its Constitution requirement than the lower-tier food.
